Electric discharge molding machine is a special machining method that uses the electrochemical erosion generated by the pulse discharge between the two electrodes immersed in the working fluid to remove conductive materials. It is also known as discharge machining or electrochemical erosion machining, abbreviated as EDM, and is widely used in the manufacturing of various metal molds and mechanical equipment. 1. The precision CNC electric spark forming machine first checks that the main power switch is ON. 2. Install the electrode and clamp, calibrate the verticality and parallel reference, place the workpiece on the magnetic work table, calibrate the parallel reference, and fix it by magnetic attraction. CNC electric spark forming machine 3. Use electrodes to search for the discharge position X.Y coordinates of the workpiece, and set AT 詷 to OA, PA20 during edge searching μ S~45 μ S. 4. Polarity selection, with copper as the positive electrode and the workpiece as the negative electrode. 5. Current AT adjustment, combination of discharge event PA, rough (electrode unilateral gap 0.12) ATS-45A, PA60s~120 μ s. The specific conditions depend on the size of the discharge electrode area. If the discharge area is relatively small, it can be roughly used with 1.5A90 μ S (less than 1mm2) to avoid excessive electrode loss; Fine discharge (electrode unilateral gap 0.04), AT1.5~SA.PA20 μ S~60 μ s. When the discharge area is large, use AT1.5PA60 first μ Switch to AT3A.PA30 when lowering the side wall to around 0.1 μ S left 0.030, then switched to AT1.5A.PA30 μ Set S to 0.005, and finally trim 0.025 on one side (AT1.5APA30 μ S) . CNC electric spark forming machine 6. Stop event PB, adjust discharge gap voltage. When coarse, adjust PB3-4, gap voltage to 3 or 4, when fine repair, adjust PB to 5 or 6, and gap voltage to 5 or 6. 7. Servo strength, check the setting of the motion. When coarse, adjust the servo to 6 or 7, and set the up and down motion events of the machine head to 54 or 44, respectively. When fine laying, adjust the servo to 5, and set the up and down inspection time of the machine head to 52 or 63 respectively. 8. Turn on the liquid level control switch (the indicator light flashes when turned on), and turn on the sleep switch (the indicator light lights up when turned on). CNC electric spark forming machine 9. Manual servo feed, reach the Z-axis reference plane position, set the precision CNC spark machine discharge depth. When setting the depth, input data at the moment when the electrode and workpiece are completely in contact, and then adjust the Z-axis based on the difference. (Do not press down the F1 switch to set the depth). 10. Process the hydraulic motor ON and adjust the flushing position. 11. Discharge switch ON
