TOPSCNC DK7763Z WIRE EDM MACHINES

Technical Description

The TOPSCNC DK7763Z is a high-speed wire electrical discharge machine (EDM) designed for precision metal cutting applications. This CNC-controlled system features X-axis travel of 24.8 inches and Y-axis travel of 31.5 inches, providing a generous working envelope with a table size of 750×1140mm accommodating workpieces up to 2400kg. The machine delivers exceptional machining speeds exceeding 200mm²/min with wire diameters ranging from 0.15-0.20mm (recommended 0.18mm) and adjustable feeding speeds of 1-11.4m/sec. Precision is maintained at ≤0.015mm with surface roughness achieving Ra≤2.5μm, meeting stringent dimensional accuracy requirements. The DK7763Z utilizes a 4-axis simultaneous control system with stepper motors for X, Y, U, and V axes, featuring a minimum control pace of 0.001mm. It supports maximum taper angles of ±6°/80mm for angled cutting operations. Powered by a 3N-380V/50Hz supply with 1kW consumption and 12A maximum working current, the machine incorporates a 55-liter water tank with filter screen system using JA-1 working fluid. The manual Z-axis control with slide guide construction ensures stable operation for various production requirements, making it ideal for high-precision components across automotive, aerospace, and tooling industries.
