JZ DK7735 WIRE EDM MACHINE

Technical Description

The JZ DK7735 Wire EDM Machine is a submerged electrical discharge machining system designed for precision wire cutting with a travel range of 13.78 inches (X-axis), 17.72 inches (Y-axis), and 15.75 inches (Z-axis). It supports a maximum cutting thickness of up to 400 mm and can handle workpiece loads up to 300 kg. The machine features a worktable size of approximately 700 x 440 mm, providing a stable platform for machining complex parts. It operates without auto threading but excels in high-speed cutting, achieving cutting speeds ≥100 mm²/min and a surface roughness ranging from Ra 1.6 to 2.5 µm depending on the cutting mode. The DK7735 supports machining tapers of ±3° standard, with options for up to ±30°, enhancing versatility for angled cuts. It utilizes molybdenum wire with diameters typically between 0.12-0.20 mm and employs a fixed wire feed speed of about 11.5 m/s. Precision is maintained through CNC control and optional digital readout (DRO) systems providing up to 5-micron displacement accuracy. The machine weighs roughly 1300 kg and operates on a 380V, 50Hz power supply. Key design features include independent four-axis control for accurate contouring, ball screw-driven linear guides for smooth motion, and submerged operation for efficient cooling and debris removal. Optional enhancements include linear guides, sheet metal protection covers, and variable speed controllers to tailor performance.
