在多头螺纹车床设计中,应用“速比分头原理”(见《机床》1982年第3期),解决了自动分头方法以后,突出的是自动进刀问题。因为手动进刀,不仅要求操作者有较熟练的技术,而且要求操作者精力十分集中,这样就容易引起疲劳,从而可能产生差错,使被加工螺纹精度难以保证一致。 本文介绍 In the multi-head lathe design, the application of “speed ratio principle” (see “Machine Tool” 1982 the third period), to solve the automatic separation method, the highlight is the automatic feed problem. Because the manual feed, not only requires the operator to have more skilled techniques, but also requires the operator is very concentrated, so fatigue can easily lead to possible errors, the accuracy of the processed thread is difficult to ensure consistency.
