Kyocera Corporation has developed a new line of indexable cutting tool inserts to improve cast iron machining. Made from new grades of CVD coated-carbide materials, Kyocera’s CA3 Series and chipbreaker K Series inserts reportedly offer improvements in machining cast iron components for automobiles, industrial machinery and many other heavy-duty applications. The new inserts help make metalworking tools that can deliver stable machining performance over a wide range of cutting conditions.

The CA3 Series uses a newly developed CVD coating with a pink-gold finish over a carbide base metal. Kyocera has improved the adhesion strength of the coating layers to help ensure longer tool life and consistent processing of cast iron. It features newly designed blade-edge shapes on the new chipbreakers that can help improve performance even under high-load machining.

Three types of new materials and chipbreakers are available to address all aspects of cast iron machining, from rough cutting to finishing.

CA3 Series

Kyocera has used newly developed CVD coating technology for cast iron machining in its CA3 Series. In addition to increasing the adhesion strength of the coating layer by improving the crystalline structure of each layer, abrasion and fracture resistance have been increased by adopting hard-surface coatings and improved surface layer coating conditions, the company says. Kyocera has also adjusted the balance between layers for various applications to improve tool life and ensure consistent cutting.

K Series

The surface of a cutting tool insert incorporates grooves and uneven rough areas called ‘chipbreakers’ that break and remove chips of metal from the workpiece. A chipbreaker’s purpose is to ensure chip evacuation, thereby preventing quality problems and process interruptions caused by chip buildup and/or damaged blade edges. Kyocera’s K Series features three newly designed edge shapes to maximize performance when combined with the new materials in the CA3 Series. By creating specialized chipbreaker shapes for specific applications, higher stability and cutting consistency can be expected even under high-load cutting conditions, according to Kyocera.
