Spindle Repairs

Reconditioning of a spindle beings with a visual inspection and total indication run-out. Then we disassemble it, inspect and Magnaflux for cracks all internal parts including the bearings, bearing surfaces, taper, Bellville, washers, seals and seal areas. We grind the bearing surfaces and taper and apply hard chrome to these areas. Then these areas are finish ground to original specifications. Chrome is a harder substance than is usually used in machine steel (72 Rockwell on a C scale as opposed to approximately 48-50 Rockwell) giving you a longer lasting bearing and machine surface and thereby reducing wear. This will also extend the life of your live tooling. Then the spindle is reassembled with new bearing and Bellville washers, replacing any other worn internal parts as necessary, and the unit is tested.
