Product Introduction

The main preparation method of cubic boron nitride polycrystalline sintered body is sintered with cubic boron nitride powder and a small amount of binder (such as cobalt, aluminum, titanium and titanium nitride) under the pressure of 4000 ~ 8000 MPa and the temperature of 1300 ~ 1900 ℃; Polycrystalline sintered body with cemented carbide substrate is prepared by sintering cubic boron nitride powder and binder as a layer and cemented carbide (sheet or powder) as a layer under the above pressure and temperature; hence the wear resistance, anti-chemical reaction, and quality reliability is better.

SNGN CBN insert is a popular size in hardened steel, stainless steel and other materials with higher hardness. As a PCBN turning insert supplier, we are able to select different edge preparation for customer's application for better efficiency and improved life. All geometries in F, S, T are available. We provides various CBN full form insert, cutting insert, turning and milling cbn insert in various material applications, for example cbn insert for stainless steel, hardened steel, carbide roll etc.

Product Properties

1. PCBN cutting inserts are sintered at high temperatures and pressure with six-face presser, thus demonstrate extremely strong abrasion resistance, heat resistance and chemical　stability.

2. Surface finish can be achieved Ra0.8, turning instead of grinding,
