一、问题的提出在重复性批量生产中,经常为在普通镗床上镗孔,中心距超差和工效低伤脑筋。这是因为凭机床刻度控制座标精度达不到要求;采用试切法加工工效低,质量又不易保证。为此,如何提高普通镗床的座标精度就成了一些企业极待解决的课题。二、用比较法提高机床座标精度提高机床座标精度的办法很多,但在重复性批量生产中莫过于采用比较法简易可
First, the problem raised In repetitive mass production, often boring in the ordinary boring machine, the center distance and ergonomics are troubles. This is because the accuracy of coordinate control by the scale of the machine can not meet the requirements; the use of trial and cut processing efficiency is low, the quality is not easy to guarantee. For this reason, how to improve the coordinate accuracy of ordinary boring machine has become a subject to be solved by some enterprises. Second, improve the coordinate accuracy of the machine tool with a comparative method There are many ways to improve the accuracy of machine coordinates, but in the repeated mass production is more than the use of comparative method simple
