Introduction

Note: The location of the oil reservoir is different on some machines.

The CALM - Haas Axis Lubrication Oil system is a restrictor oil flow system that pumps oil through flexible plastic tubing and copper tubes to the axes.

 

Identification

Use the illustration to identify the parts of the lubrication system.

Note: For recommended lubricant types, see Lubricant Table for Haas Machine Components.

  1. Oil Pressure Switch - Monitors the oil system pressure and sends a signal to the control to generate an alarm if the pressure drops below the minimum level too quickly.
  2. Oil Pressure Gauge - Shows the pressure (in psi and bar) of the oil system.
  3. Oil Filter Wrench - Removes the oil reservoir.
  4. Oil Reservoir Assembly - Stores the oil.
  5. Air-Lube Panel Decal - Shows the color-coded cables that connect each solenoid.
  6. Oil Reservoir - Stores the oil that lubricates the spindle.
  7. Air Manifold Assembly - Supplies air to the machine.
  8. Axis-Lube Air Solenoid - Pressurizes the oil reservoir.
  9. Air Pressure Gauge - Shows the pressure (in psi and bar) at which the air is supplied.
  10. Electronic Analog Air Pressure Sensor - Monitors the air system pressure and sends a signal to the control to generate an alarm if the pressure drops below the minimum level for a set period of time.

Axis Lubrication

The oil reservoir [1] lubricates the axes at a rate of (1) oil cycle for every 3 hours of axis travel.

Oil moves from the oil reservoir [1] through flexible plastic tubing [2] to the axis manifolds [3].

Note: The number of axis manifolds may be different on some machines.

Note: Each axis has (1) ballnut [4] and (4-6 ) linear guide trucks [5].

 

Oil moves from the axis manifolds [3] through copper tubes. The copper tubes lubricate the ballnuts [4] and the linear guide trucks [5].

Note: There is (1) copper tube that goes to the ballnut and (1) copper tube that goes to each linear guide truck.

 

Note: The Haas Axis Lubrication Oil canister lasts approximately 10 months to a year under normal machine operation, 8 hours a day and 5 days per week.

 

Axis Manifold Fitting Information

The Haas Axis Lubrication Oil system uses adapter fittings [1] in the axis manifolds. The linear guide trucks and ballnuts use restrictor fittings [2]. The restrictor fitting has a gap [4] between the threads and the set screw [3]. This forces the manifold-fed oil to pass through the gap [4] to lubricate the axes.

Note: The copper tubes on this system may or may not be equal length.

Caution: Do not change the length of the copper tubes or flexible plastic tubing. This changes the flow of oil.

 

Haas Axis Lubrication Oil - Reservoir Refill

AD0630

Introduction

This procedure outlines how to refill the Haas Axis Lubrication Oil reservoir.

Axis Lubrication Has Changed From Grease to Oil - Service Update

This procedure applies to the following service kits:

  • 93-3584: AXIS LUBE OIL REFILL 1 GALLON

Haas Axis Lubrication Oil - Refill

1

Power off the machine. Close the primary air valve. This stops the air supply to the machine.

Pull the ring on the pressure relief valve on the air and lubrication manifold. This releases the air pressure from the system.

Place shop towels under the reservoir to catch any grease that may fall.

Remove the empty reservoir. Use an automotive oil filter wrench to loosen it if the reservoir is too tight to loosen by hand.

Pour the Haas Axis Lubrication Oil [A] into the reservoir to 1/2" (13 mm) below the threads on the reservoir.

Install the reservoir [B]. Use your hand to tighten it until the gasket makes contact with the reservoir head. Tighten another 3/4 turn.

Axis Lubrication System - Prime and Test

1

Press [DIAGNOSTICS].

Go to the Maintenance tab and navigate to the Lube tab.

Press [F2] to start the Axis Lubrication Test.

2

Perform the Axis Lubrication Test again until you no longer get axis lubrication alarms. Wait a minimum of (1) minute between Axis Lubrication Test cycles.

Check the level of the oil in the reservoir.

If the oil lines were nearly empty, it may be necessary to refill the axis lubrication reservoir after you purge the lines of air. Pour the oil into the reservoir to about 1/2" (13 mm) below the threads on the reservoir. 
 NOTE: If the machine has a C-axis, the C-axis gear lube hose must be disconnected from the lube panel manifold during the lubrication air purge process.

