Mori Seiki SH40

The taper of this spindle had build up causing tool run out. The front bearings were contaminated and the front housing was over sized. All these factors contributed to bad part finish that eventually lead to our customer to send the spindle to Northland Tool for repair.

We ground plate ground the front housing and the 40 taper in our grinding department. The spindle was then assemble in our clean room. The final quality test showed less than 2 microns repeatable run out on a 12 inch test bar over multiple tool changes. This was exactly what our customer needed for his process.
