TOPSCNC DK7780Z WIRE EDM MACHINE

Technical Description

The TOPSCNC DK7780Z Wire EDM Machine features an X-axis travel of 31.5 inches and a Y-axis travel of 39.4 inches, controlled via CNC for high precision operations. It supports workpiece thicknesses up to 800 mm with a maximum taper angle of ±6° over 80 mm, enabling complex tapered cutting. The machine employs high-quality ball screw and steel linear guideways for stability and accuracy. It uses a wire diameter range of approximately 0.12 to 0.20 mm, commonly 0.18 mm, with a maximum cutting current around 10–15 A, delivering cutting speeds up to 300 mm²/min under ideal conditions. Surface finish quality can reach Ra ≤ 2.3 µm on a single pass, with improved finishes possible over multiple cuts. The worktable measures approximately 850 × 1000 to 1500 mm, with a load capacity near 2000 kg, supporting substantial workpieces. The CNC controller supports 4-axis simultaneous control and offers advanced functions including taper processing, edge auto-centering, short circuit and wire-break handling, and memory recovery after power loss. The machine runs on a three-phase power supply (220–415 V, 50/60 Hz) with power consumption around 1–3 kVA and is designed for stability in industrial environments with features protecting against wire burnout and electrical discharge irregularities. It is capable of precision machining of punch dies, molds, and complex 2D/3D components with a versatile range of applications in electronics, precision tools, and metalworking industries. The working tank capacity is roughly 60 to 100 liters, using water-based dielectric solutions for EDM cutting. Overall, the DK7780Z models provide robust, high-accuracy wire EDM capabilities for industrial precision manufacturing.
