新型陶瓷刀具材料是硬质合金刀具材料的发展与补充,它是在硬质合金、金属陶瓷与高温工程陶瓷的基础上发展起来的,远超出传统陶瓷的领域,从而更加提高了切削刀具的性能,并扩大了其切削加工的范围。一、陶瓷刀具材料的种类及其大致的使用范围 1.纯氧化物系陶瓷这类陶瓷多为纯氧化铝,在国外(例如西德)则有氧化铝中添加氧化锆增韧的陶瓷,主要用于切削灰 The new ceramic tool material is the development and supplement of cemented carbide tool materials, which is developed on the basis of cemented carbide, cermet and high-temperature engineering ceramics, far beyond the traditional ceramic field, so as to further improve the performance of cutting tools , And expand the scope of its cutting. First, the types of ceramic tool materials and the general scope of use 1. Pure oxide ceramics Most of these ceramics are pure alumina, in foreign countries (such as West Germany) are added zirconia toughened alumina ceramic, the main For cutting ash
