BAOMA DK7725 WIRE EDM MACHINES

Technical Description

The BAOMA DK7725 Wire EDM Machine is a high-precision CNC-controlled wire electrical discharge machine designed for efficient and accurate metal cutting. It features an X-axis travel of 9.84 inches and a Y-axis travel of 12.6 inches, allowing for precise handling of workpieces up to 300-500mm in thickness depending on the variant. The machine uses a high-quality linear guide system and a U.S.A Emerson converter to ensure stable and smooth operation. It supports wire diameters from 0.10 to 0.20 mm with wire traveling speeds between 5 to 11.5 m/s, providing cutting speeds of up to 120-150 mm²/min. Its control system is CNC-based, often integrated with BMXP or BMW-3000 software allowing direct programming from AutoCAD. The DK7725 accommodates complex taper cutting, with angles up to ±30°, and offers multiple functions including automatic wire break handling, auto-centering, and memory for power interruptions. The machine operates on a 3-phase 380V power supply, consuming less than 1.5 kW, and uses a water-based emulsion as the working fluid for cooling. Surface finish quality can reach Ra ≤ 2.5 μm in single cuts, improving with multiple passes. The worktable supports loads up to 200-300 kg, with overall machine dimensions around 1485×1010×1400 mm and weights up to 1600-2300 kg depending on configuration. Central lubrication and automatic wire tension systems enhance longevity and maintenance ease, making the DK7725 suitable for high-speed, high-accuracy wire EDM applications in tool and mold making industries.
