This procedure determines the distance between the plane of the rotary axis platter and the tilt axis centerline on tilting rotary products. Some CAM software applications require this offset value. You also need this value to rough-set the MRZP offsets. Refer to page UMC Set MRZP Offsets for more information.

Tilt Axis Center-of-Rotation Illustrated Procedure. Numeric labels in this diagram correspond to the step numbers in the procedure.

  1. Jog the tilt axis until the rotary platter is vertical. Attach a dial indicator to the machine spindle (or other surface independent of table motion) and indicate the platter face. Set the dial indicator to zero.
    note: The rotary unit’s orientation on the table determines which linear axis to jog in these steps. If the tilt axis is parallel to the X Axis, use the Y Axis in these steps. If the tilt axis is parallel to the Y Axis, use the X Axis in these steps.
  2. Set the X- or Y-Axis operator position to zero.
  3. Jog the tilt Axis 180 degrees.
  4. Indicate the platter face from the same direction as the first indication: Hold a 1-2-3 block against the platter face. Indicate the face of the block that rests against the platter face. Jog the X or Y Axis to zero the indicator against the block.
  5. Read the new X- or Y-Axis operator position. Divide this value by 2 to determine the tilt axis center-of-rotation offset value.

Be aware: Many service and repair procedures should be done only by authorized personnel. The service technicians at your Haas Factory Outlet (HFO) have the training, experience, and are certified to do these tasks safely and correctly. You should not do machine repair or service procedures unless you are qualified and knowledgeable about the processes.

Danger: Some service procedures can be dangerous or life-threatening. DO NOT attempt a procedure that you do not completely understand. Contact your Haas Factory Outlet (HFO) and schedule a service technician visit if you have any doubts about doing a procedure.
