Product Description

Wide Applicable Materials

Electrical discharge machining has unique advantages for superhard materials: mold steel and tool steel with hardened steel HRC55-65, which are difficult to process by conventional cutting, can be easily completed by EDM; cemented carbide YG and YT with hardness HRA85-92, precisely formed by EDM; titanium alloy TC4 with poor thermal conductivity and serious work hardening, no cutting force and no deformation by EDM; nickel-based superalloy GH4169 with good heat resistance and difficult cutting, high efficiency by EDM; stainless steel, copper alloy, conductive ceramics and other materials can be processed. Processing objects: mold cavity, narrow slit, special-shaped hole, complex surface.
