Supfina - Fine Grinding

Fine grinding is also used when workpieces require both surfaces to have plane parallelism, but with more precision than can be achieved with double-disk grinding. Workpieces are placed in carriers that have teeth on the outside diameter. An inner pin ring rotates the carriers as they shift on a stationary outer pin ring in an orbiting manner.
