BAOMA DK7732C WIRE EDM MACHINES

Technical Description

The BAOMA DK7732C Wire EDM Machine features a CNC control system based on Windows XP with BMXP software, enabling seamless data exchange, remote control, and pitch correction for enhanced positioning accuracy. It has an X-axis travel of 16.34 inches (approximately 415 mm) and a Y-axis travel of 25.00 inches (approximately 635 mm), supporting a worktable load capacity of 400 kg and a maximum workpiece thickness of up to 300 mm. The machine body uses resin-sand cast technology with high-temperature annealing for distortion resistance, while the travel components utilize high-quality ball screws and linear guideways for precision movement. The wire frame’s symmetric design maintains consistent molybdenum wire tension, controlled by a stable Emerson inverter system from the USA to minimize wire breakage. It achieves a positioning precision of ≤ 0.015 mm and a maximum cutting speed of 150 mm²/min with a working current up to 6 A and rated power of 3 KVA. The wire diameter ranges from 0.15 to 0.2 mm, and typical surface roughness after cutting is ≤ 1.5 µm, which can be further improved using BM working solutions. The cooling system includes a large 100 L reservoir with a three-level filtration system to ensure stable operation. The machine supports CNC programs compatible with AutoCAD and stores large data sets via its extensive database. Total machine weight is around 1700 kg, with dimensions approximately 1450×1000×1550 mm, reflecting a robust build suited for high-precision, high-speed EDM wire cutting applications in mold making and fine machining.
