Brother TC227 Spindle Repair

This customer was new to Northland Tool & Electronics. They sent in a Brother TC227 to be repaired. The HSK shaft taper had 8-10 microns runout and 16 microns runout on the face. The front bearings were worn and had very little grease in them. The drawbar grippers were also worn. We replaced the bearings. We ground, chrome plated and reground the HSK shaft taper using our Kellenberger ID/OD grinders. The spindle was then put through our standard procedure of adjusting the preload, balancing, assembling and breaking in the spindle. It was then thoroughly checked in our QC department. New customers are generally impressed with our standard one year warranty. We stand behind our work.
