Precision Shafts for Motors and Drives
Motor shafts need accurate bearing journals, good straightness and clean keyways. We turn shafts on CNC lathes, mill flats and keyways, and finish critical diameters by cylindrical grinding.
- Bearing journals finished by grinding
- Keyways, flats, D-cuts and threads
- Heat treatment and surface finishing on request
