Kyocera Corporation has introduced two new CVD coating materials, CA115P and CA125P, for turning insert grades used in automotive and industrial steel machining. The new coating technologies achieve a high level of wear and fracture resistance, resulting in a long tool life.
The newly developed CVD coating has a highly uniform alumina layer with outstanding wear resistance and a TiCN layer with excellent fracture resistance, which provide significant benefits in steel machining. Kyocera’s proprietary crystal forming technology ensures a highly uniform alumina layer during the CVD process, resulting in approximately 1.5 times higher wear resistance compared to conventional products.Â
In addition, Kyocera has introduced a PMG Chipbreaker, which covers a wide range of machining applications, in late March of this year, along with the new insert grades. The PMG Chipbreaker has a design developed using Kyocera’s proprietary expertise to achieve smooth chip evacuation in medium-roughing. The low-cutting-force design of the cutting edge suppresses crater wear on the rake face, which enables lasting chip evacuation, further contributing to longer tool life and stable machining.
