一、前言 M_2Al高速钢是在文化大革命中,广大工人和革命技术人员,狠批爬行主义、洋权哲学,坚持毛主席独立自主、自力更生的方针结合我国资源状况,研制出的一种无钴超硬型高速钢。经过几年的生产、试用,给果表明这种高速钢具有优异的综合性能(比普通高速钢刀具提高效率二至十倍),深受切削加工部门的欢迎,但其可磨加工性能较普通高速钢差,为此一机部把此种新型高速钢的磨削工艺列为重点研究项目。1975年12月一机部在广东省韶关
I. Introduction M_2Al high-speed steel is in the Cultural Revolution, the majority of workers and technicians, severely criticized reptileism, foreign-rights philosophy, adhere to the principle of independence and self-reliance Chairman Mao combined with the situation of our resources, developed a cobalt-free super-hard High-speed steel. After several years of production, trial, the fruit shows that this high-speed steel with excellent overall performance (compared to ordinary high-speed steel cutting tools to improve efficiency of two to ten times), welcomed by the cutting department, but its grinding processability than the ordinary High-speed steel is poor, for which a machine to the new high-speed steel grinding process as a key research project. 1975 December a unit in Shaoguan, Guangdong Province
