| description | The present invention relates to a PVD thin film coating cutting insert which can be suitably used for processing difficult-to-cut materials with low thermal conductivity such as Inconel or titanium. The cutting insert according to the present invention includes: a cemented carbide base material having an SMS value of 50 to 80 obtained by Equation 1, SMS = saturation magnetization value of a sintered body x 100 / TMS (TMS = 2010 x mass ratio of Co); and a ceramic thin film having a thickness of 0.4 to 1.5 μm formed on the cemented carbide base material.
본 발명은 인코넬이나 티타늄과 같이 열전도도가 낮은 난삭재의 가공에 적합하게 사용될 수 있는 PVD 박막 코팅 절삭 인써트에 관한 것이다. 본 발명에 따른 절삭 인써트는, 하기 [식 1]에 의해 구해지는 SMS 값이 50 ~ 80인 초경합금 모재와, 상기 초경합금 모재 상에 형성된 두께 0.4 ~ 1.5㎛의 세라믹 박막을 포함하는 것을 특징으로 한다. [식 1] SMS = 소결체의 포화자화값×100/TMS (TMS = 2010×Co의 질량비) |
