4.
Rotate the spindle by hand. The runout should be less than 4µm (0.004mm). Reposition the
pin to minimize the runout before attempting to adjust the chuck. Make sure to only rotate
the pin in one direction to minimize indicator backlash.
5.
If the chuck requires adjustment, remove the tool spindle chuck cover to expose the four
mounting bolts and four jack screws. Carefully loosen the four mounting bolts and
jackscrews until they are all just snug.
6.
Carefully tap the chuck with a brass mallet or use the jack screws to minimize the runout
reading on the pin to within 2µm.
7.
Tighten mounting bolts. Use caution to minimize any bolt-induced runout. Reinstall the
chuck cover.

Check and adjust the runout of the lower chuck using only the mount bolts (without the
