用陶瓷刀切削金属,已有多年历史。早在五十年代中期,许多工业国家已有商品供应。我国在五十年代末期也在某些加工领域中使用了陶瓷刀.但由于这种刀具性脆,使用范围极为有限。六十年代末期出现了金属陶瓷,引起了各工业发达国家很大兴趣,并在各种金属加工中推广,这在有些兄弟杂志中已有报导。本刊现摘译苏联、西德三篇有关金属陶瓷刀文章,供我国有关方面研究参考。 With ceramic knife cutting metal, has many years of history. As early as the mid-1950s, many industrialized countries already had a supply of goods.

This has been reported in some fraternal magazines. This issue shows a translation of the Soviet Union, West Germany, three articles on the ceramic knife for our country research reference.
