在机器制造工业中,制造金属切削刀具需要大量高速鋼。但在我国目前情况下,高速鋼供应是很困难的;同时高速鋼也很昂贵。因此。寻求节约高速鋼的刀具制造工艺,以降低刀具制造成本,解决高速鋼供应不足的困难,是当前重要的工作。制造整体高速鋼刀具是不经济的,因为制造形状复杂的刀具,成品刀具只占刀具毛坯的40～60％,其余金属都变成了鋼屑;同时,刀具工作部分是刃口,而其他部分是不需要很高硬度和很好的耐磨性及耐热性,但是
In the machine building industry, a large amount of high speed steel is required to make metal cutting tools. However, in the current situation in our country, high-speed steel supply is very difficult; at the same time, high-speed steel is also very expensive. therefore. Seeking to save high-speed steel tool manufacturing process, in order to reduce tool manufacturing costs, to solve the problem of insufficient supply of high-speed steel, is currently an important task. It is uneconomical to make the whole high-speed steel cutting tool. Because the finished cutting tool only accounts for 40-60% of the tool blank, the rest of the metal becomes the steel scrap. Meanwhile, the working part of the cutter is the cutting edge, while the other parts It does not require high hardness and good wear resistance and heat resistance, however
