为提高螺纹磨床的磨削精度和测量效率,在1976年我们研制螺纹磨床传动链和丝杆临床动态精度测量装置时,曾对几种螺纹磨床的传动链及其所加工的丝杆精度进行了多种测量。通过这些测量,证明在机床精度及工件装夹正常的情况下,工件的周期误差主要来源于机床传动链的周期误差,而累积误差常与磨削热、机床热平衡等因素有关。因此,对螺纹磨床磨削精度的提
In order to improve the grinding precision and measuring efficiency of the thread grinding machine, in 1976, when we developed the clinical dynamic precision measuring device of the thread grinding machine drive chain and the screw thread, the accuracy of the drive chain of several thread grinders and the screw rod processed by them A variety of measurements. Through these measurements, it is proved that the cycle error of the workpiece mainly comes from the cycle error of the transmission chain of the machine when the machine precision and workpiece clamping are normal. The cumulative error is often related to the factors such as grinding heat and machine heat balance. Therefore, the thread grinder grinding precision mention
