Introduction

This procedure outlines how to install a UMC-400 machine.

Tools required:

  • Precision Machinist Level, 0.0005" Division
  • T-2192 SERVICE TOOL, LEVELING ADAPTER 
  • MRZP Calibration Sphere
  • Precision Granite Square 12"

Leveling Screws Hardware

Note: The washers [1] and nuts [2] are installed during shipping and should be saved for installation and not be discarded.

Note: The washer orientation [3] is important.  The conical part of the washer should be against the casting,  see illustration.

Remove Rust Inhibitor

For ease of removal, first use a plastic scraper to remove most of the rust inhibitor and then use either a heavy duty citrus cleaner or Simple Green to spray all the way covers and other non-painted surfaces that have been coated with rust inhibitor. Let it soak for a few minutes before removing it using a shop towel. It is recommended to apply mineral spirit or WD-40 to all exposed metal surfaces for rust proofing.

 Important: Do not use scotch-brite or metal scrapers, these will scratch the way covers. Furthermore, to avoid any contamination of the way cover seals with the sticky residue. Do not move any of the axes until all the rust inhibitor has been removed.

Note: The product is not hazardous and can typically be disposed of similarly to used oil.

Connect the air supply at the lube panel.

 Note: For air requirements refer to the decal that is located on the lube cabinet door.

Follow the Air Gun and Hose Installation procedure to install or replace the Air Gun.

 Note: Some installation kits will come with a spare air gun assembly.

Electrical Installation

Danger: WORKING WITH ELECTRICAL SERVICES REQUIRED FOR A CNC ARE EXTREMELY HAZARDOUS. ALL POWER TO CNC MUST BE TURNED OFF LOCKOUT-TAGOUT AT THE SOURCE PRIOR TO CONNECTING THE LINE WIRES TO CNC. HOWEVER, IF THIS NOT THE CASE OR ARE NOT SURE HOW TO DO THIS, CHECK WITH APPROPIATE PERSONNEL OR OBTAIN THE NECESSARY HELP BEFORE CONTINUING. ALWAYS CHECK THE INCOMING LINES WITH AN AC VOLTAGE DETECTOR TO MAKE SURE POWER HAS BEEN DISCONNECTED.

1

Initial Control Inspection

Danger: At this point, there should be no electrical connection to the machine. Electrical panel must be closed and secured. When main switch is on, there is HIGH VOLTAGE throughout the electrical panel (including the circuit boards and logic circuits) and some components operate at high temperatures. Therefore, exercise extreme caution when working in the panel.

  • Set the main breaker switch at the upper right of the electrical panel on the back of the machine to OFF.
  • Using a screwdriver, unlock the two latches on the panel door, unlock the cabinet with the key and open the door.
  • Take sufficient time to check all the components and connectors associated with the circuit boards. Look for any cables that have become disconnected, look for any signs damage and loose parts in the bottom of the panel box. If there are any signs that the machine was mishandled, call the factory before proceeding.

2

1-Phase Machines: Insert each power lead into the wire cover.  Connect the two power leads to L1 and L3 terminals on top of the main circuit breaker.

3-Phase Machines: Insert each power lead into the wire cover.  Connect the three power leads to L1, L2 and L3 terminals on top of the main circuit breaker.

Connect the separate ground line to the ground bus to the left of the terminals.

Refer to Haas Main Circuit Breaker - Torque Specifications for what value to torque the circuit breaker power leads.

 Note: Make sure that the leads actually go into the terminal-block clamps . (A poor connection will cause the machine to run intermittently or have other problems, such as servo overloads.) To check, simply pull on the wires after the screws are tightened.

3

After the line voltage is connected to the machine, make sure that main circuit breaker (at top-right of rear cabinet) is OFF . Remove the Lockout / Tagout and Turn ON the power at the source. Using a digital voltmeter and appropriate safety procedures: 

1-Phase Machines: Measure the AC voltage across L1 & L3 at the main circuit breaker.  The AC voltage must be between 220 - 250 volts .
Note: Lower or higher than this voltage can generate low/high voltage alarms.

3-Phase Machines : Measure the AC voltage between all three pair phases at the main circuit breaker. 

The AC voltage must be between 195 and 260 volts (360 and 480 volts for high voltage option).

SMinimill - Reboot: The AC voltage must be between 198 and 242 volts for machines without a high voltage transformer.  Refer to the Minimill/SMinimill - Identification document.

 Note: Wide voltage fluctuations are common in many industrial areas; minimum and maximum voltage supplied to a machine while it is in operation must be known. U.S. National Electrical Code specifies that machines should operate with a variation of +5% to -5% around an average supply voltage. If problems with line voltage occur, or low line voltage is suspected, an external transformer may be used. If you suspect voltage problems, voltage should be checked every hour or two during a typical day to be sure it does not fluctuate more than +5% or -5% from an average.

4

Important: With the main circuit breaker turned OFF.

Check the transformer taps at the bottom-right corner of the rear cabinet.

1-Phase Machines: The input voltage cable must be moved to the connector which corresponds to the average voltage measured in the above step.

3-Phase Machines:  The input voltage cables labeled 74, 75, and 76 must be moved to the terminal block triple which corresponds to the average voltage measured in the above step.

