Outer bearing ring

This outer bearing ring was machined on the Mikroturn 100 in two clamping set-ups, in order to machine the OD and ID. The goal was to elimimate a multi step grinding process, ID and OD grinding. Hembrug can succesfully replace the grinding process with hard turning, while keeping the required accuracies.
