X-axis Roll

• First attach tool T-2192 to the side of the spindle.

• For X-Roll measurement hold the following Y and Z-axis postitions:
  • UMC 500 (Y,Z): -8, -8
  • UMC 750 (Y,Z): -10, -10
  • UMC 1000 (Y,Z): -12, -12

• Measure X-axis roll (NTE 0.0005" / 10")

B-axis to Y-axis Parallelism

• Zero-Return B and C-axis.

• Measure the platter runnout in the Y-Axis (NTE: 0.0008" / 10"; 0.0012" / 15")

• Then measure this same surface with the B-Axis at both -90° and +90°  (NTE: 0.0008" / 10"; 0.0012" / 15")

• For UMC 500 and 750, measure the full length of the platter

• For UMC 1000, offset 2” from edge of platter then measure across 20”

Y-axis to X-axis Perpendicularity

• Use jacking screws to make the top surface of the granite parallel to XY plane (NTE: 0.0002")

• Next, check if Y square to X (NTE 0.0005" / 10")

Perpendicularity of X-axis to Z-axis

• Place granite and precision cylinder on platter in the orientation shown

• Use jacking screws to set top surface of cylinder parallel to XY-Plane (NTE 0.0002")

• XY Spindle locations for this step:
  • UMC 500, X = -6, Y = -8
  • UMC 750, X = -10, Y = -10
  • UMC 1000, X = -17, Y = -12

• Z start position for this measurement:
  • UMC 500, Z_start = Z_top – 2”
  • UMC 750, Z_start = Z_top – 5”
  • UMC 1000, Z_start = Z_top – 7”

• Z_top is the limit of Z-axis travel in the positive direction (up)

• From Z_start, measure down 10” along cylinder

Perpendicularity of Y-axis to Z-axis

• Place granite and precision cylinder on platter in the orientation shown

• Use jacking screws to set top surface of cylinder parallel to XY-Plane (NTE 0.0002")

• XY Spindle locations for this step:
  • UMC 500, X = -6, Y = -8
  • UMC 750, X = -10, Y = -10
  • UMC 1000, X = -17, Y = -12
• Z start position for this measurement:
  • UMC 500, Zstart = Ztop – 2”
  • UMC 750, Zstart = Ztop – 5”
  • UMC 1000, Zstart = Ztop – 7”

• Ztop is the limit of Z-axis travel in the positive direction (up)

• From Zstart, measure down 10” along cylinder

C-Axis Perpendicularity to XY Plane

• Reposition the mag base on the spindle so it cannot rotate with the spindle.
• Place precision guage block at the edge of the platter in the 12 o'clock position. 
• Zero the indicator tip on the gauge block in this position.
• Rotate the C-axis  90° 
• Next, jog the spindle in the X and Y-axis to follow the guage block and take a measurement of the same point on the platter. No rotation of the spindle should occur
• Repeat this 2 more times for a total of 4 positions, 90° apart, at the edge of the pallet as shown. 
• The difference between 12 and 6 o'clock position measurements determines flatness along the X-Axis (NTE 0.0005")
• The difference between 3 and 9 o'clock position mesurements determines flatness along the Y-Axis (NTE 0.0005")

Platter Face Runout

NOTE: C-Axis brake is off for this step

• Place precision guage block at the edge of the platter in the 12 o'clock position. 

• Zero the indicator tip on the gauge block in this position.

• Rotate the C-axis  90° but, keep the guage block at the 12 o'clock position

• Take a measurement from the top of the gauge block

• Repeat this 2 more times for a total of 4 positions, 90° apart, at the edge of the pallet as shown. 

• Note the total indicated runout. (NTE 0.001")

Parallelism of Platter Surface to XY plane

• Zero-Return the C-axis so the T-slots run parallel to the X-axis

• Place indicator tip on the platter and jog in the X-axis along the platter to find the X-axis platter parallelism (NTE 0.001” / 10"; 0.0015" / 15")

• Next jog in the Y-axis along the platter to find the Y-axis platter parallelism (NTE 0.001” / 10"; 0.0015" / 15")

Spindle Runout

• Center the spindle over the C-Axis bore.

• Place the mag base on table and insert test bar.

• Check spindle runout at base of test bar (NTE 0.0005" TIR)

• Check spindle runout 6" down from the base of the test bar (NTE 0.001" TIR)

Spindle Centerline Parallelism to Z-axis

• Use jacking screws to make granite parallel to XY plane in the orientation shown (NTE: 0.0002")

• Center the spindle over the C-axis platter bore

• Sweep in a 10" diameter circle

• Record XZ TIR  (NTE 0.0005")

• Record YZ TIR  (NTE 0.0005")

Concentricity of C-Axis Bore

• Place indicator as show and jog C-axis 360°
• Record TIR of precision bore (NTE 0.002")

Machine Rotary Zero Point

• Use the VQC Macro Program and probe system to verify the values for the Coldfire parameters or the NGC settings shown below:
  • 255 - MRZP X OFFSET
  • 256 - MRZP Y OFFSET
  • 257 - MRZP Z OFFSET
  • 254 - 5 AXIS ROTARY CENTER POINT DISTANCE
