At Suzhou Talent Import and Export Co., Ltd., learn more about the operating instructions for EDM punching machines.

.

I、Before operation calibration:

1. Check whether the operating system of the power panel of the small hole EDM machine operates normally.

2. Loosen all buttons on the panel.

3. Set the switches of all knobs to 0.

4. Determine the size of the machining hole, select the corresponding electrode, and then select the spring clamp and seal ring to clamp the electrode on the screw head,the clamping force shall be appropriate.

5. Select the corresponding processing parameters according to the processing parameter recommendation table.

6. Connect the positive electrode of the processing power supply with the workpiece by clamping any fitting.

7. Shake the hand wheel of the spindle head of the small hole EDM machine to keep the distance between the workpiece and the guide at 3-5 mm, and then swing the hand wheel to push the electrode to the predetermined position.

8. Select a guide suitable for the electrode, install it in the guide frame, and then pass the electrode through the guide and fix it.
