TOPSCNC DK7750Z WIRE EDM MACHINES

Technical Description

The TOPSCNC DK7750Z Wire EDM machine features X-axis travel of 19.69 inches (500 mm) and Y-axis travel of 24.80 inches (630 mm), controlled by CNC for precise operation. It supports a maximum cutting thickness of up to 500 mm with a taper cutting angle of ±6° on 80 mm thickness. The machine operates with a wire diameter range of 0.15 to 0.20 mm, typically using 0.18 mm molybdenum wire, ensuring precise cuts with tolerances as tight as 0.012 mm. The wire speed is adjustable between 5 to 11.4 m/s, with a maximum cutting current of around 6 to 15 A, depending on surface finish and cutting requirements. It achieves cutting speeds of approximately 150 to 300 mm²/min, balancing speed and surface quality, with surface finishes reaching Ra ≤1.6 μm after two cuts. The worktable can support loads up to 800 kg, and the machine weighs around 2300 kg. Standard components include a stepper motor for X/Y axes and a manual Z-axis adjuster, with options for servo motors and motorized Z-axis. The DK7750Z is equipped with a BMW-3000 CNC controller, featuring functions such as taper processing, wire-break handling, power cut memory, automatic edge positioning, and auto-centering. The 100-liter water tank and advanced filtration system ensure stable dielectric cooling. Its robust mechanical design includes high-quality ball screws and steel linear guideways for durability and precision. Overall, the DK7750Z combines large travel capacity, high cutting precision, and reliable CNC control for demanding wire EDM applications.
