中伏尔加机床制造厂车工科列索夫由于在车削钢制件时应用了加大进刀量的方法,便给提高劳动生产率的工作带来了重大的贡献。科列索夫的方法规定使用革新者自己研究出来的、具有新几何形状的车刀。这种车刀有三个切削刃:45°角的主切削刃,平行于所加工零件表面的副切削刃,和连接这两个切削刃成20°角的过渡刃。当进刀量等于1至3公厘/转的时候,使用宽切削刃的零件加工法的本质是:在主轴转数比较小的情形F,能够缩短机械时间若干倍(二至十倍),同时还能大大地节省电能和提高所加工的表面的光潔度。
The workers at the Volga Machine Tool Works Kozlovskof made a significant contribution to the improvement of labor productivity by applying the method of increasing the amount of feed when turning steel parts. Kozlitov’s approach stipulates the use of turning tools of a new geometry developed by the innovators themselves. The turning tool has three cutting edges: a 45 ° main cutting edge, a minor cutting edge parallel to the machined part surface and a transition edge at an angle of 20 ° connecting the two cutting edges. When the amount of feed is equal to 1 to 3 mm / rev, the nature of the part machining method using a wide cutting edge is that in the case of a small spindle revolution F, it is possible to shorten the mechanical time by several times (two to ten times) At the same time, it can also save energy and increase the finish of the machined surface.
