HSD ES915 Spindle Repair
HSD is a very popular spindle manufacturer that a lot of machine tool OEM’s use in their machines. This HSD E915 spindle is grease lubricated, stator driven, and capable of running up to 24,000 RPM.
Our customer sent in this HSD ES915 spindle stating that the spindle takes a tool but has a lot of play in it. When it arrived at Northland Tool there was quite a bit of play in the tool and the spindle was seized. Upon completing a breakdown and evaluation, we recorded that the gripper post had un-threaded and the draw bar had backed into the actuator. The rear bearings had a slight liquid contamination in them and the rear bearing journal was tapered and will need to be addressed. No other dimensional deviations were noted for this repair.
The following actions were performed on this HSD ES915 spindle:
- Clean, inspect overall dimensions
- Replace bearings, bolts, o-rings, and gripper balls
- Grind, plate, grind (GPG) the rear bearing journal
After reassembly of all components, adjusting bearing preload, and undergoing break-in and testing procedures, this spindle passed our final quality inspection before being returned to our customer with a 1-year warranty.
