Mazak VTC200B Spindle Repair

Mazak VTC200B
12,000 rpm
40 taper
Oil Mist Lubrication
This customer has multiple Mazak VTC200B machines in their facility that were experiencing frequent spindle failures. We disassembled the first spindle and found that the design was very poor. The nut for the rear bearings was hydraulic and had the long shaft that attaches to the drive motor bolted to it. The problem with this setup occurs if there is any misalignment with the drive motor, any vibration in the drive motor or if any number of ground surfaces are not virtually perfect. Any flaws in these areas subjects stress directly to the rear bearing causing premature failure.

This lead to them purchasing 2 spare spindles for each machine they were running. The first thing we did when we were called in was to perform an on-site evaluation. We met with the plant manager and the maintenance department to determine the scope of the problem and the goals for the spindle repair program.
