文本为精密螺纹磨削的研究的第五个报告,正如第二,第三,第四个报告所叙的螺距误差主要是由工件的螺纹或磨床的热变形引起,因此,本报告的目的,是在考虑到这些原因的情况下,讨论如何按照磨削条件对螺距误差进行补偿。使用数控补偿装置的结果表明,磨削1米长的丝杠,可使全长上的螺距累积误差减少到5微米左右。(这个实验是在1968年完成的)。 The text is the fifth report of a study on precision thread grinding. Just as the thread pitch errors described in the second, third, and fourth reports are mainly due to the thermal deformation of the workpiece threads or grinders, the purpose of this report, Considering these reasons, we discuss how to compensate the pitch error according to the grinding conditions. The results using the CNC compensation show that grinding a 1-meter long leadcrew can reduce the cumulative pitch error on the entire length to about 5 microns. (This experiment was completed in 1968).
