Spindle Repair

6,000 RPM
This customer called us because his spindle was making too much noise even at low speeds. They were only running it at 1,000 RPM. The drawbar had already been replaced.
We picked the spindle up at the customer’s location and brought it back to our facility where we thoroughly cleaned and inspected the spindle. We determined that there was front bearing failure from the bearings reaching the end of their expected life.
The taper needed a kiss grind and the gripper fingers were worn.
We kiss ground the taper in our grinding department. We then adjusted the preload, replaced the bearings, balanced, assembled and broke in the spindle. The final step was our thorough QC check before we delivered the spindle back to the customer.
