采用硬质合金可转位机夹式刀具(以下简称机夹刀具),是我国“六五“计划期间要求重点推广的新技术之一。近年来,在一金工车间10时(即主轴直径254毫米)重型镗床、12米龙门铣床等重型铣镗床上推广的不重磨铣刀盘的应用面稳定在70%;二金工车间在中小型车床上推广的可转位车刀的应用面稳定在80%;一金工
The use of hard alloy indexable cutting tools (hereinafter referred to as machine tool) is one of the new technologies that China requires during the “6th Five Year Plan” period. In recent years, the application surface of non-refining milling cutters promoted in heavy metal milling machines such as heavy-duty boring mills and 12-meter gantry milling machines in a metalworking workshop at 10:00 (ie spindle diameter 254 mm) has been stable at 70%; The application surface of the turning tool that can be promoted on the lathe is stable at 80%;