Haas Axis Lubrication Oil - Conversion

AD0629

Applies to machines built from April, 2014 to August 2022

Introduction

                 

Important: CHC Mills will need software M18.28 or higher and CHC Lathes will need software L11.24 or higher.
Service Techs performing the software update on CHC Mills should view this service news on the HSG site.

 Note: If your machine needs to upgrade to a metal reservoir from plastic, order kit 93-2601B and refer to the HLG Plastic to Metal Haas Axis Lube Oil (HALO) Reservoir - Conversion procedure.

This procedure will explain how to convert the axis lubrication system to Haas Axis Lubrication Oil on machines with Haas Liquid Grease.

Axis Lubrication Has Changed From Grease to Oil - Service Update

This procedure applies to the following service kits:

  • 93-3585: AXIS LUBE CONVERSION KIT HLG TO OIL
  • 93-3610: HALO SVC KIT CHECK VALVE

Note: Every Lathe will need at least one (1) of kit 93-3610. Lathes that also have a Y-Axis will need to order two (2) of kit 93-3610.

Note: UMC's will now need three (3) of kit 93-3610 to add check valves to all of the lubrication lines.

Important: Before ordering any check valves kits (93-3610) please verify the machines configuration in the images in the Install New Reservoir section below.

Before performing this procedure, verify the axis lubrication system is clear. This can be verified by running an Axis Lubrication Test in the Maintenance Tab. If Alarm 2082 is generated OR if the pressure has not gone back down in 1 hour, this is an indication that the axis lube lines are clogged.

If you need to purge axis lube lines refer to the following procedure: Haas Liquid Grease - Purge Clogged Lines. 
 NOTE: If the machine has a C-axis, the C-axis gear lube hose must be disconnected from the lube panel manifold during the lubrication air purge process.

Once the lines have been purged and the pump manifold cleaned, continue on to the rest of this procedure.

Install New Reservoir

1

Fill the new reservoir [1] with the Haas Axis Lubrication Oil to about 1/2" (13 mm) below the threads on the reservoir.

                       

2

Follow this step for Mills

Note: UMC's will now need three (3) of kit 93-3610 to add check valves to all of the lubrication lines, the check valves are grey in image [2] to show where they need to be added.

Mills with a SMTC will need to add a .02" orifice (shown as the red component in the images) to their lube lines on the oil reservoir. Use the numbered images and the following list to see where the orifice needs to be added on the following machines:

  1. SMTC: VF - 1-9, DT, DM, VR-8, VM - 2/3/6, VC-400
  2. UMC 350-1600
  3. EC-400/500/500-50T/630/630-50T
  4. GM-2, GM-2-5AX
  5. VF - 10/11/12/13/14, VR - 9/10/11/12/13/14
  6. VMT-750
  7. VS-1/3

Note: A small amount of SMTC's do not have a servo carousel and therefore will not need the additional orifice. This means that any mills that only have 3 grease lines on the lubrication reservoir do not need the additional orifice.

Note: Not all lubrication configurations are shown, only configurations that are adding new fittings in the conversion process are shown for reference on where the new fitting goes.

3

Follow this step for Lathes

Note: Every Lathe will need at least one (1) of kit 93-3610. Lathes that also have a Y-Axis will need to order two (2) of kit 93-3610.

 Note: Tail stock fittings are shown as the blue component in the images. 

Lathes with a C-Axis will need to add a .02" orifice (shown as the red component in the images) to their lube lines on the oil reservoir. Lathes will also need to add an extra check valve and nipple fitting to the X-Axis and the Y-Axis if it has one (the X and Y axes are labeled in the image to the right). Use the numbered images and the following list to see where the orifice and fittings need to be added on the following machines:

8. Longbed & Non-longbed: CL, ST-10/15/20/25/28/30/35

HLG Plastic to Metal Haas Axis Lube Oil (HALO) Reservoir - Conversion

AD0660

Introduction

                 

Important: CHC Mills will need software M18.28 or higher and CHC Lathes will need software L11.24 or higher.
Service Techs performing the software update on CHC Mills should view this service news on the HSG site.

This procedure will explain how to convert the HLG Plastic reservoir axis lubrication system to Haas Axis Lubrication Oil with the metal reservoir.

