用电火花加工横具是一项新工艺,电火花机床是此项新工艺的专用设备。近年来,不少单位的职工,以毛泽东思想为武器,发扬自力更生,奋发图强的精神,先后制出了各种类型的新机床。其中尤以大功率、高生产率的高频电源最为理想。用这类机床来加工一个凹模,一般只需多30分钟至一小时。 EDM is a new process, EDM machine is a special equipment for this new process. In recent years, employees of many units have used Mao Tse-tung’s thoughts as their weapons, carried forward the spirit of self-reliance, and worked hard to make them strong. They have successively produced various types of new machine tools. Among them, high-power and high-productivity high-frequency power supplies are ideal. It takes only 30 minutes to an hour for a die to be machined with this kind of machine.
