万能分度头是用得很广泛的分度工具,但在有些情况下,原来的一些分度方法不够用。本文介绍几种经过实践的分度方法,仅供读者参考。一、补差分度法当工件等分为较大的质数(如:61、67、71……107)时,可以采用此法。这种分度方法的特点,是根据工件精度不同,在近似分度过程中,分段地弥补各分度阶段中所产生的累积误差,以提高分度的精度。应用补差分度时,需事先在分度盘的边缘刻度,每格为40分(见图1),这样,主轴相应是1分。
Universal indexing head is a very widely used indexing tool, but in some cases, some of the original indexing method is not enough. This article describes several practices after the indexing method, for reference readers. First, make up difference method When the workpiece is divided into larger primes (such as: 61,67,71 ...... 107), you can use this method. The characteristic of this indexing method is that according to the difference of workpiece accuracy, in the process of approximate indexing, the accumulated errors generated in each indexing stage are made up in stages so as to improve the accuracy of indexing. The application of sub-degree of differentiation, the need to dial in advance of the edge of the scale, each grid is 40 points (see Figure 1), so that the corresponding spindle is 1 minute.
