PCBN tool is an artificial cubic boron nitride tool, in high temperature can also maintain high hardness characteristics, mainly for the processing of iron.CBN(Cubic Boron Nitride) was first synthesized by us general electric (GE) under high temperature and high pressure by the manual method in the 1950s. Its hardness is second only to diamond but far higher than other materials, so it is collectively referred to as superhard materials with diamond.
PCBN 커터의 특징
첨가 성분에 따라 PCBN은 CBN 단결정 직접 소결법과 일정 비율 접착제 소결 PCBN 두 가지로 나뉜다.복합재료의 준비방법에 따른 PCBN 소결블록은 토탈 PCBN 소결블록과 경질합금 복합소결 PCBN 복합시트로 구분된다. 점결제를 포함하는 PCBN 복합시트가 광범위하게 적용되고 있다.PCBN의 경도는 접착제 첨가 비율에 따라 다릅니다.점착제 함량이 높을수록 경도가 낮을수록 인성이 좋다.다른 종류의 접착제, PCBN의 사용은 다르다.
CBN is widely used in grinding because of its high hardness, chemical inertia and thermal stability under high temperature. Because the CBN has better than the other characteristics of the cutting tool material, so people began trying to apply to machine, but smaller particles of monocrystalline CBN, it is difficult to make knives, and CBN sintering property is very poor, difficult to make a larger CBN sintered body, until the 1970 s, the former soviet union, China, United States, Britain, and other countries have been developed as a cutting tool of CBN sintered body, Polycrystalline Cubic Boron Nitride PCBN (Polycrystalline Cubic Boron Nitride). Since then, PCBN has been applied in various fields of cutting with its superior cutting performance, especially in the cutting of high hardness materials and difficult materials. After more than 30 years of development and application, PCBN tool materials for processing different materials have emerged.
