中国有句老話:“工欲善其事,必先利其器”。可知,不断提高机械加工的質量和效率,在相当程度上与切削工具的完善与否有关。随着机械工业的迅速发展,近几年来世界各国对刀具作了很大的改进,并取得了相当成績。現仅就我們所見所聞,归納为以下几点加以概述。1.刀具結构的改进; 2.确定刀具切削部分的合理几何参数; 3.增加刀刃有效部分的长度; 4.增大容屑空间; 5.采用合理的断屑(分屑)方式; 6.发展装配式刀具結构; 7.采用新型牌号的工具材料。
There is an old saying in China: “For workers to do their best, they must first make profits.” We can see that continuously improve the quality and efficiency of machining, to a certain extent, with the improvement of cutting tools or not. With the rapid development of the machinery industry, the countries in the world have made great improvements in the tooling in recent years and have achieved considerable success. Now just what we saw and heard, summarized as follows to outline. 1. Improve the structure of the cutter 2. Determine the reasonable geometric parameters of the cutting part of the cutter 3. Increase the length of the effective part of the cutter 4. Increase the volume of the chip carrier 5. Use reasonable chip breaking method Development of assembly tool structure; 7. The use of new grades of tool material.
