Race grinding

The race grinding process is mainly used in the bearing industry and is primarily a subdivision of external cylindrical grinding (inner ring) and internal cylindrical grinding (outer ring).

The necessary removal rate is achieved in a straight or angular plunge grinding process

The necessary removal rate (~ 0.3 mm from the diameter) is achieved in a straight or angular plunge grinding process depending on the type of ring.

As the races are finished with honing stones after the grinding process, the surface finish to be produced in the race grinding process should be between 0.3 and 0.5 µm Ra max.

Depending on the generation of machines used, the vitrified bonded aluminium oxide grinding wheels operate with increased circumferential speeds of up to 125 m/s.
