SHEM DK7740ZF WIRE EDM MACHINE

Technical Description

The SHEM DK7740ZF Wire EDM Machine is a high-precision CNC-controlled electrical discharge machining system designed for efficient and accurate cutting of conductive materials. Featuring an X-axis travel of 19.69 inches (500 mm) and a Y-axis travel of 15.75 inches (400 mm), this machine provides a robust work envelope suitable for a wide range of industrial applications. The CNC control system ensures precise, repeatable cuts with a positioning accuracy of up to ±0.015 mm, making it ideal for intricate and complex part geometries. The machine supports electrode wire diameters from 0.15 mm to 0.20 mm, with a recommended wire size of 0.18 mm, and offers adjustable wire feeding speeds from 1 to 11.4 m/sec for optimized cutting performance. With a maximum cutting speed exceeding 220 mm²/min, the DK7740ZF delivers high productivity without compromising on surface finish, achieving a minimum surface roughness of Ra ≤1.2 μm with multiple cuts. The machine is equipped with advanced features such as taper cutting, automatic wire threading, and comprehensive protection systems for wire breakage and short circuits. Its sturdy construction supports a maximum workpiece weight of up to 500 kg, and the large working tank ensures stable machining conditions. The DK7740ZF weighs 3527.4 lbs (1600 kg), reflecting its heavy-duty build and reliability for continuous industrial use. This machine is well-suited for mold making, tooling, and precision component manufacturing where accuracy, speed, and reliability are critical.
