随着四化建设的需要,工业生产也日益发展。为了提高产品质量,发展新品生产,对模具的数量和质量就成为各厂目前迫切需要解决的问题了。我国的数控线切割机床虽然很多,但要在原有设备中,不加任何改进,工艺上不采取任何措施就加工出几何精度在 With the need of the four modernizations, industrial production is also growing day by day. In order to improve product quality and develop new products, the quantity and quality of molds have become urgent problems to be solved by various factories. Although China’s CNC wire-cutting machine tools, although a lot, but in the original equipment, without any improvement, the process does not take any measures to produce a geometric accuracy of
