Kyocera Introduce 2 New CVD Coated Grades for Cutting Ductile Steel

Kyocera’s CERATIP Cutting Tool Division will introduce two new CVD-coated grades for cutting ductile cast iron, CA4120 and CA4115, at the 2004 International Manufacturing Technology Show (IMTS 2004), Sept. 8-15 at Chicago’s McCormick Place.

Ductile cast iron is a high-strength metal that comes in many complex shapes and is difficult to cut. Kyocera’s CA4120 and CA4115 grades feature a newly developed CVD coating with a very fine columnar structure specifically designed to address the challenges of cutting ductile cast iron. The new coating makes CA4120 and CA4115 cutting tool inserts more crack-resistant, wear-resistant, and chip-resistant. As a result, these new products offer tool life double that of conventional tools, enabling the stable processing of ductile cast iron where both continuous cutting and interrupted cutting processes are involved.

CA4120, which offers outstanding chip-resistance, is suitable for interrupted cutting of gray cast iron or the high-strength ductile cast-iron; CA4115, which offers superior wear-resistance, is designed for continuous cutting of high-strength ductile cast iron.


Five chipbreaker geometries are available for a wide variety of cutting applications.
