Electrical discharge machining has the following characteristics

Machinable hard materials: Electric discharge machining can process hard materials, such as quenched steel, hard alloys, etc.
No cutting force: During the discharge machining process, no cutting force is required, so there is no vibration or noise generated.
High precision: The precision of discharge machining is very high, which can be controlled at the micron or even nanometer level.
Machinable complex shapes: Electrical discharge machining can be used to process parts with complex shapes.
Slow processing speed: Compared to traditional mechanical processing methods, the speed of discharge machining is relatively slow.
High energy consumption: Electrical discharge machining requires a large amount of electrical energy consumption.
Professional operational skills are required: Electric discharge machining requires operators to possess certain skills and experience, otherwise it can easily cause misoperation and waste.
