TOPSCNC DK7763ZF WIRE EDM MACHINES

Technical Description

The TOPSCNC DK7763ZF Wire EDM machine features a robust CNC control system designed for high precision wire electrical discharge machining. It offers an X-axis travel of 24.8 inches (630 mm) and a Y-axis travel of 31.5 inches (800 mm), enabling processing of larger workpieces up to 550 mm thickness with a maximum taper angle of ±6° per 80 mm. The wire diameter ranges from 0.15 to 0.20 mm, with a recommended 0.18 mm wire size. The feeding speed is adjustable between 1 to 11.4 m/s, supporting a machining speed above 200 mm²/min and a precision of ≤0.015 mm, providing fine detail and surface roughness of Ra ≤2.5 μm. The machine uses stepper motors for X, Y, U, and V axes, enabling four-axis simultaneous control with a minimum control increment of 0.001 mm. The Z-axis is electronically controlled and guided by slide guides. Its water-based dielectric fluid ensures stable and efficient cutting, supported by a standard 55-liter water tank. The DK7763ZF weighs approximately 2,900 kg and measures 2250×2250×2150 mm, providing a solid steel structural frame for stability and durability. Its 3-phase voltage operation (3N-380V/50Hz) with about 1 kW power consumption supports industrial-level electric discharge machining requirements. Control features include automatic taper processing, backlash and wire break handling, edge positioning, auto-centering, and memory functions for power interruptions, facilitating ease of operation and high productivity in precision manufacturing environments.
