BAOMA DK7725B WIRE EDM MACHINE

Technical Description

The BAOMA DK7725B Wire EDM Machine is a high-precision CNC-controlled electrical discharge machining system designed for intricate wire cutting of metal components. It features a 9.84-inch control interface and an XYZ-axis travel that supports a worktable size of 380 x 525 mm with a maximum table load capacity of 300 kg, enabling processing of moderately sized workpieces. The machine employs a high-quality ball screw and steel linear guideways to ensure superior accuracy, achieving positional precision within ±0.015 mm and surface roughness as low as Ra≤2.5 µm after single cutting. Wire diameters range between 0.15 to 0.2 mm, with wire speeds adjustable from 5 to 11 m/s, and the maximum cutting speed can reach 150 mm²/min. The DK7725B supports taper cutting up to ±30° depending on thickness, incorporating advanced taper processing capabilities and diverse shape machining functions. It is equipped with a robust U.S.A Emerson converter and utilizes a BMXP CNC control system enabling direct use of AutoCAD for programming. Additional functionalities include central lubrication, motorized Z-axis movement, short circuit and wire break handling, auto-edge positioning, and power failure memory for processing continuity. The machine weighs approximately 1600 kg, operates on standard 220V/380V power, and uses BM2/BM4 water-based dielectric solutions for effective machining. This combination of precision, functionality, and CNC automation makes the DK7725B suitable for high-precision industrial metal wire cutting applications.