5

Transformer T5 supplies 24VAC used to power the main contactor. There are two versions of this transformer for use on a 240 and 400V machines. The 240V transformer has two input connectors located about two inches from the transformer, which allow it to be connected to either 180-220V or 221-240V.

Users that have 220V-240V RMS input power should use the connector labeled 221-240V, while users with 190-220V input power should use the connector labeled 180-220V. Failure to use the correct input connector will result in either overheating of the main contactor or failure to reliably engage the main contactor.

The 480V (option) T5 transformer has three input connectors, labeled 340-380V, 381-440V and 441-480V.

Users with 340-380V 50/60Hz power should use the 340-380V connector while users with 380V-440V 50/60Hz power should use the 381-440V connector.

Important: Set the main circuit breaker to ON. Check for evidence of problems, such as the smell of overheating components or smoke. If such problems are indicated, immediately set the main circuit breaker to OFF and call the factory before proceeding.

After the power is on, measure the voltage across the bottom terminals on the main circuit breaker. It should be the same as the measurements where the input power connects to the main breaker. If there are any problems, check the wiring.

6

Apply power to the control by pressing the Power-On switch on the front panel.

Check the DC Voltage and AC Line Voltage gauges in Diagnostics. The DC Voltage gauge must read between 310 - 360V. The AC Line Voltage must be between 90 and 105 percent. If the voltage is outside these limits, turn off the power and recheck steps 2 and 3. If the voltage is still outside these limits, call the factory.

7

Electrical power must be phased properly to avoid damage to your equipment. The Power Supply Assembly PC board incorporates a "Phase Detect" circuit with neon indicators. When the orange neon is lit (NE5), the phasing is incorrect. If the green neon is lit (NE6), the phasing is correct. If both neon indicators are lit, you have a loose wire; check the connections. Adjust phasing by setting the source power to off and then swapping L1 and L2 of the incoming power lines at the main circuit breaker.

Danger: ALL POWER TO CNC MUST BE TURNED OFF LOCKOUT-TAGOUT AT THE SOURCE PRIOR TO ADJUSTING PHASING. ALWAYS DOUBLE CHECK THE INCOMING LINES WITH AN AC VOLTAGE DETECTOR.

Turn off the power and set the main circuit breaker to OFF. Close the door, lock the latches, and turn the power back on.

Remove the key from the control cabinet and give it to the shop manager.

8

Activation

When the machine is properly placed and connected to both air and electrical power, it is ready for final installation (removing shipping blocks, leveling, spindle sweep, etc.) and software activation. The HFO service technician does this. Contact the local HFO to schedule the work.

Shipping Brackets Removal

1

Remove the door shipping bracket [1] from the door.

2

Remove the rear panels and remove the four shoulder bolts [1] for the X and Y axes at the back of the bridge.

 

3

Raise the Z-axis [1] and remove the shipping bracket [2].  The Z axis is not bolted to the bracket, it only sits on top of the bracket.

4

Remove the shipping bracket [1] from the WIPS stand [2] and install the stand into the WIPS mount position on the base.

Machine Rough Leveling

This section tells you how to correctly level and check geometric alignment on a UMC. The machine must be leveled and checked for proper geometric alignment before it will provide optimal performance and accuracy.

Important: Before attempting this procedure the machine must have air and power connected and be operational.

 Note: It is recommended for machines with CDF conveyors to do a fitment check for the coolant tank and the CDF conveyor before leveling.

1

Zero return each axis one at a time or press [POWER UP]. Go through the leveling process.

Repeat these steps to achieve correct machine level.

2

Adjust the (4) corner leveling screws to lift the casting off of the ground.

Set [H] to 4".

 

3

Place the precision level [1] on one of the X-Axis linear guide. 

First level the machine side to side. Lift or lower one side with even adjustments of the two screws [2] to center the bubble in the tool.

4

Place the precision level parallel to the Y-Axis on the linear guide.

 Note:  You can also place a granite block across the X-axis linear guides, and put the precision level on top. 

Adjust either the front or back screws evenly to level the machine front to back and center the bubble in the level tool.

X-Axis Roll Adjustment

With the Y-Axis and Z-Axis at mid-travel, set the leveling tool (T-2181A / T-2192) parallel to the Y-Axis.

 Note:  Leveling tool (T-2182/T-2192) needs to be manually adjusted after mounted to the spindle.  Snug the mag base mounting bolt and bump the level by hand until the bubble level is in the middle of the travel.

 Note: For better results position the Z-axis closest to the work envelope as possible.

Handle jog X-axis. Take readings at the Home, the middle, and at the end of X-Axis travel. At the end of X-Axis travel, note whether the front or back side of the machine is lower.

Raise or lower side, [1] or [2], until the bubble in the tool reads zero. Repeat this step at each end of travel until the tool reads zero at both ends.

B-Axis to Y-Axis Parallelism Setup

1

[ZERO RETURN] [B] [C] Axis. Indicate the table face along the X-Axis over a distance of 15" (381mm).

If the reading is not zero, jog the B-axis (in 0.0001" increments) until the indicator reads zero over 15". Note the B-axis position for later.

