三三一厂在使用机夹端面铣刀过程中,因没有高精度的专用周边磨床,刀片精化原是用万能方法刃磨的。而刀片要求转位精度高,C级刀片的精度为 d~(+0.025)、m~(+0.012)、s~(+0.025),刃磨工时高达72分钟/片,质量也难以保证。后来,刀具试验室工人陈胜华同志参照国内外周边刃磨机床的结构,设计出了能在普通 March 31 plant in the use of folder end milling process, because there is no special high-precision peripheral grinder, blade refining is the original use of a versatile sharpening method. The blade requires high index accuracy. The accuracy of C-class inserts is d ~ (+0.025), m ~ (+0.012), s ~ (+0.025), sharpening working time is up to 72 minutes / piece, the quality is difficult to guarantee. Later, the tool lab worker Chen Shenghua reference domestic and foreign organizations around the grinding machine, designed to be in the ordinary
