The TOPSCNC DK7750ZF is a high-precision CNC Wire EDM machine designed for efficient and accurate wire cutting applications. It features an X-axis travel of 19.69 inches (500 mm) and a Y-axis travel of 24.80 inches (630 mm), providing ample working area for diverse workpieces. The machine supports a workpiece thickness up to 400 mm and can handle weights up to 400 kg. It operates with a CNC control system, offering precise cutting accuracy up to 0.01 mm, ensuring excellent dimensional fidelity and surface finish. The wire diameter range is 0.15 to 0.20 mm (commonly 0.18 mm), with adjustable wire feed speeds between 1 to 11.4 m/s, which allows optimization of cutting speed and surface quality. The DK7750ZF supports a maximum working current of 6-12 A, enabling cutting speeds of approximately 150-300 mm²/min depending on the material and finish requirements. Its frame integrates high-quality ball screws and steel linear guideways for stable, precise movement. The machine weighs around 2300 to 2500 kg and runs on a 3N-380V/50Hz power supply with about 1 kW power consumption. Additional features include adjustable wire guide frames, water-based working solutions, a 55-100 L water tank with filtration, and multi-axis simultaneous control for complex taper cutting up to ±6° over 80 mm thickness. Optional motorized Z-axis and digital readout (DRO) can enhance productivity and ease of operation. The DK7750ZF is suitable for industries requiring intricate and fast wire EDM cutting with reliable precision and repeatability.
