BAOMA DK7780I WIRE EDM MACHINES

Technical Description

The BAOMA DK7780I Wire EDM Machine is a high-precision CNC-controlled electrical discharge machining system designed for accurate and efficient cutting of complex shapes in conductive materials. Featuring an X-axis travel of 31.5 inches (800 mm) and a Y-axis travel of 39.4 inches (1000 mm), this machine provides a large working envelope suitable for a wide range of industrial applications, including molds, dies, and precision components. The CNC control system ensures consistent accuracy, with a typical cutting accuracy of ±0.015 mm and the ability to achieve surface roughness values as low as Ra 1.2–2.5 μm depending on process parameters. The machine supports wire diameters from 0.13 mm to 0.2 mm, typically using 0.18 mm molybdenum wire, and can cut materials up to 800 mm thick with a maximum taper angle of ±6°. It delivers a maximum cutting speed of up to 180 mm²/min, with stable performance under continuous operation. The robust construction includes high-precision linear guides and ball screws for smooth axis movement and long-term reliability. The DK7780I is equipped with advanced features such as automatic wire threading, taper cutting, multi-cut capability, and comprehensive protection systems for wire break and short circuit. The control interface is user-friendly, supporting integration with AutoCAD and other design software for seamless programming. Designed for versatility, the machine is ideal for processing tool steels, carbides, magnetic materials, and other hard or exotic metals used in automotive, aerospace, and precision engineering industries.
