PMK Face Milling System

CeramTec’s PMK face milling cutter system is ideally suited for rough milling and finishing of gray cast iron and ductile cast iron materials. These milling cutters work with an approach angle of 88°. In order to attain outstanding surface qualities during finishing, the PMK series has been fitted with insert seatings that can be set in the Z-direction. When the specially-developed broad finishing inserts are preset in the μm range they can generate surface roughness values of up to 0.5 μm. The SPK® inserts in their fixed seatings take care of the cutting work; the finishing inserts create the surface with their preset, slightly higher position. For HPC rough machining operations using the PMK milling cutter system, the adjustable insert seatings are equipped with roughing inserts and set to the same height as the inserts in the fixed insert seatings.
