Hardinge HMC Spindle Repair Case Study

Upon breakdown and inspection of the spindle, we found that there was no sealant on the rear flange, which may have led to premature rear bearing contamination. There was excessive wear on the Big Plus 50 ID taper that required grind-plate-grind. Our Technicians also rebuilt the drawbar of this spindle to have the pull force needed to hold the tool securely in the shaft. A new pair of angular contact bearings and roller bearings were replaced in the spindle, when it was rebuilt by one of our many experienced Spindle Technicians. Once assembled, the spindle was balanced and test run for four(4) hours. Our Technicians were able to balance and fine tune this spindle to such an exacting degree, that the spindle runs as if it were new.