This procedure applies to the following service kits:

  • 93-2601B: AXIS LUBE RSRV METAL HAAS AXIS LUBE OIL
  • 93-3610: HALO SVC KIT CHECK VALVE

Note: Every Lathe will need at least one (1) of kit 93-3610. Lathes that also have a Y-Axis will need to order two (2) of kit 93-3610.

Note: UMC's will now need three (3) of kit 93-3610 to add check valves to all of the lubrication lines.

Important: Before ordering any check valves kits (93-3610) please verify the machines configuration in the images in the Install New Reservoir section below.

Before performing this procedure, verify the axis lubrication system is clear. This can be verified by running an Axis Lubrication Test in the Maintenance Tab. If Alarm 2082 is generated OR if the pressure has not gone back down in 1 hour, this is an indication that the axis lube lines are clogged.

If you need to purge axis lube lines refer to the following procedure: Haas Liquid Grease - Purge Clogged Lines. 

Once the lines have been purged and the pump manifold cleaned, continue on to the rest of this procedure.

Axis-Lubrication Reservoir Assembly- Replacement

1

Label the output grease hoses from the used axis-lubrication reservoir assembly so they can be put back in the same location when you are finished replacing the assembly.

Disconnect the input air hose and output grease hoses from the used axis-lubrication reservoir.

Remove the used axis-lubrication reservoir assembly from the cabinet.

Disconnect the pressure switch cable from the assembly.

Remove the air input fitting and the grease manifold fro the used axis-lubrication reservoir assembly.

2

Remove and discard the used 1/4" OD tube (same location as a new hose [2] shown in image) from the oil manifold [1].

Install the air input fitting [5] into the new axis-lubrication reservoir assembly [3]. Orient the top of the air input fitting parallel to the two screw bosses [4] on the new axis-lubrication reservoir [3]. 

Look at the bottom tip of the hose [5]. Verify:

  • The tip must be cut at 45 degrees.
  • It must clear the filter screen by approximately 1/16" (2mm).
  • If it is necessary to shorten the hose, cut it at the top.
    • Leave enough hose to make a good connection with the oil manifold [1].
    • Do not kink the hose.

Do not pull the new tube completely out of the port on the head. only pull the new 1/4" OD tube [2] one or two inches from the port on the head of the new axis-lubrication reservoir assembly that has the "OUT" label. Insert the tube until it is firmly seated in the fitting in the oil manifold [1].

Install the oil manifold [1] into the new axis-lubrication reservoir assembly [3]. The holes on top of the air input fitting [4] and oil manifold [1] must be aligned as shown [6].

3

Install the metal reservoir with oil [6]. Install the completed new axis-lubrication reservoir assembly into the cabinet.

Use the adapter bracket [1] if the holes in the cabinet do not match the holes in the head assembly. Make sure the bracket is oriented as shown. 

Note: Damage can occur over time if the vertical axis hose is not connected to an output with a check valve. Air can get into the hose and the vertical axis won't get adequate lubrication.

Connect the input air hose [5] and output grease hoses. Make sure to install the vertical axis to the output port with the check valve [3]. The other axes are installed on the hose fittings [4].

Connect the pressure switch cable to the pressure switch behind the oil manifold [2].

Install New Reservoir

1

Fill the new reservoir [1] with the Haas Axis Lubrication Oil to about 1/2" (13 mm) below the threads on the reservoir.

                       

2

Follow this step for Mills

Note: UMC's will now need three (3) of kit 93-3610 to add check valves to all of the lubrication lines, the check valves are grey in image [2] to show where they need to be added.

Mills with a SMTC will need to add a .02" orifice (shown as the red component in the images) to their lube lines on the oil reservoir. Use the numbered images and the following list to see where the orifice needs to be added on the following machines:

  1. SMTC: VF - 1-9, DT, DM, VR-8, VM - 2/3/6, VC-400
  2. UMC 350-1600
  3. EC-400/500/500-50T/630/630-50T
  4. GM-2, GM-2-5AX
  5. VF - 10/11/12/13/14, VR - 9/10/11/12/13/14
  6. VMT-750
  7. VS-1/3

Note: A small amount of SMTC's do not have a servo carousel and therefore will not need the additional orifice. This means that any mills that only have 3 grease lines on the lubrication reservoir do not need the additional orifice.

Note: Not all lubrication configurations are shown, only configurations that are adding new fittings in the conversion process are shown for reference on where the new fitting goes.

