随着我国机械工业的飞速发展,各种新工艺不断踊现。电火花加工是其中发展最快的一个项目,它的应用日益广泛,特别是在各类模具的制造方面,越来越显示出它的优越性。和机械加工的情况一样,表面光洁度也是电火花加工的一项重要指标。我们知道,电火花加工的表面和机械切削加工的表面不同,它是由无数小坑和光滑的小硬突起所组成,特别利于保存润滑油,在相同的粗糙程度下其减摩和耐磨性能均比机械切削加工表面好。据国外资料介绍,▽_6的电火花加工表面可与▽_7的磨削表面的工作性能相当。所
With the rapid development of China’s machinery industry, a variety of new technology continue to emerge. EDM is one of the fastest growing projects, its application is more extensive, especially in the manufacture of various types of molds, more and more to show its superiority. As with machining, surface finish is also an important indicator of EDM. We know that the EDM surface and mechanical cutting the surface is different, it is composed of numerous small pits and smooth small hard protrusions formed, in particular, is conducive to the preservation of lubricating oil, in the same degree of roughness of their anti-friction and wear resistance All better than machined surfaces. According to foreign information, ▽ _6 of the EDM surface with ▽ _7 grinding performance of the work surface is comparable. The
