自七十年代初期,人们将真空低温等离子体涂覆技术应用到高速钢刀具上以来,获得了令人十分震惊的效果。到目前为止,在一些工业发达的国家中,涂层高速钢刀具的覆盖率已到30％左右,在可转位刀具中已达50％左右,在齿轮加工中达到50％～70％。用于涂层处理的刀具种类有齿轮滚刀、插齿刀、花键铣刀、端铣刀及其它铣刀。此外,还有丝锥、钻头、拉刀、可 Since the early 1970s, people have been shocked by the fact that vacuum cryogenic plasma coating technology has been applied to high-speed steel tools. So far, in some industrialized countries, the coated HSS tool coverage has reached about 30%, about 50% in indexable tools and 50% -70% in gear processing. The types of tools used for coating are gear hobs, chain cutters, spline mills, end mills and other milling cutters. In addition, there are tap, drill, broach, can
