KYOCERA Releases CA410K/CA415K CVD Cast Iron Grades

KYOCERA is excited to announce the release of the new CA410K/CA415K CVD coated carbide grades, a next-generation solution for cast iron machining. Combining advanced coating layers, a robust carbide substrate, and an extensive range of chipbreakers, these grades deliver exceptional wear resistance, fracture resistance, and long-term stability for a wide range of applications.

Engineered for optimal performance, the CA410K grade is optimized for continuous machining operations, providing exceptional wear resistance at elevated cutting speeds. In contrast, the CA415K is tailored for interrupted to heavy-interrupted machining, ensuring maximum cutting stability under demanding conditions.

These grades incorporate KYOCERA’s proprietary coating technology, which balances durability and performance. This newly developed coating technology features optimized rake and flank face properties to balance wear and fracture resistance. A distinctive black and gold finish is more than cosmetic: its black rake face includes a thick, highly uniform alumina layer to reduce wear, suppress delamination, and minimize fracturing, while the gold flank face incorporates a hard surface layer, alumina layer, and TiCN layer to enhance wear resistance and make used edges easy to identify. Underneath, a tough carbide substrate improves adhesion, suppresses delamination, and resists cracking for long tool life even in harsh cast iron cutting environments.

A key advantage of the CA410K/CA415K series is its wide selection of chipbreaker designs, from finishing to roughing, ensuring optimal cutting performance across multiple cast iron applications. New mesh processing technology further enhances coating adhesion and chipping resistance, extending tool life under both high-speed and interrupted conditions.
