修理机床时,当着手刮平刀架、摇臂,工作台及升降台的外导轨前,必须检验它们对主要基面-轴或丝杠的平行度。 检验导轨时,由于没有什么专用的工具,所以只能利用样板和量块来检验。但这种方法需要制造大量的样板,并且导轨的找正也需要花费很多时间,尤其是仅凭自己的经验《目测》检 When repairing a machine tool, before proceeding with the scraping of the outer racks of the tool holder, rocker arm, table and lifting table, the parallelism of them to the main base surface, the shaft or the spindle, must be checked. When testing the guide rail, because there is no special tool, so can only use the model and the amount of block to test. However, this method requires a large number of prototypes to be manufactured, and the alignment of the guide rails also takes a great deal of time, especially since it is based on one’s own experience
