GLMTC DK7732 WIRE EDM MACHINE

Technical Description

The GLMTC DK7732 Wire EDM Machine is a CNC-controlled electrical discharge machining system designed for precision cutting of conductive materials. It features a worktable travel of 15.7 inches (X-axis) by 12.5 inches (Y-axis), supporting a maximum cutting thickness up to approximately 500 mm depending on configuration. The machine supports automatic wire threading and uses molybdenum wire electrode diameters ranging from 0.10 to 0.20 mm, with wire speeds up to about 11.5 m/s for efficient and precise cutting. It achieves a cutting speed of approximately 90-150 mm²/min with excellent surface finish quality, typically reaching surface roughness values as low as Ra 1.2–2.5 μm. The DK7732 incorporates a linear guide with precision ball screws and closed-loop glass scales, providing positional accuracy within 0.005–0.015 mm. The machine allows taper cutting from ±6° up to ±30°, enabling complex tapered features. Its structural design includes a rigid frame with electric lift adjustment for the guide wheels and a large capacity work tank with filtration to maintain cutting stability and quality. The system uses a CNC controller with Windows-based software compatible with CAD/CAM integrations, enabling multi-cut functions and file translation. Power supply for the DK7732 is typically 3-phase AC 380V/220V with power consumption below 3 kW. The machine dimensions are roughly 1640×1280×1700 mm, weighing around 1400 kg. It is suitable for high-accuracy, medium to high-speed wire EDM operations in manufacturing and repair environments.
