Warning

Please fill out the latest Inspection Report on HBC and consult with Haas Service before attempting any geometry adjustments.

 Note: This site is available only to Haas Service Techs.

 WARNING: Breaking the DON'T REMOVE seal on the spindle without contacting Haas Service will VOID the warranty. Contact Haas Service before proceeding with process.

WARNING: This page may be used as reference for the inspection report but do not make any adjustments before consulting with Haas Service. Adjustments made without consulting Haas Service will void warranty.

Inspection Report

Introduction

 Note: This procedure applies to the Double Yoke machine. Follow the H-5AX Single Yoke Spindle Head - Geometry Guide for the VR Single Yoke machines.
 
This procedure will go over how to adjust the following components on the VR-series machine:
 
  1. Haas 5-Axis Head
  2. Spindle Head
  3. Column
  4. Base
  5. Saddle
  6. Table

Note: As mentioned before this procedure can be used as an aid to the inspection report, but adjustments made without consultation from Haas Service will void warranty for the machine. 

Leveling

Verify the level, if the machine is not level follow the instructions below to level the machine. 

1

  • Adjust the four corner leveling screws to the same height to lift the base casting to the height specified as [H] on the leveling decal on the back of the machine.
  • Loosen the middle leveling screws [3, 6] so that they are not touching the pads, install jam nuts [1] on leveling screws, but do not tighten 
  • Jog the table so that it is centered in the machine. 

2

  • Place the level on the center of the bed and position it so that the shorter vial is parallel to the Y-axis and the longer vial is parallel to the X-axis.
  • Using the shorter vial adjust the front to back level by either adjusting the front or back leveling screws.
  • Adjust the leveling screws until the Y-axis bubble is centered. 
  • Using the longer vial which is parallel to the X-axis, raise the leveling screws on lower side of the machine.
  • Adjust the leveling screws accordingly until the X-axis bubble is centered

3

  • Continue using the longer vial, with the table at the front of the machine look at the position of the indicating bubble
  • Jog the table through its full Y-axis travel stopping at the column, with the table at the column look to see which rear corner of the machine is lowest if any. 
  • If needed adjust the leveling screws 2 and 4 until there is no twist across Y axis
  • Continue adjusting the level at the front and back of the machine until both readings are zero.
  • Lower the center leveling screws 3 and 6 until they make contact with the pads. Tighten these hand tight and then tighten them an additional 10 degrees with the ratchet. 

4

  • Place the level in the center of the bed and orient it so the long vial is parallel to the Y-axis
  • Look at the bubble position when the bed is at its center position and then jog the bed back in the Y direction until it reaches the column.
  • Take note of the bubble position, if the level shows that the machine is either bowed in the up or down direction, make small and even adjustments to middle leveling screws 3 and 6
  • The Tolerance for both the twist and bow is N.T.E 0.0002"/10"

For a more in depth guide on how to level your VMC including how to level machines with outriggers please see:

VMC Leveling

Flatness of Square Granite

Place three leveling jacks on the VR table then place a 12 inch (305mm) square granite on the leveling jacks.

Adjust the surface of the granite flat. This is NTE 0.0001"

X-Axis to Y-Axis Perpendicularity

With the granite adjusted flat, place the indicator on the front face of the granite [1]. Zero the indicator and run it across the granite, adjust the granite so that both ends read zero.

Once the X-axis plane is zeroed. Place the indicator on one of the sides of the granite [2]. Parallel to the Y-axis plane. Zero the indicator on one end of the granite and run the indicator to the opposite end of the granite. Record the measurement. 

This measurement is NTE 0.0005/10"

Note: The X-Axis and Y-Axis waycovers will need to be disconnected from the saddle to gain access to the bolts.

To adjust the Y-Axis perpendicular to X-Axis loosen the five bolts connecting the Y-Axis Ballnut to the Ballnut housing, and the ten bolts that connect the Ballnut housing to the saddle. 

Loosen the hardware [1] on the front of the saddle that connects the casting [2] to the linear pads. Be sure to loosen all 4 pads.

NOTE: There is hardware [3] for each linear pad found under the table that needs to be loosen as well to make this adjustment. This hardware can be either SHCS or studs.

Once the bolts for all 4 linear pads are loosened, jog the saddle front to back a few times. Tap the saddle to make adjustments if needed.

Once the perpendicularity is within spec, tighten and torque all bolts back to specification using the HAAS TORQUE SPECIFICATION and re-check the X-Y perpendicularity.

WARNING: This step may be used as reference for the inspection report but do not make any adjustments before consulting with Haas Service. Adjustments made without consulting Haas Service will void warranty.

X-Z plane & Y-Z Plane Perpendicularity

1

Place a cylinder on the granite and place an indicator on the top face of the granite [1]. Adjust the cylinder flatness so that the indicator reads zero in X/Y motion by shimming under the cylinder.

Place the indicator on the back face of the cylinder [2], zero the indicator, and jog the Z-axis up and down. This measurement is NTE 0.0005/10".

Place the indicator on the side face of the cylinder [3], zero the indicator, and jog the Z-axis up and down. This measurement is NTE 0.0005/10". 

2

IMPORTANT: This step is for reference only.  The column should not need to be adjusted, as the head geometry may influence this value. If any adjustments need to be made Haas service approval is  necessary. Adjustments made without consulting Haas Service will void warranty.

