GLMTC DK7740 WIRE EDM MACHINES

Technical Description

The GLMTC DK7740 Wire EDM Machine is a high-precision CNC-controlled electrical discharge machining system designed for accurate and efficient cutting of conductive materials. Featuring a robust construction and advanced control technology, this machine delivers reliable performance for a wide range of industrial applications. The working table offers an X-axis travel of 24.7 inches (630 mm) and a Y-axis travel of 15.7 inches (400 mm), providing ample workspace for medium to large workpieces. The machine is equipped with an auto-threading function, enhancing operational efficiency and reducing downtime during wire changes. The CNC control system ensures precise parameter adjustment and seamless integration with modern CAD software, supporting complex cutting patterns and multi-axis operations. The DK7740 utilizes a molybdenum wire electrode with a typical diameter range of 0.12 mm to 0.18 mm, allowing for fine detail and high surface finish. Maximum cutting thickness reaches up to 400–500 mm, accommodating a variety of part sizes. The machine achieves a maximum cutting speed of over 100 mm²/min, with surface roughness as low as Ra ≤ 2.5 μm, ensuring high-quality results. The system incorporates a stable power supply, efficient filtration, and protective features such as wire break detection and automatic stop. Designed for ease of use and maintenance, the DK7740 features a user-friendly interface, automatic edge finding, and memory functions for interrupted processes. Its compact footprint and low noise operation make it suitable for diverse workshop environments, delivering consistent accuracy and productivity for demanding EDM applications.
