一、概述数字控制电火花线切割机床在国内是70年初期发展起来的一种新型金属切削加工设备。目前,在模具制造过程中已是一种越来越广泛、必不可少的生产加工手段。特点是:一、对形状比较复杂的模具进行加工,精度高、质量稳定;二、可以直接对淬火钢模具进行加工,一次成形;三、简化生产工艺过程,对新产品的试制提供了方便。但 First, an overview of digital control of WEDM in China is the early 70 years developed a new type of metal cutting equipment. At present, in the mold manufacturing process is an increasingly widespread and indispensable means of production and processing. Features: First, the shape of the more complex molds for processing, high precision, quality and stability; Second, you can directly on the quenching steel mold processing, a forming; Third, to simplify the production process, the trial of new products provides a convenient. but
