普通钢铁材料的切削加工获得了极大的发展。从硬质合金到陶瓷和立方氮化硼等刀具材料的应用已经成熟,有助于实现高效率切削。相比之下,对于不锈钢、耐热钢等难切削材料,在选用的刀具和切削规范等问题上尚不完善,这引起大家的关注。在日本,由于飞机与航天工业加工的需要,切削加工的着眼点,已从过去的钢铁材料逐步向难切削材料方面转移。本文主要以实例说明难切削材料的切削问题和应采取的措施。
The general machining of steel has gained tremendous growth. The use of tool materials from cemented carbide to ceramics and cubic boron nitride has matured to enable high-efficiency cutting. In contrast, for stainless steel, heat-resistant steel and other difficult to cut materials, the choice of tools and cutting specifications and other issues is not perfect, which aroused everyone’s attention. In Japan, due to the needs of the aircraft and aerospace industries, the focus of cutting has shifted from past steel materials to hard-to-cut materials. In this paper, an example is given to illustrate the cutting problem of difficult-to-cut materials and the measures to be taken.
