PCBN tool has high hardness and wears resistance, can in high cutting speed for a long time to produce high-precision parts (small size dispersion), greatly reduce the number of tool changes and tool wear compensation downtime time. Therefore, it is very suitable for tools and a higher degree of automation processing equipment and can make efficient equipment can be given full play.
In the application of difficult machining materials, the PCBN tool has also shown its excellent performance. Such as surface spray welding (coating) material processing, processing with other materials, tool life is very low, can not be processed by grinding method, and PCBN is the only suitable tool material. For example, the use of high alloy wear-resistant cast iron in petroleum power station equipment, the use of PCBN tool than carbide tool to improve the cutting efficiency of more than 4 times, the cost of a tool down to the original 1/5. In addition, in the cutting of sintered materials such as carbide, the PCBN tool also shows good cutting performance.
PCBN은 높은 경도와 내마모성으로 화학적 불활성의 고온에서 철족 금속과 반응하지 않기 때문에 고경도 소재와 난가공 재료의 가공에 주로 사용된다.고속강, 조질강, 고온합금, 고합금 내마모성 주철, 소결금속재, 표면분사용 용접재와 같은 난가공재.
1. Machining hardened steel can play the effect of replacing grinding with a car, because the cutting depth is more than ten times greater than the grinding depth, so the processing efficiency is high, the surface does not produce burns. For example, when the variable speed sliding gear (20CrMnTi, HRC58 ~ 62 hardness) is machined by the car instead of grinding, the cutting efficiency is increased by more than 4 times compared with the original grinding. 2. Processing of high alloy (containing tungsten or chromium 18%) wear-resistant cast iron. Cutting speed than the carbide tool increased by more than 10 times, cutting efficiency increased by more than 4 times. 3. 높은 코발트 크롬몰륨은 부식 저항성이 강하다.PCBN은 160m/min의 가공속도로 경질합금 커터의 8배에 달한다. 4. Processing of thermal spraying (spray welding) materials, surface spray welding parts can not be processed by grinding, and the cutting efficiency of the carbide tool is very low. After the use of the can improve the processing efficiency, save more than 50% of the processing cost. PCBN tool can also be used for non-ferrous metal precision cutting and sintering metal cutting and so on. 베이징 데미나의 금강석공구 연삭기는 분쇄도가 높은 CBN 공구를 연마할 수 있다.
