工具车间在车制各种梢子、螺钉及各种带有圆势的机件时,都是用高速钢磨成的刀具。由于种类多数量少,型式不一,每个车工必须备有大量的刀具。因为这种刀具使用率很低,制造也很费事,所以很不经济。车工徐茂康同志,利用废的割刀片头子做刀具,并改了一把专用刀排。图中1是挡块;2是楔形压板,其中一个端面要磨成圆势作为卷屑槽,用高速钢制成;3是割刀片头子:4是刀体。车制小件的切削速度通常不会太高,所以用较薄的刀片是没有什么影响的,经车间试用后觉得有下列
Tool workshop in the car all kinds of shoots, screws and all kinds of mechanical parts with a circular potential, are high-speed steel mill into the tool. Due to the small number of species, different types, each turner must have a large number of tools. Because this tool is very low usage, manufacturing is also very troublesome, so it is not economical. Machinist Xu Maokang comrades, the use of waste cutting blade leader do knives, and changed a special knife row. 1 is a stopper block; 2 is a wedge plate, one of the end surface to be ground into a circular volume as a chip flute, made of high-speed steel; 3 is cutting blade head: 4 is a knife body. Small pieces of car cutting speed is usually not too high, so with a thin blade is no effect, after the workshop trial feel that the following