3

Follow this step for Lathes

Note: Every Lathe will need at least one (1) of kit 93-3610. Lathes that also have a Y-Axis will need to order two (2) of kit 93-3610.

 Note: Tail stock fittings are shown as the blue component in the images. 

Lathes with a C-Axis will need to add a .02" orifice (shown as the red component in the images) to their lube lines on the oil reservoir. Lathes will also need to add an extra check valve and nipple fitting to the X-Axis and the Y-Axis if it has one (the X and Y axes are labeled in the image to the right). Use the numbered images and the following list to see where the orifice and fittings need to be added on the following machines:

8. Longbed & Non-longbed: CL, ST-10/15/20/25/28/30/35

9. Y-Axis Longbed & Non-longbed: ST-10Y/ 15Y/20Y/25Y/28Y/30Y/35Y, ST-10LY/15LY/20LY/25LY/28LY/30LY/35LY

10. C-Axis Longbed & Non-longbed: ST-10/ 15/20/25/28/30/35

11. C-Axis & Y-Axis Longbed & Non-longbed: ST-10Y/ 15Y/20Y/25Y/30Y/35Y

12. Longbed & C-Axis & Y-Axis & Sub-Spindle: DS-30Y, ST-10LY/ 15LY/20LY/25LY/28LY/30LY/35LY

13. Longbed & Tail Stock: ST-40/40L/45/45L/50/55

14. Longbed & C-Axis & Tail Stock: ST-40/45/50/55

15. Longbed/Non-Longbed & Tail Stock: ST-30/35

16. Longbed/Non-Longbed & Tail Stock & Y-Axis: ST-30Y/35Y

Note: Not all lubrication configurations are shown, only configurations that are adding new fittings in the conversion process are shown for reference on where the new fitting goes.

System Operation Overview

The Haas Axis lubrication Oil system utilizes shop air pressure to pressurize the HALO reservoir via a 120VAC solenoid. Both components are located inside the air/lube cabinet

The lubrication cycle will be initiated when:

  1. The axes have been in motion for the time specified in Setting 277 (3 hours by default).
  2. The machine has been idle for 12 hours (specified in Parameter 1401).
  3. If the user presses [F2] while in the LUBE MAINTENANCE section of the DIAGNOSTIC display.

The HALO manifold has two internal check valves [1] and [2]; internal snubber before the check valve [2]; the pressure gauge and the 4 PSI normally open pressure switch [3]. There are multiple lubrication lines coming out of the HALO manifold depending on the machine type and configuration. The lubrication lines that are routed above the air/oil pump will have a check valve [4] at the HALO manifold to prevent the oil from draining from the lines back to the reservoir between the lubrication cycles.

When a lubrication cycle is commanded, the solenoid applies air pressure to the HALO reservoir for 3 seconds (specified in Parameter 2027), which forces the oil to move up the pick-up tube [5] and into the HALO manifold. The oil flows through the lubrication lines to the lubrication points where it gets pushed through the restrictors into the components that require the lubrication (ballscrew, linear guides pads, etc). Once the cycle ends, the pressure from the HALO reservoir is vented to the atmosphere, the check valve [1] traps the pressurized oil in the manifold and it will start to flow through the snubber and the check valve [2] back to the HALO canister until the pressure in the manifold drops to 0 PSI.

During the lubrication cycle the control monitors the pressure in the lubrication manifold in order to detect a failure of the lubrication system.

When the solenoid is commanded to turn on, the control begins to monitor the status of the pressure switch [3]. The switch is expected to close within 3 seconds (specified in Parameter 1374) from the moment that the solenoid was commanded ON. Once the pressure is detected it is expected to stay for at least 15 seconds (specified in Parameter 1375). If all of the above statements were satisfied during the cycle then the lubrication cycle is considered successful.

If pressure in the system was not detected within 3 seconds (specified in the Parameter 1374) the control will stop monitoring the pressure and display the “Low Lube” warning icon until the next lube cycle. If such a condition was detected for 5 consecutive lube cycles, then the control will generate the Alarm 2073 AXIS LUBRICATION PRESSURE NOT DETECTED. The alarm will not be generated during a program execution, it will only be generated after the program execution ends or after pressing a [RESET] button.

