机械加工业的展望

介绍了干切削技术在国外的发展状况，比较了干切削刀具材料的切削能力；介绍了高速切削的特点和高速切削刀具材料及目前高速切削存在的三个方面的缺陷；简介了硬加工、少无切削液（准干切削）加工技术的目前状况。

Expectation and Prospect of Mechanical Working Industry

The paper introduces the development siuation of foreign dry cutting technology and makes comparison with the cutting capacity of the cutter.The high-speed cutting is also introduced for its features and development of material .The three defects existed in the present high-speed cutting are pointed out and the present mechanical working technology situation of hard working and non- available ilquid working (quasi dry cutting)is simply introduced in the paper.
