混粉加工是指借助于特殊的过滤系统、控制软件及辅助系统 ,在电火花加工工作液中添加某些粉剂材料进行加工的方法。采用这种加工方法可以在更短的时间内加工出更优质量的工件表面。一些机床制造商已先后开发出混有硅、铬、铝等粉末的工作液 ,而日本牧野公司推出的一种名为 μＳ Mixing processing refers to the use of special filtration systems, control software and support systems, EDM working fluid to add some powder material for processing methods. Using this method of processing can be processed in a shorter period of better quality of the workpiece surface. Some machine tool builders have successively developed a working solution mixed with silicon, chromium, aluminum and other powders, while the Japanese Makino company introduced a called μS
