Pressure vibration method

The pressurized vibration method requires a special machine tool, and the electrode master mold has the opposite shape to the electrode. The graphite material and the forming tool are relatively placed during processing, leaving a certain gap. A processing fluid mixed with water and abrasive is injected into it. The graphite and forming tools are subjected to ultrasonic vibration while passing through the processing fluid. Under the action of the impact of the abrasive, the graphite is stripped into a desired shape.