2

Handle Jog C Axis to C90. Check the parallelism of the table surface to the Y-Axis in the up and down direction.

Zero your indicator at the back, on the table face. Sweep forward with the Y-Axis over 15" (381 mm). Record the indicator reading, noting both the magnitude and the direction.

 

3

Add 90 degrees to the value you adjusted B-Axis to earlier. Command the B-Axis to this position (for example B90.003 degrees).

Zero the indicator on the rear table face and jog the Y Axis from back to front over 15" (381 mm). Record the indicator reading, noting both the magnitude and the direction. This measurement shows the position of the table relative to the Y-Axis in the side to side direction.

If the trunnion leans to the right, lift with the right front leveling screw and lower with the left front leveling screw in small, equal, increments.

If the trunnion leans to the left, lift with the left front leveling screw, lower with the right front.

Sweep the table again to make sure that it is aligned to read zero over the 15" (381mm) sweep.

B-Axis and C-Axis Home Position Check

[ZERO RETURN] [B] and indicate the table surface [1]. Sweep the table over 20 inches (500 mm), with the value NTE 0.001"/15" (0.025 mm/381 mm).

[ZERO RETURN] [C] and indicate one of the t-slot walls [2] over 15" (381 mm), with the error value not to exceed (NTE) 0.001"/15" (0.025 mm/ 381 mm).

Note: If either reading is higher than one thousandth (0.001", 0.025mm), repeat the machine leveling process. Small errors in the leveling sequence can negatively influence the B and C home positions.

If you verify the level is correct but the B or C home positions are still not within specification, you can slightly adjust the left or right front screw to change the B and C home positions a small amount. Check both home positions after you make any adjustments.

Spindle Sweep Check

Move the spindle head to the middle of the Z-Axis travel. Position the test indicator on the spindle to measure a 10" (250mm) diameter circle at the center of the table. Zero the test indicator at the operator side of the table [1].

Take a measurement every 90 degrees of rotation, [2], [3], [4]. Total indicated runout (TIR) for all four positions is not to exceed (NTE) 0.0005" (0.012 mm).

Note: The spindle sweep values are also affected by the precision of the leveling sequence; if the values exceed specification, check the machine level again.

Note: If equipped with the 50 pocket tool changer check the alignment to the spindle.

Install and Calibrate WIPS

1

Install and calibrate the Wireless Intuitive Probe System (WIPS) (if equipped).

For an in depth guide on WIPS installation and calibration, please see:

WIPS Installation

Note: Have the the probe on the OTS facing towards the front of the machine.

MRZP Offsets Settings

1

This tells you how to set Machine Rotary Zero Point (MRZP) Offsets. The MRZP Offsets are settings in the Haas CNC control that tell the control these distances:

  1. the distance of the tilt axis (B axis) centerline from the X-Axis home position
  2. the distance of the tilt axis (B axis) centerline from the Z-Axis home position
  3. the distance of the table rotary axis (C axis) centerline from the Y-Axis home position

This procedure shows images that use both calibration assemblies.

 Important: The spindle probe must be calibrated before doing this procedure. This makes sure the accuracy of the probe to the machine position is correct. Refer to the Next Generation Control - Probe Calibration (VPS) procedure, in the diy.haascnc.com

2

Press [Setting] and navigate to Machine Setup. Check settings 255, 256, and 257. The values should not be zero. If they are perform the following procedure.

MRZP A-C or B-C Axis Rough Set

Note: A-C Or B-C MRZP ROUGH SET is used only when there are no MZRP offset settings (255, 256, 257) set.

5

Enter the diameter of the tooling ball [2].

Important: Always measure the tooling ball with a calibrated micrometer to ensure the correct ball diameter.

 Note: If you are in metric mode make sure you enter the ball size in millimeters. If you are in inch mode enter the ball size in inches

Push [ENTER] .

Push [F4] .

Select Output MDI .

  

6

Install the calibration sphere assembly [1] near the center of the platter.

Note:  On a UMC-1000 if the calibration sphere is too far out from the center, an overtravel alarm will be generated during the MRZP calibration cycle.

Make sure that the tooling ball [2] is tightly attached to the calibration assembly.

Note:  On UMC machines that are equipped with the Pallet Pool the calibration sphere will need to be secured to the pallet using toe clamps.

Note: Do not over-tighten the tooling ball.

Jog the Z Axis until the probe tip [2] is 0.1" (2.54 mm) above and centered over the tooling ball [1].

Start the program in MDI. This program is O099994 B AXIS TILT AND C AXIS ROT AXIS .

7

The probe measures many positions on the B and C axes at different degrees.

The program puts values in macro variables 10121, 10122, and 10123. Record those values.

8

Put the recorded values in these settings:

  • Enter the value for macro variable 10121 in setting 255; MRZP X Offset.
  • Enter the value for macro variable 10122 in setting 256; MRZP Y Offset.
  • Enter the value for macro variable 10123 in setting 257; MRZP Z Offset.

If you think that you possibly entered incorrect numbers, start the MRZP FINISH SET program again. The values that the program puts into the variables must be within five counts or less of the setting numbers.

