BAOMA DK7740C-CS WIRE EDM MACHINE

Technical Description

The BAOMA DK7740C-CS is a precision CNC wire electrical discharge machine designed for high-accuracy metal cutting applications. This machine features an X-axis travel of 19.69 inches (500mm) and Y-axis travel of 31.50 inches (800mm), providing substantial work envelope capacity for medium to large-scale components. The CNC control system enables automated, repeatable cutting operations with minimal operator intervention, utilizing Windows-based software integration for seamless CAD file compatibility. This wire EDM machine employs a thin electrode wire, typically ranging from 0.15mm to 0.20mm in diameter, to achieve precision cuts through electrical discharge erosion. The system operates with a maximum cutting current of approximately 6-7 amperes and delivers cutting speeds up to 200mm²/min, depending on material thickness and complexity. The machine maintains exceptional cut accuracy of ±0.006mm for straight cuts and ±0.015mm for angle cuts, ensuring tight tolerances suitable for die-making, aerospace, and medical device applications. The DK7740C-CS incorporates advanced servo control mechanisms and high-precision linear guideways to support workpieces weighing up to 1000kg on its working table. It accommodates taper cutting angles up to ±30° with pitch compensation for complex geometries. The machine includes a 60-liter working fluid tank with 0.005mm filtration capacity to maintain optimal machining conditions. Power requirements include three-phase 380V/50Hz supply at approximately 3KVA rated power. The complete system weighs approximately 6000kg with overall dimensions of 2700×1800×2300mm, making it suitable for professional machine shops requiring reliable precision cutting capabilities.
