Thread: CNC spindle repair

Depends on the type of spindle? Some cartridge spindles req a high pressure hydraulic system to expand the retaining nuts. If the spindle just has bad bearings and the inner races have not spun on the main shaft then you probally you can rebiuld it yourself. You need to have bearing knowledge(adjusting the pre-load ect.. and equipment) Bearing warmer. Can be done with hammers but I am a prof and dont use them personely. Mark everthing!!!...

Google a company called PBA, Precision Balancing and Analyzing They were the competition at my last day job. Not cheap though.

I have a old "OYAA" milling center with bad spidle bearings. I have never attempted this big of a repair before and would like to know if this is a "over my head repair". If any one knows any repair service in the Norfolk, Va area that would do a repair like this, Please let me know. THANKS Mike C
