模具电火花加工质量的好坏,在很大程度上取决于电火花加工电源的好坏。这在加工高精度型腔模时尤其突出。如何评定电火花加工电源性能的好坏呢?外表的美观、操作的自动化程度、加工速度的高低以及表面粗糙度的大小等固然是反映电源性能好坏的诸多方面,但笔者认为,质量的至为重要的因素是电源的电极损耗性能的优劣。如果某电源的电极损耗性能好,它只需用一个电极即可加工出一个或几个工件。反之,它将用 Mold EDM quality is good or bad, largely depends on the EDM power supply is good or bad. This is especially true when machining high-precision cavity molds. How to assess the performance of EDM power good or bad? The aesthetic appearance, the degree of automation of the operation, the level of processing speed and the size of the surface roughness, of course, reflects the power performance of many aspects, but I believe that the quality of An important factor is the pros and cons of the electrode’s loss performance. If a power supply electrode loss performance, it can use only one electrode can be machined out of one or several pieces. On the contrary, it will use
