Holders For Ceramic Insert
Material Introduction
[Ti (CN)], a new type of titanium nitride ceramic gives mixed ceramic grade better wear resistance and edge cutting stability for turning and milling applications. The improved hardness makes the ceramic material ideal for hard turning of hardened steel, steel rolls and finish turning of cast iron.
Ceramic insert for hard turning is capable of running at high speed, high temperature, and hence saving production time. For example, CNMG-Ceramic insert is designed for better oxidation resistance, and maintain excellent hardness even in highly increasing temperature.
Features Of Ceramic Inserts
Superior heat resistance of ceramic inserts enables high speed machining and good surface finish quality due to low affinity to the work piece; Ceramic inserts show good wear resistance and life performance when it comes to hardened steel, and cast iron.
The tool holding system is same as CBN using standard holders and spare parts. We also have various tool holder for selection. CNC machines tools in customer's factory can be used as standard.