 Note: Setting 9 determines if the values are shown in inches or millimeters.

Rear Panel - Installation

Install the rear panels. Refer to the decal that is located behind the machine.

Users that have 220V-240V RMS input power should use the connector labeled 221-240V, while users with 190-220V input power should use the connector labeled 180-220V. Failure to use the correct input connector will result in either overheating of the main contactor or failure to reliably engage the main contactor.

The 480V (option) T5 transformer has three input connectors, labeled 340-380V, 381-440V and 441-480V.

Users with 340-380V 50/60Hz power should use the 340-380V connector while users with 380V-440V 50/60Hz power should use the 381-440V connector.

Important: Set the main circuit breaker to ON. Check for evidence of problems, such as the smell of overheating components or smoke. If such problems are indicated, immediately set the main circuit breaker to OFF and call the factory before proceeding.

After the power is on, measure the voltage across the bottom terminals on the main circuit breaker. It should be the same as the measurements where the input power connects to the main breaker. If there are any problems, check the wiring.

6

Apply power to the control by pressing the Power-On switch on the front panel.

Check the DC Voltage and AC Line Voltage gauges in Diagnostics. The DC Voltage gauge must read between 310 - 360V. The AC Line Voltage must be between 90 and 105 percent. If the voltage is outside these limits, turn off the power and recheck steps 2 and 3. If the voltage is still outside these limits, call the factory.

7

Electrical power must be phased properly to avoid damage to your equipment. The Power Supply Assembly PC board incorporates a "Phase Detect" circuit with neon indicators. When the orange neon is lit (NE5), the phasing is incorrect. If the green neon is lit (NE6), the phasing is correct. If both neon indicators are lit, you have a loose wire; check the connections. Adjust phasing by setting the source power to off and then swapping L1 and L2 of the incoming power lines at the main circuit breaker.

Danger: ALL POWER TO CNC MUST BE TURNED OFF LOCKOUT-TAGOUT AT THE SOURCE PRIOR TO ADJUSTING PHASING. ALWAYS DOUBLE CHECK THE INCOMING LINES WITH AN AC VOLTAGE DETECTOR.

Turn off the power and set the main circuit breaker to OFF. Close the door, lock the latches, and turn the power back on.

Remove the key from the control cabinet and give it to the shop manager.

8

Take the cable and hose out of the hole in the sheet metal panel where the motor assembly is mounted and install the motor cable [1] to the motor  and the motor engagement hose [2] to the air cylinder. 

A wiring diagram is added below for reference. 

 

Machine Rough Leveling

This section tells you how to correctly level and check geometric alignment on a UMC. The machine must be leveled and checked for proper geometric alignment before it will provide optimal performance and accuracy.

Important: Before attempting this procedure the machine must have air and power connected and be operational.

 Note: It is recommended for machines with CDF conveyors to do a fitment check for the coolant tank and the CDF conveyor before leveling.

1

Zero return each axis one at a time or press [POWER UP]. Go through the leveling process.
Repeat these steps to achieve correct machine level.

2

Adjust the (4) corner leveling screws to lift the casting off of the ground.

Set [H] to 4".

Turn both middle leveling screws [1] up off the middle pads.

 

3

Place the precision level [1] on one of the X-Axis linear guide. 

First level the machine side to side. Lift or lower one side with even adjustments of the two screws [2] to center the bubble in the tool.

4

Place the precision level parallel to the Y-Axis on the linear guide.

Note:  You can also place a granite block across the X-axis linear guides, and put the precision level on top. 

Adjust either the front or back screws evenly to level the machine front to back and center the bubble in the level tool.

X-Axis Roll Adjustment

With the Y-Axis at mid-travel, set the leveling tool (T-2182 / T-2192) parallel to the Y-Axis.

 Note:  Leveling tool (T-2182/T-2192) needs to be manually adjusted after mounted to the spindle.  Snug the mag base mounting bolt and bump the level by hand until the bubble level is in the middle of the travel.

 Note: For better results position the Z-axis closest to the work envelope as possible.

Handle jog X-axis. Take readings at the Home, the middle, and at the end of X-Axis travel. At the end of X-Axis travel, note whether the front or back side of the machine is lower.

Raise or lower side, [1] or [2], until the bubble in the tool reads zero. Repeat this step at each end of travel until the tool reads zero at both ends.

B-Axis to Y-Axis Parallelism Setup

1

[ZERO RETURN] [B] [C] Axis. Indicate the table face along the X-Axis over a distance of 15" (381mm).

If the reading is not zero, jog the B-axis (in 0.0001" increments) until the indicator reads zero over 15". Note the B-axis position for later.

2

Handle Jog C Axis to C90. Check the parallelism of the table surface to the Y-Axis in the up and down direction.

Zero your indicator at the back, on the table face. Sweep forward with the Y-Axis over 15" (381 mm). Record the indicator reading, noting both the magnitude and the direction.

Use the middle leveling screws to raise the middle of the machine and adjust the B-Axis. Turn the middle leveling screws down until they just contact the leveling pads and then turn them down an additional 10 degrees.

