KYOCERA to Introduce New CVD-Coated Insert Grades At IMTS 2004 for Cutting Ductile Cast Iron

Mountain Home, NC – August 9, 2004 – 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.

Features of Kyocera’s CA4120 / CA4115 coating layers

TiN layer
Increases surface smoothness and anti-adhesive properties.

Al203 layer
Improves high-temperature stability and crater- and wear-resistance.

TiCN layer
Very fine columnar structure with high aspect ratio increases chip- and wear-resistance.

Provides ultra-hard structural foundation.
