用放电磨削法高效磨削难加工材料明治大学理工学院横川教授等研制了一种高效磨削难加工材料的放电磨削法。这种磨削方法的机理，是将放电电极的阳极与导电的砂轮相接，而将阴极与被磨削的工件相接。这种磨削方法，由于在砂轮与工件间施加电压，在磨削过程中产生放电现象，... Efficient grinding of hard-to-cut materials by discharge grinding method Professor Yokogawa of the Faculty of Science and Technology at Meiji University has developed a discharge grinding method that efficiently grinds difficult-to-machine materials. The mechanism of this grinding method is to connect the anode of the discharge electrode to the conductive grinding wheel and connect the cathode to the workpiece to be ground. This grinding method, due to the application of voltage between the grinding wheel and the workpiece, the discharge process in the grinding process, ...
