读了贵刊今年第1期刊登的“对角度块传递系统的讨论”一栏中的几篇文章,我们基本同意文章中的观点。我厂是角度块的生产单位之一。我们生产的角度块工作角的公称值均按工具专业标准GL4—62的规定。其组合有94块组和36块组两种。多年来,我们深感由于角度块组合中块数过多,而一组中经常使用的仅有十余块,这就造成浪费。另外在角度块的制造工艺过程中,决定其精度的主要工序——研磨,是手工操作,生产效率低。同时由于角度块外形为不等截面,且其测量面的平面性和光洁度要求均很高,因此操作技术很难掌握,特别是工作角公
After reading a few articles in the column of “Discussion on the Angle Block Transfer System” published in the first issue of this year, we basically agree with the views in the article. Our factory is one of the production units of angle block. We produce the angle block work angle nominal value according to tool professional standards GL4-62 regulations. The combination of 94 and 36 groups of two groups. Over the years, we feel deeply overwhelmed by the fact that there are too many blocks in a block of angles and only a few dozen of them are often used in a group. This is wasteful. In addition, during the process of manufacturing the angle block, the main process of determining its precision - grinding, manual operation and low production efficiency. At the same time as the angle of the block shape for the unequal cross section, and the measuring surface of the flatness and finish requirements are high, so difficult to master the operating techniques, especially working angle
