CA4505 and CA4515 Inserts

June 01, 2010

Kyocera Industrial Ceramics Corp., Cutting Tool Div. announced its new CA4505 and CA4515 CVD-coated carbide grades of indexable cutting tool inserts for machining gray and nodular (ductile) cast iron. Featuring Kyocera's new Bright Black (BB) coating, the CA45-series resists premature insert wear and fractures, according to the company. There are several key advantages of the Bright Black CVD-coated CA45-series, including: Improved CVD coating adhesion provides enhanced anti-peeling performance through optimal layer composition consisting of an ultra-fine TiCN layer, an alpha-alumina layer and Kyocera's special-surface top layer. The special-surface top layer treatment reduces material build-up on the insert cutting edge and improves surface finishes on the workpiece, while reducing insert chipping during the machining process. The two new grades cover a variety of applications pertaining to the machining of gray and nodular cast iron: CA4505 reportedly offers excellent wear resistance for continuous machining, and CA4515 is for continuous or interrupted general-purpose machining.
