为了提高丝杠磨床加工精度,过去在机床上传统地采用了机械校正装置,它虽然较有效地消除了机床母丝杠的累积误差,但对消除丝杠的周期误差却显得无能为力。为了解决这个问题,我们在激光丝杠动态测量仪研究成果的基础上,经过反复试验,终于在SG7430丝杠磨床上研制成功了激光自动校 In order to improve the machining accuracy of the screw grinder, the mechanical correction device was traditionally adopted on the machine tool. Although it effectively eliminated the accumulated error of the machine screw, it failed to eliminate the periodic error of the screw. In order to solve this problem, on the basis of the research results of the laser lead screw dynamic measuring instrument, after repeated tests, we finally succeeded in developing a laser automatic school on SG7430 screw grinder
