The ZHONGYUAN DK7780 Wire EDM Machine is a precision computer numerical control (CNC) system designed for high-accuracy electrical discharge machining operations. With an X-axis travel capacity of 31.5 inches (approximately 800mm) and a Y-axis travel of 47.2 inches (approximately 1200mm), this machine accommodates substantial workpieces and complex cutting geometries. The CNC control system enables automated, repeatable machining with minimal operator intervention, utilizing advanced programming capabilities for intricate component production. Wire EDM technology employs a thin electrode wire to cut through conductive materials via controlled electrical discharges, achieving exceptional dimensional accuracy typically within ±0.006mm for straight cuts. The machine operates with variable wire diameters ranging from 0.1mm to 0.3mm, providing flexibility for different application requirements. Standard features include programmable taper angle cutting capabilities, allowing angular cuts up to ±30 degrees, essential for complex part geometries. The working tank system incorporates filtration mechanisms to maintain machining fluid quality and ensure consistent surface finish quality. Typical cutting speeds range from 150-200mm²/min depending on material and wire configuration. The machine delivers surface roughness values of Ra 1.0-2.5μm, meeting stringent precision manufacturing requirements. CNC integration with CAD/CAM software compatibility streamlines the programming process for rapid job setup. The DK7780 represents an industrial-grade solution suitable for tooling, aerospace, medical device manufacturing, and precision component production requiring superior accuracy and repeatability.
