铣削铸铁材料的传统切削速度为50～350m/min。由于铸铁是一种脆性材料,在铣削过程中存在着较为严重的振动和冲击,而且加工表面也存在着一定的缺陷。超高速铣削铸铁的主要目的是,在提高切削效率的同时,大幅度地提高加工表面质量。铸铁在切削加工时产生崩碎切屑。通过
The traditional cutting speed of milling cast iron material is 50 ~ 350m / min. As cast iron is a brittle material, there is a serious vibration and impact during the milling process, and there are some defects on the machined surface. The main purpose of ultra-high-speed milling of cast iron is to improve the cutting efficiency at the same time, significantly improve the quality of the machined surface. Cast iron in the cutting process produces broken chips. by
