组合铣刀是广泛应用于加工齿轮的刀具，一般由高速钢制成。其硬度高，切削效率高，适合于大切削量的加工。在切削加工中，铁屑熔融易与刀头粘结，形成刀瘤，影响刀具的正常使用。同时，切削瞬时温度很高，刀头也易钝化，以致降低刀具的使用寿命和被加工工件的表面质量。组... Combination milling cutter is widely used in processing gear cutter, usually made of high-speed steel. Its high hardness, high cutting efficiency, suitable for processing large amount of cutting. In the cutting process, scrap iron melt easily bond with the cutter, the formation of knives, affecting the normal use of knives. At the same time, cutting instantaneous high temperature, the head is also easy to passivation, resulting in reduced tool life and the workpiece surface quality. group...
