How to adjust the spindle of CNC centering machine

　The spindle of CNC centering machine has a radial runout because the front bearing clearance is too large, while the axial runout is caused by the rear bearing clearance is too large. The front and rear bearings are tapered stick bearings, so they can adjust the clearance. When the clearance occurs, first loosen the tightening screw of the bearing nut, roll the clearance adjustment nut, make the inner ring of the rolling bearing with taper move along the axial direction, in addition to the clearance. Then test spin, when the spindle at high speeds without the onset of overheating, rolling by hand without a sense of stagnation, and then tighten the set screw will be able to!
