DK7730 High Speed Wire Cut EDM Machine

The DK7730 high-speed CNC wire-cut EDM machine is a mature and widely utilized piece of electrical discharge machining (EDM) equipment in the precision mold and mechanical machining industries. It employs molybdenum wire as the electrode, utilizing high-frequency pulse discharges to generate instantaneous high temperatures that melt and erode metal material, thereby achieving the desired cutting shape. Unlike traditional mechanical cutting, this wire-cut process involves no rigid contact pressure or tool wear, and the workpiece remains unaffected by cutting forces; these characteristics make it a core tool for machining complex, high-precision, and difficult-to-machine metal parts.
The machine features a mechanically sound and highly rigid main structure, laying a solid foundation for long-term, stable operation. It is equipped with high-precision ball screws and linear guideways, utilizing a direct-drive screw configuration and automatic backlash compensation. This design effectively eliminates transmission backlash, ensures smooth and precise axial movement, and maintains consistent machining accuracy during prolonged, continuous cutting operations. With a standard table travel of 300×360 mm, a maximum cutting thickness of 400 mm, and a load capacity of 200 kg, it meets the machining requirements for the vast majority of conventional small-to-medium precision workpieces. Additionally, the machine supports ±6° taper cutting (extendable to 45° via custom configuration), enabling the single-pass machining of tapered surfaces, inclined holes, and complex geometric components.
In terms of performance, the DK7730 strikes a balance between high speed and high precision. It achieves a maximum cutting speed of 100 mm²/min, significantly boosting batch processing efficiency compared to standard low-speed wire-cut machines. An optimized pulse power supply and specialized frequency converter accelerate material removal while reducing energy consumption and operating noise, facilitating energy-efficient production. Overall machining accuracy is controlled within 0.015 mm, with an optimal surface roughness of Ra 2.5 μm. A closed-loop control system—equipped with 1 μm high-precision linear scales—enables real-time positioning and pitch error compensation, effectively preventing dimensional deviations caused by mechanical deformation and ensuring exceptional repeatability.