If the pressure in the system drops below 4 PSI before 15 seconds (specified in Parameter 1375), the control will display “Low Lube” warning icon until the next lube cycle. If such a condition is detected for the next 4 consecutive lube cycles (5 total cycles) the control will generate the Alarm 2075 AXIS LUBRICATION RESERVOIR IS EMPTY. The alarm will not be generated during a program execution. It will be generated after the program execution ends or after pressing a [RESET] button.

Low Lube Icon

 When the axis lube solenoid was commanded the system never detected pressure or the pressure duration was too short. Inspect the reservoir assembly and make sure the check valves are not stuck or sticking. Also refer to the Check Valve O-rings section below to verify the o-rings are seated properly.
Alarm 2075 AXIS LUBRICATION RESERVOIR EMPTY Air in axis lubrication line. The reason for the air in the lines needs to be identified and corrected. See the ALARM 2075: AXIS LUBRICATION RESERVIOR EMPTY section.
The check valves may be sticking and causing excessive oil usage. Inspect the reservoir assembly and make sure the check valves are not stuck or sticking. Also refer to the Check Valve O-rings section below to verify the o-rings are seated properly.
There may be debris in the HALO manifold and/or in front of the pressure sensor. Clean out the HALO manifold and clean around the pressure switch.
There may be air in the lube lines. Prime the lube lines and make sure no air is leaking from the HALO manifold when the system is pressurized.
Lathes do not have an added check valve on their x-axis and y-axis (if applicable) lubrication lines. Verify the lathe has the correct amount of check valves on its lubrication lines, the configurations can be seen below in the HALO Lubrication Lines Configurations section.
UMC's do not have the added check valves to their lubrication lines. Verify the UMC has the correct amount of check valves on its lubrication lines, the configurations can be seen below in the HALO Lubrication Lines Configurations section.
The correct configuration of check valves needed may not be installed in the HALO manifold. Verify the correct amount of check valves are on the lubrication lines, the configurations can be seen below in the HALO Lubrication Lines Configurations section.
Alarm 2073 AXIS LUBRICATIONPRESSURE NOT DETECTED Solenoid not supplying air to HALO system. See solemoid troubleshooting section in the Alarm 2075 section below.
Pressure switch not changing states. See section 4-5 of the Alarm 2075 troubleshooting guide
When refilling the oil reservoir, the filter is found to be crushed at the bottom. The pressure in the oil reservoir can cause the bottom of the filter to crush. A new filter that is reinforced has been created and can replace the old crushed filter. Order part number 58-2072A to replace a crushed filter.

HALO Lubrication Lines Configurations

                       

Mill Lubrication Lines

Note: UMC's will now need three (3) of kit 93-3610 to add check valves to all of the lubrication lines, the check valves are grey in image [2] to show where they need to be added.

Mills with a SMTC will need to add a .02" orifice (shown as the red component in the images) to their lube lines on the oil reservoir. Use the numbered images and the following list to see where the orifice needs to be added on the following machines:

  1. SMTC: VF - 1-9, DT, DM, VR-8, VM - 2/3/6, VC-400
  2. UMC 350-1600
  3. EC-400/500/500-50T/630/630-50T
  4. GM-2, GM-2-5AX
  5. VF - 10/11/12/13/14, VR - 9/10/11/12/13/14
  6. VMT-750
  7. VS-1/3

Note: A small amount of SMTC's do not have a servo carousel and therefore will not need the additional orifice. This means that any mills that only have 3 oil lines on the lubrication reservoir do not need the additional orifice.

Note: Not all lubrication configurations are shown, only configurations that are adding new fittings in the conversion process are shown for reference on where the new fitting goes.

Lathe Lubrication Lines

Note: Every Lathe will need at least one (1) of kit 93-3610. Lathes that also have a Y-Axis will need to order two (2) of kit 93-3610.

 Note: Tail stock fittings are shown as the blue component in the images. 

