ON THE CHARACTERISTICS OF HIGH-PERFORMANCE INTERNAL PEEL GRINDING USING ELECTROPLATED CBN WHEELS

The enhancement of material removal rates in hard machining is one major aspect of the applied cutting technologies; to increase the production rates. With respect to the required part quality, emphasis is put on the finishing process as a key element of the process chain. Especially internal finish operations constitute a challenging task because of the complex contact situation. This article presents a recent study on internal peel grinding, using the combined roughing-finishing procedure in combination with the excellent cutting performance of electroplated CBN wheels, to achieve highest removal rates with high surface finish.
