序言目前日本的切削刀具仍以硬质合金、高速钢刀具为主,其中尤以硬质合金的用量最大。但是,由于硬质合金的主要原料钨矿石价格上涨,以致生产成本不断增加,货源也成问题。为了摆脱这种状况和利用高速切削以降低生产成本,陶瓷材料便引起了人们高度的重视,本文简介了陶瓷刀具的制造方法,性能和特点,展望了此种材料的发展前景。 Preface At present, Japan’s cutting tools are still cemented carbide, high-speed steel cutting tools, especially the largest amount of carbide. However, as tungsten carbide, the main raw material for cemented carbide, has risen in price, the cost of production has been on the rise, and the supply has become a problem. In order to get out of this situation and use high-speed cutting to reduce production costs, ceramic materials have attracted people’s attention. This paper describes the manufacturing methods, performance and features of ceramic tools, and prospects for the development of such materials.
