CNC Spindle Alignment, Shims, and Vibration

The shims are just used to align the spindle perpendicular to the table. It’s pretty unlikely without at least one shim. If you are not sure how to tram the spindle, call the manufacturer. It really isn''t that hard once you have done it once or twice. My main concern is the evidence of vibration in terms of runout.

Troubleshooting Spindle Problems

For warm-up, run the spindle at 9,000 rpm for 10-15 minutes or until the spindle bearing supports reach 98º F (human body temperature). This allows bearings, bearing supports and the spindle shaft to reach their designed dimensions and preloads through thermal expansion. Applying loads to a cold spindle will cause premature bearing failure.
