At High Speed Technologies, Inc. we repair Mazak VTC Spindles to original factory condition. Our repairs come with a one year warranty. This Mazak spindle was sent to us because of vibration and poor part finish. After our comprehensive repair the spindle performed like new.

Our inspection revealed 8 micron run out at the taper and a failed rear bearing.

It was evident that the taper ID was damaged and needed our GPG process. So that was started right away. All of the bearings were replaced with top name brand Super Precision spindle bearings.
