对于精密机床,如何在制造水平相同的情况下,提高部件的最终装配精度或在保证部件精度要求的前提下,使零件能较经济的制造出来。本文提出几种行之有效的办法。一、定位元件付的平均效应法六十年代精密机床设计时,常按运动学设计原理,六点定位,避免静不定,减少干涉的原则进行。轴系设计中,如民德OFD广的0.2″圆刻线机,采用了顶尖和短圆柱面
For precision machine tools, how to improve the final assembly accuracy of the parts under the same manufacturing level or make the parts more economical to manufacture under the premise of ensuring the accuracy requirements of the parts. This article proposes several effective ways. First, the positioning element to pay the average effect law Sixty time precision machine design, often according to kinematics design principles, six-point positioning, to avoid static indecisive, to reduce the principle of interference. Shafting design, such as the popular German OFD 0.2 "circular engraving machine, using the top and short cylindrical surface
