TOPWEDM DK7750J WIRE EDM MACHINE

The TOPWEDM DK7750J is a precision wire electrical discharge machine (EDM) engineered for high-accuracy cutting of conductive materials. Featuring CNC control with advanced servo motor technology, the machine delivers consistent machining performance across diverse industrial applications. The three-axis travel system provides substantial working envelope with 19.69 inches of X-axis travel, 31.50 inches of Y-axis travel, and 15.75 inches of Z-axis travel, accommodating moderately-sized workpieces. The machine utilizes precision wire electrodes ranging from 0.004" to 0.012" diameter, enabling fine detail work and complex geometric cuts. Wire EDM technology generates controlled electrical discharges between the wire and workpiece, achieving tolerances as tight as ±0.0002" through multi-pass finishing techniques. The submerged machining environment protects components while facilitating efficient spark erosion. Advanced flushing systems manage dielectric fluid pressure to minimize wire deflection and maintain dimensional accuracy. The machine's fiber optic servo control enables rapid internal communication speeds, enhancing operational efficiency and precision. CNC programming capability allows automated sequencing for complex part geometries, reducing setup time and improving repeatability. The DK7750J is particularly suited for producing stamping dies, fine blanking tools, and precision components requiring superior surface finish qualities below Ra 1.5 microns. Capable of machining hard materials that prove difficult for conventional machining methods, this wire EDM system represents an investment in precision manufacturing for demanding aerospace, medical device, and tool-and-die applications requiring exceptional accuracy and repeatability.
