有句古话“工欲善其事,必先利其器”,要是没有先进的工具,很多产品质量就提不高,甚至上不去。就这方面来说,切削工具更显得突出。近十年来,国外各先进工业国的切削刀具材料和磨具材料,以及刀具磨具结构,发展很快,以适应现代工业的需要。本文就磨具材料方面,既作了国内现有水平的介绍,也作了国外发展趋向的报导。值得注意的是,我国在一个时期内,研究发展磨料新品种的速度相当快,1973年以前,已定型的品种有13种,但到目前为止能正常供应的只有5种,严重影响了新工艺、新材料、新产品的应用和发展,也阻碍了我国机械工业水平的提高。推其原因可能是多方面的,希望能引起有关领导部门的重视,迅速研究,采取有力措施,把磨料磨具的品种搞上去。我们深信,从事机械行业的同志们,对这类共性的问题,一定也很关心。今后我们打算请作者再在磨具方面,另行撰文,以饷读者。
There is an old saying, “Workers want good things, must first sharpen their tools,” if there is no advanced tools, many product quality is not high, not even go up. In this regard, cutting tools are even more prominent. In the past decade, the cutting tool materials and abrasive materials and the structure of tool and abrasive tools in various advanced industrial countries abroad have developed rapidly to meet the needs of the modern industry. This article on the abrasive materials, both as a domestic present level of introduction, but also made a report of the trend of development abroad. It is noteworthy that our country in a period of research and development of new varieties of abrasive very fast, before 1973, there are 13 kinds of stereotypes, but so far only 5 kinds of normal supply, seriously affecting the new technology , The application and development of new materials and new products also hindered the improvement of China’s machinery industry. The reason may be pushed in many ways, hoping to arouse the attention of the relevant leaders, promptly study and take effective measures to make the varieties of abrasive abrasives up. We are convinced that comrades engaged in the machinery industry must also be very concerned about such common problems. In the future we intend to ask the author and then in the abrasive, separate author, to readers.
