涂层高速钢刀具是近年来高速钢刀具性能上的重大突破之一。1981年第4届欧洲国际机床展览会(4EMO)上已有20余家厂商首次展出了TiN涂层高速钢刀具—钻头及齿轮刀具。其中多数厂商本身没有高速钢物理气相涂层设备,而是委托专业厂代为涂覆的,以显示该刀具制造厂的生产技术水平能跟上时代。本文介绍美国各厂在工具钢和高速钢工具上进行气相沉积涂层的近况,对其应用的工艺、设备、进一步发展的打算、气相沉积涂层后高速钢刀具切削性能的改进及价格的提高等问题作了比较概括的介绍。
Coating high-speed steel cutting tools in recent years, one of the major breakthroughs in the performance of high-speed steel cutting tools. In 1981 the 4th European International Machine Tool Show (4EMO) has more than 20 manufacturers for the first time exhibited TiN coated high speed steel tools - drill bits and gear cutting tools. Most of them do not have high-speed steel PVD coating equipment, but commissioned a professional factory for coating to show that the cutting tool manufacturer’s production technology to keep up with the times. This article describes the status quo of vapor deposition coatings on tool steels and high speed steel tools in various US factories. The application of the technology, equipment, further development plan, the improvement of cutting performance and price increase of high speed steel tools after vapor deposition coating And other issues made a more general introduction.
