超高速切削技术是目前各工业发达国家努力发展的一项高新技术,在美国、德国等国家已开始生产商品化的超高速切削机床。本文介绍切削钢铁的超高速铣削技术,分析切削过程中切屑变形、切削力和温度、刀具磨损、表面质量等方面不同于传统速度铣削的特点。 Ultra-high-speed cutting technology is currently a high-tech developed by all industrialized countries. In the United States, Germany and other countries, it has started to manufacture commercialized ultra-high speed cutting machine tools. This paper introduces the ultra-high-speed milling technology of cutting steel, analyzes the characteristics of chip deformation, cutting force and temperature, tool wear, surface quality and other aspects different from the traditional speed milling during cutting.
