EDM is an equipment that many processing manufacturers use, and ordinary materials cannot use it. Only more complex materials will use EDMs, and many manufacturers are more concerned about how to make the equipment correct for a long time. Work, the following is what companies want to know.
According to the need for processing or oil immersion, turn on the electric switch for processing. For electric discharge, such as small currents or processing areas, if there is no protection when immersed in oil, immerse the mold to 50mm or more than oil immersed multiple electrodes; open current output, Cooperate with the servo adjustment knob of the punch, usually with 200V voltmeter unit 70, low voltage refers to 40-50 0 voltmeter, high pressure refers to 280V voltmeter 120-130, high frequency current adjustment.
When processing large workpieces, add cushions on the worktable to prevent the mold from slotting during lifting; when discharging, use the operating rules to correctly fix the processing object and electrode; it is not allowed to touch the electrode part of the mold by hand during discharge; Before, the cooling oil should be adjusted and processed first, and a carbon dioxide fire extinguisher should be prepared next to the machine for use in case of misoperation and ignition. The electrode is too small and the diameter is within 6mm. It is not allowed to turn on excessive current to avoid electrode consumption.
Before using the EDM machine to process the fluid barrel, check the inventory of the working fluid and insist that it is above 90%. If there is an abnormal state, the first thing to do is to cut off the power, and then check whether it is caused by improper operation, and then check whether the equipment itself is malfunctioning.
