减小车削螺距误差的几点措施鲁南机床厂侯志坚，刘凤同我们在装配调试新产品ＣＬ６１３６Ａ的过程中发现有一项工作精度处于不稳定状态：精车丝杠试件时，其螺距精度达不到ＪＢ／ＧＱ·Ｆ１００２—８６规定的合格品要求。该项精度是机床工作精度的主要项目，它的超差直接...
Several measures to reduce turning pitch error Lunan Machine Tool Plant Hou Zhi Jian, Liu Feng with our assembly and debugging of new products CL6136A process found in a work in the unstable state of precision: fine screw samples, the pitch accuracy of less than JB / GQ · F1002-86 requirements of qualified products. The accuracy is the main project precision machine tool, it’s ultra-poor direct ...
