CONCORD DK7725 WIRE EDM MACHINE

Technical Description

The CONCORD DK7725 Wire EDM machine is a CNC-controlled precision wire electrical discharge machine designed for detailed cutting and contouring of small to medium conductive components. It features an X-axis travel of 9.84 inches and a Y-axis travel of 12.60 inches, accommodating workpieces within these movement ranges. The machine weighs approximately 353 lbs, making it compact yet robust for workshop environments. Its CNC system ensures high accuracy with positional resolution typically around 0.015 mm, supporting complex shape programming, often via AutoCAD integration. The machine employs a high-quality ball screw and steel linear guideways for smooth, precise motion, with a maximum cutting speed typically up to 150 mm²/min. It uses fine wire electrodes with diameters typically ranging from 0.12 mm to 0.2 mm, controlled via adjustable wire guides. The DK7725 supports multi-cutting modes for enhanced surface finish, achieving surface roughness below 2.5 microns after a single pass and even finer with multiple passes. It operates with power around 1.5 to 1.8 kW, supplied from standard industrial voltages (220-415 VAC, 50/60 Hz). The system includes features such as automatic program stop, incremental programming, and compatibility with Windows-based software environments, supporting both manual and automatic Z-axis adjustments. Its design allows for precise taper cutting with an angle tolerance up to ±3° for thicknesses up to 300 mm. Typical applications include mold making, tool and die production, and intricate component fabrication across various industries.
