Operation setup
P/N 63674, Rev. 9 Page 55
Since the milling head is mounted on a center pivot, the angle of the milling head
must be aligned before machining can begin. This adjustment is made using the
adjustment screws in the blocks mounted either below or above the housing. The
rotational adjustment screws allow the housing to be rotated slightly to achieve
vertical or horizontal orientation relative to the machining arm.
Do the following to adjust the
milling head and spindle:
1. Loosen the lock.
2. Adjust the milling head
and spindle.
3. Use the DRO to position
the milling head.
4. Tighten the lock before
machining.
4.1.3 Spindle tramming
Spindle tramming is the process of orienting the spindle.
The spindle must be oriented perpendicular to the machine tool itself
rather than to the workpiece, which is not a reliable reference point.
Do the following to tram the spindle:
1. If the spindle drive motor is installed, remove it from the spindle gearbox
to allow easy hand-rotation of the spindle.
