Change of bearing on Mazak main spindle

Spindle repair

Before christmas, we received a Mazak VTC 200 iso 40 12000 rpm main spindle from Norway.

The spindle is taken apart and cleaned, to be able to know if everything is okay, when the spindle is measured in our bearing lab.

In the bearing lab the spindle axis is measured, and the rings are grinded for parallelism.

The work demands precision, and the rings are measured again, including between the rings, the house and front cover for correct spread.

The main spindle gets new spare parts:

  • New plate spring
  • New middle tube constructed
  • New bearings and O-rings mounted

All parts are assembled and mounted, and to make sure everything is in place, we do a test run of the spindle.
