随着国家各类技术标准建立,英制标准的产品均被逐步淘汰。然而有些企业的英制车床性能尚好,不到报废的程度,究竟怎样使用这批设备,就成了我们必须考虑的问题。大家知道,用英制车床加工公制螺纹,只能用正反车的办法车削,而反车速度慢,退刀占去大量工时,一般生产效率很低。要想很好发挥英制车床的作用,只有对其进行 With the establishment of various national technical standards, British standard products have been phased out. However, some enterprises of the British lathe performance is good, less than the extent of scrap, how exactly the use of these devices, it has become a problem we must consider. As we all know, metric inch thread lathe machining, can only use the method of turning the car, and anti-car speed, take-off accounted for a large number of working hours, the general production efficiency is very low. To make good use of the role of the British lathe, only to its
