Kyocera Corporation is introducing 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. In addition, Kyocera is launching a PMG chip breaker, which covers a range of machining applications, along with the new insert grades.

The new CA115P and CA125P insert grades – the main grades for external and internal turning for steel machining – have a newly developed coating and carbide substrate. According to Kyocera, the coating achieves the industry’s highest level of uniformity in alumina crystal orientation through the company’s proprietary crystal-forming technology during the CVD process, which helps to ensure outstanding wear resistance.

By combining this ultra-uniform alumina layer with a proprietary TiCN layer and new carbide substrate offering greater high-temperature strength, the insert grades achieve higher wear resistance and fracture resistance, as well as long tool life and stable machining. In addition, the PMG chip breaker supports various machining conditions, from medium machining to roughing, making it possible to consolidate tools and deliver productivity improvements.

CA125P grades support a wide range of machining conditions, from continuous to heavy interrupted machining, and are highly versatile main grades. CA115P grades are for high-efficiency machining in continuous to light-interrupted machining, contributing to productivity improvement through long tool life and stable machining.

Kyocera’s new PMG chip breaker achieves smooth chip evacuation in medium roughing. In addition, the low-cutting-force design of the cutting edge suppresses crater wear on the rake face, which enables lasting chip evacuation.