The middle of the machine will always need to be raised initially. Adjust the middle screws evenly on each side. Always make adjustments in small increments and set both middle screws evenly on either side with each adjustment.

Continue to adjust the middle screws up or down until the indicator reads zero over the 15" (381 mm) sweep.

3

Add 90 degrees to the value you adjusted B-Axis to earlier. Command the B-Axis to this position (for example B90.003 degrees).

Zero the indicator on the rear table face and jog the Y Axis from back to front over 15" (381 mm). Record the indicator reading, noting both the magnitude and the direction. This measurement shows the position of the table relative to the Y-Axis in the side to side direction.

If the trunnion leans to the right, lift with the right front leveling screw and lower with the left front leveling screw in small, equal, increments.

If the trunnion leans to the left, lift with the left front leveling screw, lower with the right front.

Sweep the table again to make sure that it is aligned to read zero over the 15" (381mm) sweep.

B-Axis and C-Axis Home Position Check

[ZERO RETURN] [C] and indicate one of the t-slot walls [1] over 15" (381 mm), with the error value not to exceed (NTE) 0.001"/15" (0.025 mm/ 381 mm).

[ZERO RETURN] [B] and indicate the table surface [2]. Sweep the table over 15 inches (381 mm), with the value NTE 0.001"/15" (0.025 mm/381 mm).

Note: If either reading is higher than one thousandth (0.001", 0.025mm), repeat the machine leveling process. Small errors in the leveling sequence can negatively influence the B and C home positions.

If you verify the level is correct but the B or C home positions are still not within specification, you can slightly adjust the left or right front screw to change the B and C home positions a small amount. Check both home positions after you make any adjustments.

Spindle Sweep Check

Move the spindle head to the middle of the Z-Axis travel. Position the test indicator on the spindle to measure a 10" (250mm) diameter circle at the center of the table. Zero the test indicator at the operator side of the table [1].

Take a measurement every 90 degrees of rotation, [2], [3], [4]. Total indicated runout (TIR) for all four positions is not to exceed (NTE) 0.0005" (0.012 mm).

Note: The spindle sweep values are also affected by the precision of the leveling sequence; if the values exceed specification, check the machine level again.

Note: If equipped with the 50 pocket tool changer check the alignment to the spindle.

MRZP Offsets Settings

1

This tells you how to set Machine Rotary Zero Point (MRZP) Offsets. The MRZP Offsets are settings in the Haas CNC control that tell the control these distances:

  1. the distance of the tilt axis (B axis) centerline from the X-Axis home position
  2. the distance of the tilt axis (B axis) centerline from the Z-Axis home position
  3. the distance of the table rotary axis (C axis) centerline from the Y-Axis home position

This procedure shows images that use both calibration assemblies.

 Important: The spindle probe must be calibrated before doing this procedure. This makes sure the accuracy of the probe to the machine position is correct. Refer to the Next Generation Control - Probe Calibration (VPS) procedure, in the diy.haascnc.com

Install the calibration sphere assembly [1] near the center of the platter.

Note:  On a UMC-1000 if the calibration sphere is too far out from the center, an overtravel alarm will be generated during the MRZP calibration cycle.

Make sure that the tooling ball [2] is tightly attached to the calibration assembly.

Note:  On UMC machines that are equipped with the Pallet Pool the calibration sphere will need to be secured to the pallet using toe clamps.

Note: Do not over-tighten the tooling ball.

Jog the Z Axis until the probe tip [2] is 0.1" (2.54 mm) above and centered over the tooling ball [1].

Start the program in MDI. This program is O099994 B AXIS TILT AND C AXIS ROT AXIS .

7

The probe measures many positions on the B and C axes at different degrees.

The program puts values in macro variables 10121, 10122, and 10123. Record those values.

8

Put the recorded values in these settings:

  • Enter the value for macro variable 10121 in setting 255; MRZP X Offset.
  • Enter the value for macro variable 10122 in setting 256; MRZP Y Offset.
  • Enter the value for macro variable 10123 in setting 257; MRZP Z Offset.

If you think that you possibly entered incorrect numbers, start the MRZP FINISH SET program again. The values that the program puts into the variables must be within five counts or less of the setting numbers.

 Note: Setting 9 determines if the values are shown in inches or millimeters.

3.3 UMC-750

UMC-750 Installation - NGC

Introduction

This procedure will show you how to install a UMC-750\SS machine. 

Click on the link to see the  UMC-750 Leveling and Alignment video. 

Tools required:

  • Precision Machinist Level, 0.0005" Division
  • T-2192 SERVICE TOOL, LEVELING ADAPTER 
  • MRZP Calibration Sphere
  • Precision Granite Block 20" (optional)

Leveling Screws Hardware

Note: The washers [1] and nuts [2] are installed during shipping and should be saved for installation and not be discarded.

Note: The washer orientation [3] is important.  The conical part of the washer should be against the casting,  see illustration.

Remove Rust Inhibitor

For ease of removal, first use a plastic scraper to remove most of the rust inhibitor and then use either a heavy duty citrus cleaner or Simple Green to spray all the way covers and other non-painted surfaces that have been coated with rust inhibitor. Let it soak for a few minutes before removing it using a shop towel. It is recommended to apply mineral spirit or WD-40 to all exposed metal surfaces for rust proofing.

