CONCORD DK7750 WIRE EDM MACHINE

Technical Description

The CONCORD DK7750 Wire EDM machine features CNC control with precise X and Y axis travels of 19.69 inches and 24.80 inches, respectively, enabling high-accuracy wire cutting operations. It integrates a BMXP CNC control system running on a Windows XP platform, supporting direct AutoCAD program input for seamless design-to-cut workflows. The machine is equipped with high-precision linear guides and an auto wire tension system to maintain cutting stability and accuracy, achieving a machining tolerance down to 0.01 mm. It supports wire diameters from 0.13 mm to 0.2 mm and can handle cutting speeds up to approximately 150–180 mm²/min depending on process settings. The DK7750 can manage complex taper cuts up to ±30° over 100 mm thickness and features advanced functions such as multi-cut options, auto edge positioning, auto-centering, and short circuit/wire-break handling. It uses a central lubrication system for reduced maintenance and includes a 100L water-based work solution tank for effective flushing. The machine weighs approximately 507 lbs, reflecting a compact design for its capabilities. Rated power consumption is around 1–3 kVA from a 3-phase 220-415V supply. The DK7750 supports workpiece thicknesses up to at least 500 mm and wire speeds adjustable between 5 and 11 m/s. Additional features include a motorized Z-axis adjustment, graphical display of wire position, and database optimization for cutting variable shapes and tapers, ensuring high-precision and efficiency in wire EDM operations. This machine is tailored for applications requiring detailed, precise metal cutting with flexible taper and surface finish capabilities.
