Bridgeport Torq-Cut Spindle Repair
The Bridgeport Torq-Cut is a CNC vertical machining center. It comes fitted with a grease lubricated and belt driven spindle capable of running up to 6,000 rpm.
Our Customer sent in this Bridgeport Torq-Cut spindle stating it was noisy when running cold. Once it arrived at Northland Tool and Electronics we completed a full breakdown and evaluation. Upon assessment, we noted that the bearings were starting to fail from use and the grease was turning yellow. The taper showed signs of wear from use and had pock marks. The taper gauge line and contact were measured within specification, but the taper will need a cosmetic kiss grind. Lastly, the belleville grease was caking. No dimensional deviations were noted for this repair.
The following actions were performed on this Bridgeport Torq-Cut spindle:
- Clean, inspect overall dimensions
- Replace bearings, bellevilles, crush rings, o-rings, gripper balls, and assembly screws
- Kiss grind the tooling taper
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.
