KINGRED DK7740 WIRE EDM MACHINES

Technical Description

The KINGRED DK7740 is an economical CNC wire cut EDM (Electric Discharge Machine) designed for precision cutting of conductive materials. This medium-sized machine features a 400×500mm worktable travel distance, equivalent to 15.75 inches (X-axis) and 19.69 inches (Y-axis), providing adequate workspace for various component sizes. The machine delivers a maximum cutting speed of 150-160 mm²/min with exceptional precision of ≤0.015-0.02mm, meeting GB7926-2005 standards. The DK7740 utilizes a wire electrode with a diameter of 0.15-0.2mm and operates at wire speeds between 5-11 m/s, powered by a maximum working current of 6A. It accommodates cutting thicknesses up to 500mm with standard taper capabilities of ±3° or optional configurations up to ±30°. The machine employs a BM2/BM4 water-based working solution for optimal erosion control and surface finish, achieving surface roughness as low as 1.0-1.2μm. The CNC control system utilizes the BMW-3000 controller with BMXP PM-K system software, operating on Windows XP platform with seamless integration to CAD software like AutoCAD. The unit operates at AC 220-415V, 50/60Hz with a rated power of 3 KVA and includes a 100L water tank for cooling and flushing. Advanced features encompass automatic edge positioning, taper processing, wire-break handling, power-cut memory functions, and multi-cutting capabilities, making it suitable for precision die and mold work.
