采用球杆仪与激光干涉仪相结合的方法,对BV75立式加工中心进行精度检测与误差补偿,找出了影响机床加工精度的主要原因。对机床所存在误差进行了补偿,提高了机床的定位和重复定位精度,满足了加工的需要,为从事提高和恢复机床精度的操作人员提供了一套可借鉴的操作方法。 By using the combination of ballbar and laser interferometer, the precision testing and error compensation of BV75 vertical machining center were carried out to find out the main reasons that affect the machining accuracy. The error existed in the machine has been compensated to improve the machine positioning and repeat positioning accuracy to meet the needs of processing, in order to improve and restore the accuracy of the machine operator provides a set of reference methods of operation.
