虽然近年来工具材料队伍中增加了一些新品种(如陶瓷、人造金钢石),但无论从数量及应用的广泛程度来看,高速钢和硬质合金工具仍占绝对多数。这三类材料的比例为5(高速钢);4(硬质合金):1(包括陶瓷在内的其它材料)。特别对形状复杂的工具如铣刀、拉刀。剃齿刀和钻头,绝大多数是由高速钢制造的。随着机械工业及新材料 Although some new varieties (such as ceramics and artificial diamonds) have been added to the tooling materials team in recent years, high-speed steel and carbide tools still represent an absolute majority, both in terms of quantity and application. The ratio of these three materials is 5 (high speed steel); 4 (cemented carbide): 1 (including other materials, including ceramics). Especially for complex tools such as milling cutter, broach. Shaving knives and bits, the vast majority are made of high-speed steel. With the machinery industry and new materials
