精密丝杠是螺纹磨床最关键的零件。我厂自行设计制造螺纹磨床以来,先后磨出螺纹长535毫米(工件长902毫米)及螺纹长960毫米(工件长1436毫米)的“0”级丝杠(新标准5级)。但对于螺纹长度大于1.5米丝杠加工,较长时间来加工精度仃留在“1”级(新标准6级),74年在加工工件长2100毫米,螺纹部长度1700毫米的高精度丝杠时,由于存在着技术方面的一些问题,丝杠的磨削精度最后只能达到或接近“1”级精度,通过研磨修整后,才能
Precision screw thread grinder is the most critical parts. Since our factory designed and manufactured the thread grinder, we have successively grind the “0” grade screw (new standard grade 5) with 535 millimeters length (902 millimeters long) and 960 millimeters long (1436 millimeters long). But for the screw length greater than 1.5 m screw machining, machining accuracy for a long time to stay in the “1” level (the new standard 6), 74 in the processing of the workpiece length of 2100 mm, 1700 mm thread length of the high-precision screw , Due to the technical aspects of the existence of some problems, the final screw grinding precision can only reach or approach the “1” level of precision, through the grinding trimming after
