Mitsubishi MH50D Spindle Repair
This Mitsubishi MH50D spindle is grease lubricated and gear driven, making it capable of running up to 4,000 rpm.
We received this Mitsubishi MH50D spindle in completely seized condition. Our initial inspection uncovered that the #1 front bearing had suffered catastrophic failure. Grease was largely gone from the quad set, and what was left was degraded by coolant and debris. The tooling taper ID was damaged, with poor tool contact and high runout. The 100mm front and 75mm rear bearing journals and shoulders had high runout. Gripper fingers had significant wear on tool retention surfaces.
This repair required significant grinding work to bring this spindle back to spec. We performed a grind, chrome plate, and finish grind process to the tooling taper ID, 100mm front, and 75mm rear bearing journals. A kiss grind to the bearing shoulders remedied high runout. We replaced ceramic bearings, Bellevilles, grippers, o-rings and assembly screws.
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.
