Ceramic Inserts
Overview
Ceramic Inserts for Hard Turning, Turning in Cast Iron Materials, and Turning in High-Temp Alloys
• Ceramics offer greater wear resistance and toughness.
• Ceramics can be used in high-speed, continuous, and lightly interrupted turning
applications in cast iron materials.
• Ceramics can be used for high-speed applications in high-temp alloys.
