为使批量生产能长期保持高精度,就必须消除刀具刀尖磨损及机床热变形产生的误差。为了保持微米级的加工精度,常常要停机修正刀具刀尖的磨损与机床热变形产生的误差。微米级的调整,要求具有一定的经验和技术,也较耗费时间,因此操作者必须是熟练工人。在高效率、高精度批量生产的埸合,应具有简单而又迅速调整的刀具补偿装置,精度应是微米级。满足这种要求的装置有多种,它们必须具备下面条件:(A) 能进行微米级的调整,重复精度应在1微米之内;(B) 简单而又迅速地(1秒之内)进行刀具补偿,并且非熟
In order to maintain long-term high-precision mass production, it is necessary to eliminate the tool tip wear and heat generated by machine error. In order to maintain the micron-level machining accuracy, it is often necessary to shut down to correct the tool tip wear and machine tool thermal deformation error. Micron-level adjustments, require a certain amount of experience and technology, but also more time-consuming, so the operator must be a skilled worker. In high-efficiency, high-precision mass production of the joint, there should be simple and rapid adjustment of the tool compensation device, the accuracy should be micron-level. There are a number of devices that can meet this requirement, and they must have the following: (A) Micron-level adjustment is possible with repeatability within 1 micron; (B) Simple and rapid (within 1 second) Tool compensation, and not familiar
