MACHIMAX DK7720 WIRE EDM MACHINE

Technical Description

The MACHIMAX DK7720 Wire EDM Machine is a precision CNC-controlled electrical discharge machine engineered for intricate metal cutting applications. Featuring an X-axis travel of 7.87 inches (approximately 200mm) and Y-axis travel of 9.84 inches (approximately 250mm), this machine accommodates moderate workpiece dimensions while maintaining excellent positional accuracy. The CNC control system enables automated operation with high repeatability, allowing operators to execute complex cutting patterns and multi-axis machining sequences with minimal manual intervention. This wire EDM utilizes a moving wire electrode, typically ranging from 0.15mm to 0.20mm in diameter, to generate electrical discharges that precisely erode workpiece material. The machine delivers superior surface finishes, achieving Ra values between 1.0-2.5μm in both single and multiple path cutting modes. With cutting accuracy capabilities of ±0.006mm for straight cuts and ±0.015mm for angled cuts, the DK7720 excels in producing tight-tolerance components for aerospace, medical, and tooling industries. The machine supports taper cutting functionality with angles up to ±6° to ±30° per 80mm of thickness, accommodating draft angles for complex geometries. Its robust construction includes a dedicated working tank with efficient filtration systems and adequate coolant capacity to maintain consistent thermal conditions during extended machining operations. The machine operates on standard three-phase electrical supply, making it compatible with typical industrial facilities. The CNC platform facilitates direct CAD file integration, streamlining the path from design to production while reducing setup times and enhancing overall manufacturing efficiency.
