The JZ DK7755 Wire EDM Machine is a precision CNC wire electrical discharge machining tool designed for complex and high-accuracy cutting tasks. It features a substantial work envelope with X-axis travel of 21.65 inches, Y-axis travel of 25.59 inches, and Z-axis travel of 19.69 inches, enabling machining of sizeable conductive components. The machine supports wire diameters from 0.12 mm to 0.18 mm, typically using molybdenum wire, and is capable of cutting thick workpieces up to approximately 500 mm with a maximum load capacity of 800 kg on the worktable. It operates submerged in dielectric fluid, ensuring effective cooling and debris removal during the cutting process. The DK7755 utilizes precise ball screw linear guide rails for smooth, accurate movement, achieving machining precision up to 0.015 mm and cutting speeds exceeding 100 mm²/min. It does not have an auto-threading feature, so wire threading is manual, but it benefits from a stable and robust structure with a machine weight around 2500 kg. The system is powered by efficient AC/DC motors with a total power consumption of about 2 kW on standard 220V or 380V supply. Optional taper cutting ranges from 6° to 60° allow angled cuts to accommodate complex parts. The machine’s dimensions are roughly 2050 mm by 1650 mm by 1700 mm, making it suitable for mid-to-large scale industrial manufacturing environments. Overall, the JZ DK7755 combines reliability, precision, and sizeable capacity for advanced EDM wire cutting applications.