To adjust perpendicularity in either plane place shims on the highlighted portion of the riser block [1].

The shim amount should not exceed 0.008" thickness.

C-Axis Parallel to Z-Axis

1

Place an indicator on the B-Axis body and place the indicator on the face of the granite, set up the indicator so that it can sweep the granite with a 10" diameter.

Zero the indicator and rotate the C-Axis 360 degrees and record the measurement. This measurement is NTE 0.0008/10" diameter.

 Note: You will not be able to fully rotate 360 degrees in one direction as the head has +245 to -245 travel limits.

Then place the indicator on the front face and zero the indicator 4 inches away from the face of the spindle [2]. It is recommended to mark a point on the test bar to indicate the spot to take measurements on the next portion of the test. 

On the operators page, set the Y, Z, and B-Axis to zero. 

3

 Note: This test will move the B-Axis in 45 degree increments and creates a plane that will be evaluated.

The starting position will be at B = +90 shown in the previous step, this will always be our zero. 

Jog the B-Axis to B = +45.

Jog the table to move the indicator to the position that was marked on the test bar. Make sure to jog in the Z and X direction to find the "high" value in the B = +45 position. Record the value.

 Note: It is recommended to use a dual dial test indicator.

Jog the B-Axis to B = 0, B = -45, and B = -90 position, all while jogging the table to move the indicator to the marked position on the test bar in each of the B-Axis movements and record the values. Find the "high" spot in each of these positions to take the measurement. 

 Note: It is recommended to not move the Y-Axis during this test, but if it is moved return it to the operators Y-Axis zero position.

Jog the B-Axis to B = -90. 

Then place the indicator on the front face and zero the indicator 4 inches away from the face of the spindle. It is recommended to mark a point on the test bar to indicate the spot to take measurements on the next portion of the test. 

Redo the sweep steps mentioned in the previous step and record the values. The difference between the measurements in run 1 and run 2 at each B-Axis position divided by 2, is NTE 0.004" (Run 1 is at C = 0, Run 2 is at C = 180; use latest inspection report to help calculate).

Inspection Report

Spindle Centerline Parallel to C-Axis

1

Home the B and C-Axis, mount the indicator on the spindle nose and set the indicator to sweep a 10" diameter circle. Set the indicator to zero at position [1] and sweep to position [2]. This is NTE 0.0005"

Record the measurement and fix this by adjusting the B-Axis Tool Change Offset. See the B-Axis Tool Change Offset steps.

Note: The B-Axis Tool Change Offset must be set before moving on to sweeping positions [3] and [4].

2

Set the indicator to zero at position [3] and sweep a 10" diameter circle to position [4] and record the measurement, this is NTE 0.002".

3

Repeat the same steps above with the C-Axis at C = +90.

Set the indicator to zero at position [1] and sweep to position [2]. 

Record the measurement.

Set the indicator to zero at position [3]. Sweep to position [4] and record the measurement.

 Note: This check is to make sure the C-Axis is parallel to Z-Axis. You should see the same error when C = 0 and when C = +90. Any additional error is from the C-Axis parallel to Z-Axis step.

C-Axis Runout

1

Home the B and C-Axis and place an indicator on the test bar 4 inches away from the spindle face. Find the high spot on the test bar by jogging the indicator along the X-Axis.

 Note: Hold the test bar when jogging the C-Axis. 

Zero the indicator on the high spot and rotate the C- Axis +180/-180 degree's. Record the error at the following positions: C = +90, C = +180/-180, C = -90.

The error between C = 0 and C = +180/-180 is NTE 0.005" TIR. 

The error between C = -90 and C = +90 is NTE 0.005" TIR.

 Note: You will not be able to fully rotate 360 degrees in one direction as the head has +245 to -245 travel limits. 

Make a note of the C-Axis positions where the runout was the highest as this will be needed to make the adjustment.

Spindle Centerline and B-axis Intersection

1

Home the B and C-Axis.

In MDI command the B-Axis to -90°.

Place an indicator on the front face of the test bar at the end of the bar [1] on the high spot. Zero the indicator at this location.

Jog the Z-Axis up so the test bar clears the table and command B = +90°. Jog the table in the Z and X direction to move the indicator to position [2] on the front face of the test bar at the end of the bar on the high spot. Adjust the C-Axis so that the error on the indicator is the same between positions [1] and [2]. This should not exceed 0.0005".

 Note: Do not move the Y-Axis during this step.

2

Place the indicator on the bottom face [1] of the test bar and sweep the whole travel. Make sure this is straight, if not, adjust the B-Axis until it is. 

On the operators page, set the Y, Z, and B-Axis to zero. 

3

 Note: It is recommended to use a dual dial test indicator.

Rotate the B-Axis 180 degrees to B = -90 and jog the table to set the indicator on the bottom side of the test bar. 

It is recommended to not move the Y-Axis and only the X and Z. Jog the Z down to the zero position on the operators page. Sweep the bottom length of the test bar to make sure the error reads the same across the test bar. If it does not, adjust the B-Axis until it does. DO NOT MOVE THE Z-AXIS while making the adjustments, only the B-Axis. Divide the error by two. This is NTE 0.002".

If error exceeds tolerance contact Haas Service.
