High machining precision: It can achieve a high level of dimensional accuracy, usually controlled within ±0.01mm. Even on some high-precision equipment, it can reach ±0.001mm, which can meet the machining requirements of various precision parts.

Capable of machining complex shapes: Through the precise control of the movement trajectory of the electrode wire by the numerical control system, it can machine various complex two-dimensional and three-dimensional shapes, such as various special-shaped holes, molds with complex contours

Strong material adaptability: It can machine various conductive materials, including cemented carbide, quenched steel, copper, aluminum, etc. No matter how high the hardness of the material is, as long as it is conductive, it can be machined. This is a great advantage for high-hardness materials that are difficult to process by traditional mechanical machining methods

Good surface quality: During the machining process, due to the concentrated discharge energy and small heat-affected zone, the surface roughness of the workpiece can usually reach Ra0.8 - Ra3.2μm, with good surface quality, which can reduce subsequent machining processes

Small machining allowance: The diameter of the electrode wire is usually very thin, generally between 0.1 - 0.3mm. Only a small amount of material needs to be removed during machining, which can effectively save raw materials, especially important for the machining of precious materials