 Important: Do not use scotch-brite or metal scrapers, these will scratch the way covers. Furthermore, to avoid any contamination of the way cover seals with the sticky residue. Do not move any of the axes until all the rust inhibitor has been removed.

Note: The product is not hazardous and can typically be disposed of similarly to used oil.

Follow the Air Gun and Hose Installation procedure to install or replace the Air Gun.

 Note: Some installation kits will come with a spare air gun assembly.

Electrical Installation

Danger: WORKING WITH ELECTRICAL SERVICES REQUIRED FOR A CNC ARE EXTREMELY HAZARDOUS. ALL POWER TO CNC MUST BE TURNED OFF LOCKOUT-TAGOUT AT THE SOURCE PRIOR TO CONNECTING THE LINE WIRES TO CNC. HOWEVER, IF THIS NOT THE CASE OR ARE NOT SURE HOW TO DO THIS, CHECK WITH APPROPIATE PERSONNEL OR OBTAIN THE NECESSARY HELP BEFORE CONTINUING. ALWAYS CHECK THE INCOMING LINES WITH AN AC VOLTAGE DETECTOR TO MAKE SURE POWER HAS BEEN DISCONNECTED.

1

Initial Control Inspection

Danger: At this point, there should be no electrical connection to the machine. Electrical panel must be closed and secured. When main switch is on, there is HIGH VOLTAGE throughout the electrical panel (including the circuit boards and logic circuits) and some components operate at high temperatures. Therefore, exercise extreme caution when working in the panel.

  • Set the main breaker switch at the upper right of the electrical panel on the back of the machine to OFF.
  • Using a screwdriver, unlock the two latches on the panel door, unlock the cabinet with the key and open the door.
  • Take sufficient time to check all the components and connectors associated with the circuit boards. Look for any cables that have become disconnected, look for any signs damage and loose parts in the bottom of the panel box. If there are any signs that the machine was mishandled, call the factory before proceeding.

2

1-Phase Machines: Insert each power lead into the wire cover.  Connect the two power leads to L1 and L3 terminals on top of the main circuit breaker.

3-Phase Machines: Insert each power lead into the wire cover.  Connect the three power leads to L1, L2 and L3 terminals on top of the main circuit breaker.

Connect the separate ground line to the ground bus to the left of the terminals.

Refer to Haas Main Circuit Breaker - Torque Specifications for what value to torque the circuit breaker power leads.

 Note: Make sure that the leads actually go into the terminal-block clamps . (A poor connection will cause the machine to run intermittently or have other problems, such as servo overloads.) To check, simply pull on the wires after the screws are tightened.

3

After the line voltage is connected to the machine, make sure that main circuit breaker (at top-right of rear cabinet) is OFF . Remove the Lockout / Tagout and Turn ON the power at the source. Using a digital voltmeter and appropriate safety procedures: 

1-Phase Machines: Measure the AC voltage across L1 & L3 at the main circuit breaker.  The AC voltage must be between 220 - 250 volts .
Note: Lower or higher than this voltage can generate low/high voltage alarms.

3-Phase Machines : Measure the AC voltage between all three pair phases at the main circuit breaker. 

The AC voltage must be between 195 and 260 volts (360 and 480 volts for high voltage option).

SMinimill - Reboot: The AC voltage must be between 198 and 242 volts for machines without a high voltage transformer.  Refer to the Minimill/SMinimill - Identification document.

 Note: Wide voltage fluctuations are common in many industrial areas; minimum and maximum voltage supplied to a machine while it is in operation must be known. U.S. National Electrical Code specifies that machines should operate with a variation of +5% to -5% around an average supply voltage. If problems with line voltage occur, or low line voltage is suspected, an external transformer may be used. If you suspect voltage problems, voltage should be checked every hour or two during a typical day to be sure it does not fluctuate more than +5% or -5% from an average.

4

Important: With the main circuit breaker turned OFF.

Check the transformer taps at the bottom-right corner of the rear cabinet.

1-Phase Machines: The input voltage cable must be moved to the connector which corresponds to the average voltage measured in the above step.

3-Phase Machines:  The input voltage cables labeled 74, 75, and 76 must be moved to the terminal block triple which corresponds to the average voltage measured in the above step.

5

Transformer T5 supplies 24VAC used to power the main contactor. There are two versions of this transformer for use on a 240 and 400V machines. The 240V transformer has two input connectors located about two inches from the transformer, which allow it to be connected to either 180-220V or 221-240V.

Users that have 220V-240V RMS input power should use the connector labeled 221-240V, while users with 190-220V input power should use the connector labeled 180-220V. Failure to use the correct input connector will result in either overheating of the main contactor or failure to reliably engage the main contactor.

The 480V (option) T5 transformer has three input connectors, labeled 340-380V, 381-440V and 441-480V.

Users with 340-380V 50/60Hz power should use the 340-380V connector while users with 380V-440V 50/60Hz power should use the 381-440V connector.

Important: Set the main circuit breaker to ON. Check for evidence of problems, such as the smell of overheating components or smoke. If such problems are indicated, immediately set the main circuit breaker to OFF and call the factory before proceeding.

