近来,千分表做为车间测量工具,已占有极其重要的位置。这是由于它具有比较测量器的特点;而且在大量生产中连续测量和分选都有较高的效率的缘故。但是,千分表的精度保持性仍存在着问题。日本三丰厂对此进行了改革,并试制成功。其改进方面有: 1、测杆系采用不锈钢,并经淬火后,齿条部分进行磨削加工;

Recently, dial indicator as a workshop measuring tool, has occupied a very important position. This is because it has the characteristics of a comparative measuring instrument; and it has higher efficiency in continuous measurement and sorting in mass production. However, there is still a problem with the accuracy of the dial indicator. Mitutoyo plant in Japan conducted a reform and trial success. The improvements are: 1, rod system using stainless steel, and after quenching, the rack part of the grinding process;
