CBN insert for engine cylinder block and cover turning

CBN (Cubic boron Nitrid) own the up to 4500HV hardness characteristics, which is very close to the hardness of synthetic diamond; at high temperature, PCBN also own high thermal conductivity and high chemical stability. The above advantages make processing quenching hardware at high cutting parameters possible. In addition, excellent abrasion resistance of PCBN significantly extends tool life, which can meet the strict  requirements dimensional tolerances, as well as maintain excellent surface quality.

All PCBN inserts produced by Henan More Superhard tools Co., Ltd apply the peripheral grinding with very high accuracy.

One of important advantages of PCBN inserts is that it can replace less efficient and more expensive quenching hardware grinding. Compared to grinding, the application of PCBN inserts for turning can significantly reduce the single piece cost.

Slogan: turning instead of grinding

 We are devoted to the high speed dry turning with out fluid.

CBN super hard materials processing application:

The solid CBN inserts can be used to process above RH50 degrees quenching hardware and casting such as high-manganese steel, tool steel, bearing steel, high-chromium alloy, gray cast iron, HT250

Work pieces: high speed steel rolls, metallurgical rollers, wind power generating gears, bearings, slewing bearing, quenching bearing rings, ball screws, automotive brakes disc,  engine cylinder block and liner, slurry pump parts processing, mining machinery parts and components processing.

Features：