After the power is on, measure the voltage across the bottom terminals on the main circuit breaker. It should be the same as the measurements where the input power connects to the main breaker. If there are any problems, check the wiring.

6

Apply power to the control by pressing the Power-On switch on the front panel.

Check the DC Voltage and AC Line Voltage gauges in Diagnostics. The DC Voltage gauge must read between 310 - 360V. The AC Line Voltage must be between 90 and 105 percent. If the voltage is outside these limits, turn off the power and recheck steps 2 and 3. If the voltage is still outside these limits, call the factory.

7

Electrical power must be phased properly to avoid damage to your equipment. The Power Supply Assembly PC board incorporates a "Phase Detect" circuit with neon indicators. When the orange neon is lit (NE5), the phasing is incorrect. If the green neon is lit (NE6), the phasing is correct. If both neon indicators are lit, you have a loose wire; check the connections. Adjust phasing by setting the source power to off and then swapping L1 and L2 of the incoming power lines at the main circuit breaker.

Danger: ALL POWER TO CNC MUST BE TURNED OFF LOCKOUT-TAGOUT AT THE SOURCE PRIOR TO ADJUSTING PHASING. ALWAYS DOUBLE CHECK THE INCOMING LINES WITH AN AC VOLTAGE DETECTOR.

Turn off the power and set the main circuit breaker to OFF. Close the door, lock the latches, and turn the power back on.

Remove the key from the control cabinet and give it to the shop manager.

8

Activation

When the machine is properly placed and connected to both air and electrical power, it is ready for final installation (removing shipping blocks, leveling, spindle sweep, etc.) and software activation. The HFO service technician does this. Contact the local HFO to schedule the work.

UMC Autodoor Motor Installation

1

Install the motor assembly [1] to the sheet metal above the door using the provided hardware, (2x) 1/4-20 FBHCS [2]. 

 NOTE: Earlier revisions of the autodoor will not have the revised pemnuts on the enclosure panel, if the enclosure does not, use (2x)  1/4-20 FBHCS and (2x) flanged nut to install the motor assembly. 

2

Install the motor cover [1] over the motor assembly and use the provided self drillling/tapping screw [2] to fully install the motor cover to the assembly. 

NOTE: Make sure the screw [2] does not drill into the nitrile bumper [3]  as shown in the bottom image. 

NOTE: The motor cover has a magnet [4] that helps hold the motor into position along with the screw, be sure to position the cover correctly before drilling. 

3

Machines that receive the autodoor as an option have the cable and hose already routed.

Take the cable and hose out of the hole in the sheet metal panel where the motor assembly is mounted and install the motor cable [1] to the motor  and the motor engagement hose [2] to the air cylinder. 

A wiring diagram is added below for reference. 

Machine Rough Leveling

This section tells you how to correctly level and check geometric alignment on a UMC. The machine must be leveled and checked for proper geometric alignment before it will provide optimal performance and accuracy.

Important: Before attempting this procedure the machine must have air and power connected and be operational.

 Note: It is recommended for machines with CDF conveyors to do a fitment check for the coolant tank and the CDF conveyor before leveling.

1

Zero return each axis one at a time or press [POWER UP]. Go through the leveling process.
Repeat these steps to achieve correct machine level.

2

Adjust the (4) corner leveling screws to lift the casting off of the ground.

Set [H] to 4".

Turn both middle leveling screws [1] up off the middle pads.

 

3

Place the precision level [1] on one of the X-Axis linear guide. 

First level the machine side to side. Lift or lower one side with even adjustments of the two screws [2] to center the bubble in the tool.

4

Place the precision level parallel to the Y-Axis on the linear guide.

Note:  You can also place a granite block across the X-axis linear guides, and put the precision level on top. 

Adjust either the front or back screws evenly to level the machine front to back and center the bubble in the level tool.

X-Axis Roll Adjustment

With the Y-Axis and Z-Axis at mid-travel, set the leveling tool (T-2181A / T-2192) parallel to the Y-Axis.

 Note:  Leveling tool (T-2182/T-2192) needs to be manually adjusted after mounted to the spindle.  Snug the mag base mounting bolt and bump the level by hand until the bubble level is in the middle of the travel.

 Note: For better results position the Z-axis closest to the work envelope as possible.

Handle jog X-axis. Take readings at the Home, the middle, and at the end of X-Axis travel. At the end of X-Axis travel, note whether the front or back side of the machine is lower.

Raise or lower side, [1] or [2], until the bubble in the tool reads zero. Repeat this step at each end of travel until the tool reads zero at both ends.

B-Axis to Y-Axis Parallelism Setup

1

[ZERO RETURN] [B] [C] Axis. Indicate the table face along the X-Axis over a distance of 15" (381mm).

If the reading is not zero, jog the B-axis (in 0.0001" increments) until the indicator reads zero over 15". Note the B-axis position for later.

2

Handle Jog C Axis to C90. Check the parallelism of the table surface to the Y-Axis in the up and down direction.

Zero your indicator at the back, on the table face. Sweep forward with the Y-Axis over 15" (381 mm). Record the indicator reading, noting both the magnitude and the direction.