Lathes with a C-Axis will need to add a .02" orifice (shown as the red component in the images) to their lube lines on the oil reservoir. Lathes will also need to add an extra check valve and nipple fitting to the X-Axis and the Y-Axis if it has one (the X and Y axes are labeled in the image to the right). Use the numbered images and the following list to see where the orifice and fittings need to be added on the following machines:

8. Longbed & Non-longbed: CL, ST-10/15/20/25/28/30/35

9. Y-Axis Longbed & Non-longbed: ST-10Y/ 15Y/20Y/25Y/28Y/30Y/35Y, ST-10LY/15LY/20LY/25LY/28LY/30LY/35LY

10. C-Axis Longbed & Non-longbed: ST-10/ 15/20/25/28/30/35

11. C-Axis & Y-Axis Longbed & Non-longbed: ST-10Y/ 15Y/20Y/25Y/30Y/35Y

12. Longbed & C-Axis & Y-Axis & Sub-Spindle: DS-30Y, ST-10LY/ 15LY/20LY/25LY/28LY/30LY/35LY

13. Longbed & Tail Stock: ST-40/40L/45/45L/50/55

14. Longbed & C-Axis & Tail Stock: ST-40/45/50/55

15. Longbed/Non-Longbed & Tail Stock: ST-30/35

16. Longbed/Non-Longbed & Tail Stock & Y-Axis: ST-30Y/35Y

Note: Not all lubrication configurations are shown, only configurations that are adding new fittings in the conversion process are shown for reference on where the new fitting goes.

ALARM 2075: AXIS LUBRICATION RESERVIOR EMPTY

 Note: The specification for Haas Axis Lubrication Oil changed as of 2/2025. It is highly reccommended that HALO systems be converted to the current standard to prevent alarm 2075.

Lubricant, Grease, and Sealant Tables for Haas Machine Components

OIL REFILL, AXIS LUBE OIL - 1 GL / 3.78 L

1

Verify that the oil reservoir [A] is full.

Verify the machine is getting correct air pressure on the gauge [7], and on the gauges page on the Haas control.

Verify that air is being delivered to the HALO manifold [1 & 2] by manually triggering the solenoid. 

Verify that there are no leaks on the air line [5] between the solenoid and the HALO manifold.

Verify that the solenoid [6] works properly. Remove the air line [5] from the HALO manifold and run an axis lubrication cycle. 

   DIAGNOSTIC > MAINTENCANCE > LUBE    

 Note: If your machine has had an upgrade from the Haas liquid Grease (HLG) to the Haas Axis Lubrication Oil (HALO) then you must ensure you also apply the relating patch which modifies lubrication parameters.

Axis Lubrication Has Changed From Grease to Oil

 Note: Monthly maintenance procedures state that the axis lubrication oil should be checked once a month. Neglecting the alarm can cause air to be introduced into the lines affecting the function of the system.

SOLENOID TROUBLESHOOTING

2

Inspect the axis-lube air solenoid.

Do the Axis Lubrication Test and make sure the voltage to the HALO solenoid is 120 VAC.

 Note: Do not measure the voltage with the HALO solenoid disconnected from the connector.

Refer to the I/O PCB - Troubleshooting Guide (Classic Haas Control) to troubleshoot the I/O PCB.

Refer to the Solenoid Troubleshooting Guide to troubleshoot the solenoid.

If the solenoid is not activating when commanded, check for:

  • The connector being in the correct location.
  • Loose or broken wires.
  • Air coming out of the solenoid without the tube connected.
  • Firm solenoid cable connection at the I/O board.

3

Verify that the manifold is configured properly, reference the HALO LUBRICATION LINES CONFIGURATIONS section above.

Verify that the HALO manifold and reservoir [2] are not leaking. 

Verify that all lines are properly secured into their push connect fittings [1] and that the threaded fittings are fastened tightly.

 Note: Vertical axes and SMTC lines will likely include check valves.

4

Check the states on the I/O tab for the solenoid output and the pressure gauge input. 

Run the axis lubrication cycle.

    DIAGNOSTIC > MAINTENCANCE > LUBE  

Observe the value changes in the I/O tab while the cycle takes place to verify the bits are changing.

  • The pressure gauge input should change from a 1 to 0 and back to 1 during the cycle.
  • The  solenoid output should change from a 0 to 1 and back to 0 during the cycle.
NAME P# TYPE SW# HW# CONNECTOR INITIAL VALUE
LOW_AXIS_GREASE_PRESSURE P48 INPUT 24 IO20 P48.47 1
AXIS_GREASE_PUMP P17, P15 OUTPUT 68 O003 P35.2, P17.2 0

PRESSURE SWITCH TROUBLESHOOTING

5

If the LOW_AXIS_GREASE_PRESSURE input does not change states.

 Note: For NGC check the software version on the machine. The machine must have software version 100.16.000.1020 or higher. Update the machine software if necessary.

