Mitsubishi Materials Corporation, Advanced Materials & Tools Company (President – Shinichi Nakamura, Headquarters: Otemachi, Chiyoda-ku, Tokyo) has added a new chip breaker to the MS6015 range of inserts. MS6015 is a PVD coated carbide grade for turning carbon steels.

The MS6015 PVD coated carbide grade ensures smooth surface finishes and excellent dimensional accuracy when turning carbon and free cutting steels on small automatic lathes. The combination of the special cemented carbide substrate and the PVD coating provides the ability to machine excellent surface finishes. To allow a wider range of applications, the LS-P breaker for light turning and R/L-FS breaker for precision inserts for finish cutting have been added for small parts applications.

Features of the MS6015, LS-P breaker, R/L-FS breaker

1. The accumulated Ti-CN based coating delivers excellent wear resistance at medium to low cutting speeds of 50~150 m/min that are typically used for machining small parts manufactured from carbon steel. Additionally, by optimising the accumulated coating structure, adhesion of the coating layer to the substrate is improved.

2. The new flat surface technology used in LS-P breaker for light turning, ensures a tough edge layer that vastly reduces crack development and fracturing. The LS-P breaker also provides excellent welding resistance and stable machining.

3. The R/L-FS breaker for precision finish cutting realises improved sharpness and maintains high quality surface finishes due to the narrow lead breaker.