Use the middle leveling screws to raise the middle of the machine and adjust the B-Axis. Turn the middle leveling screws down until they just contact the leveling pads and then turn them down an additional 10 degrees.

The middle of the machine will always need to be raised initially. Adjust the middle screws evenly on each side. Always make adjustments in small increments and set both middle screws evenly on either side with each adjustment.

Continue to adjust the middle screws up or down until the indicator reads zero over the 15" (381 mm) sweep.

3

Add 90 degrees to the value you adjusted B-Axis to earlier. Command the B-Axis to this position (for example B90.003 degrees).

Zero the indicator on the rear table face and jog the Y Axis from back to front over 15" (381 mm). Record the indicator reading, noting both the magnitude and the direction. This measurement shows the position of the table relative to the Y-Axis in the side to side direction.

If the trunnion leans to the right, lift with the right front leveling screw and lower with the left front leveling screw in small, equal, increments.

If the trunnion leans to the left, lift with the left front leveling screw, lower with the right front.

Sweep the table again to make sure that it is aligned to read zero over the 15" (381mm) sweep.

B-Axis and C-Axis Home Position Check

[ZERO RETURN] [B] and indicate the table surface [1]. Sweep the table over 20 inches (500 mm), with the value NTE 0.001"/15" (0.025 mm/381 mm).

[ZERO RETURN] [C] and indicate one of the t-slot walls [2] over 15" (381 mm), with the error value not to exceed (NTE) 0.001"/15" (0.025 mm/ 381 mm).

Note: If either reading is higher than one thousandth (0.001", 0.025mm), repeat the machine leveling process. Small errors in the leveling sequence can negatively influence the B and C home positions.

If you verify the level is correct but the B or C home positions are still not within specification, you can slightly adjust the left or right front screw to change the B and C home positions a small amount. Check both home positions after you make any adjustments.

Spindle Sweep Check

Move the spindle head to the middle of the Z-Axis travel. Position the test indicator on the spindle to measure a 10" (250mm) diameter circle at the center of the table. Zero the test indicator at the operator side of the table [1].

Take a measurement every 90 degrees of rotation, [2], [3], [4]. Total indicated runout (TIR) for all four positions is not to exceed (NTE) 0.0005" (0.012 mm).

Note: The spindle sweep values are also affected by the precision of the leveling sequence; if the values exceed specification, check the machine level again.

Note: If equipped with the 50 pocket tool changer check the alignment to the spindle.

MRZP Offsets Settings

1

This tells you how to set Machine Rotary Zero Point (MRZP) Offsets. The MRZP Offsets are settings in the Haas CNC control that tell the control these distances:

  1. the distance of the tilt axis (B axis) centerline from the X-Axis home position
  2. the distance of the tilt axis (B axis) centerline from the Z-Axis home position
  3. the distance of the table rotary axis (C axis) centerline from the Y-Axis home position

This procedure shows images that use both calibration assemblies.

 Important: The spindle probe must be calibrated before doing this procedure. This makes sure the accuracy of the probe to the machine position is correct. Refer to the Next Generation Control - Probe Calibration (VPS) procedure, in the diy.haascnc.com

2

Press [Setting] and navigate to Machine Setup. Check settings 255, 256, and 257. The values should not be zero. If they are perform the following procedure.

MRZP A-C or B-C Axis Rough Set

Note: A-C Or B-C MRZP ROUGH SET is used only when there are no MZRP offset settings (255, 256, 257) set.

5

Enter the diameter of the tooling ball [2].

Important: Always measure the tooling ball with a calibrated micrometer to ensure the correct ball diameter.

 Note: If you are in metric mode make sure you enter the ball size in millimeters. If you are in inch mode enter the ball size in inches

Push [ENTER] .

Push [F4] .

Select Output MDI .

  

6

Install the calibration sphere assembly [1] near the center of the platter.

Note:  On a UMC-1000 if the calibration sphere is too far out from the center, an overtravel alarm will be generated during the MRZP calibration cycle.

Make sure that the tooling ball [2] is tightly attached to the calibration assembly.

Note:  On UMC machines that are equipped with the Pallet Pool the calibration sphere will need to be secured to the pallet using toe clamps.

Note: Do not over-tighten the tooling ball.

Jog the Z Axis until the probe tip [2] is 0.1" (2.54 mm) above and centered over the tooling ball [1].

Start the program in MDI. This program is O099994 B AXIS TILT AND C AXIS ROT AXIS .

7

The probe measures many positions on the B and C axes at different degrees.

The program puts values in macro variables 10121, 10122, and 10123. Record those values.

8

Put the recorded values in these settings:

  • Enter the value for macro variable 10121 in setting 255; MRZP X Offset.
  • Enter the value for macro variable 10122 in setting 256; MRZP Y Offset.
  • Enter the value for macro variable 10123 in setting 257; MRZP Z Offset.

If you think that you possibly entered incorrect numbers, start the MRZP FINISH SET program again. The values that the program puts into the variables must be within five counts or less of the setting numbers.

 Note: Setting 9 determines if the values are shown in inches or millimeters.

Complete & Submit Inspection Report