Disconnect the cables from the pressure switch and use a jumper to connect them as shown. The pressure switch is behind the grease manifold

  • If the input changes from a 1 to a 0, the pressure switch is working properly.

Measure continuity from the IO board to the switch.

  • If there is no continuity then the cable may be bad.

Measure the resistance across the the pressure switch terminals while running the lube cycle.

  • If the resistance reads 'OL' then measures a value of resistance then reads 'OL' again the pressure switch is working properly. If it does not then the pressure switch may be faulty.

MANIFOLD TROUBLESHOOTING

6

Remove all oil lines and plug all ports [1] on the HALO manifold and activate the lube cycle.

    DIAGNOSTIC > MAINTENCANCE > LUBE  

If the pressure drop at the HALO manifold gauge [2] is less than 15 seconds it will generate the low lube icon, this indicates that there is a leak in manifold and requires further troubleshooting.

If the manifold holds pressure for longer than 15 seconds and no icon shows on the monitor, it is working as intended, and the rest of the system needs to be troubleshot.

7

If the HALO manifold pressure falls rapidly remove and check the condition of the manifold's check valves [1 & 2] located at the top and bottom.

Inspect the assembly and make sure the check valves are not stuck or sticking. Clean and replace where necessary.

Check for air and oil leaks around all connections and ports.

LUBRICATION LINE TROUBLESHOOTING

8

To test for a failed line that is leaking:

  • Choose one non-check valve port to test with [1]. For UMC machines a push connect fitting can be installed on one of the unused ports [4] at the bottom of the HALO manifold.
  • Remove and mark the position of the oil lines.
  • Plug all ports except the chosen non-check valve port [2] on the HALO manifold.
  • Pick a line to test and connect it into the chosen non-check valve port. Manually actuate the solenoid for 10 seconds and wait for the pressure guage to drop to zero psi. Repeat this step until the line holds for longer than 15 seconds.
  • Activate the axis lubrication cycle with the chosen line to determine if the system will generate low reservoir icon or the 2075 alarm.

  Run the axis lubrication cycle.

        DIAGNOSTIC > MAINTENCANCE > LUBE

  • If the machine generates the 2075 alarm or Low lube icon message, this can indicate that the system is not fully purged. Continue manual actuation of the solenoid. 
  • If the pressure is consistently dropping rapidly this indicates an issue down the line and it needs to be fully troubleshot.
  • If it does not generate the alarm or the low lube icon message move on to the next line, removing the previously tested line from the chosen non-check valve port and plugging the new line into that same port.

Repeat this process for all oil lines connected to the HALO manifold until the lines which generate the alarm or icon have been identified. 

9

If the alarm is generated on a single axis this may indicate that this line is causing the alarm.

The assembly being fed by this line must then be examined.

If the line has a check valve at the HALO manifold, verify that it is in working condition.

To verify if a linear axis has a leak or not, the axis oil manifold and its connections to the trucks and ball nut must be observed.

Clean these components and run the lubrication cycle looking for leaks.

PRIMING THE HALO SYSTEM

10

If no leaks are found after troubleshooting the HALO manifold and the axis oil lines, perform the following steps.

 Note: An empty HALO reservoir is the most common way to introduce air into the lines. 

Reconnect all lines to the HALO manifold and verify the reservoir is full.

To purge the system:

  • Gain access the axis oil manifolds [3] and the tool changer port. C-axis port for lathes.
  • Remove an axis line [2] individually from an axis oil manifold [3] at the barb fitting.
  • Manually actuate the lubrication solenoid until the line is individually purged of air. Air trapped in the middle of the lines is a large concern.

 Note: If the reservoir runs empty during this step air will be introduced into the system and the step will have to be repeated. Large machines will be more vulnerable to this case.

  • Reinstall the primed line onto the axis manifold [3].
  • Manually actuate the lubrication solenoid five times for 10 seconds at 15 second intervals to purge the axis lube assembly.
  • Refill the oil reservoir [1] if needed.

Activate the axis lubrication cycle to determine if the system will generate low reservoir icon or the 2075 alarm.

                        DIAGNOSTIC > MAINTENCANCE > LUBE

  • Repeat for all lines.

 Note: Observing the mill or lathe maintenance schedule will reduce the risk of air intrusion. An empty HALO reservoir is the most common way to introduce air into the lines.
