The BAOMA DK7740D-C Wire EDM Machine is a high-precision CNC-controlled electrical discharge machining system designed for accurate cutting of complex metal parts and molds. Featuring a robust construction and advanced control technology, it ensures smooth operation and reliable performance in industrial environments. The machine offers a travel distance of 15.75 inches (400 mm) along the X-axis and 19.69 inches (500 mm) along the Y-axis, enabling the processing of medium to large workpieces with ease. Its CNC control system provides precise command over all machining parameters, supporting automated cutting sequences and consistent repeatability. The DK7740D-C is equipped with an adjustable wire guide frame and supports wire diameters from 0.15 to 0.2 mm, allowing for fine detail work and high surface finish quality. Maximum workpiece thickness is 500 mm, and the machine can achieve a maximum taper angle of ±3° for parts up to 100 mm thick. Typical cutting speed reaches up to 120 mm²/min, with a precision of ±0.015 mm and surface roughness as low as Ra 1.5 μm after three cuts. The system operates on a 3N-380V/50Hz power supply with a rated power consumption of 3 KVA and includes a working solution reservoir of 56 liters. The machine’s dimensions are 1500×1000×1850 mm (L×W×H), and it weighs 2000 kg, making it suitable for stable, heavy-duty applications. With its combination of CNC automation, high accuracy, and versatile cutting capabilities, the BAOMA DK7740D-C is ideal for precision manufacturing in tool and die, aerospace, and automotive industries.
