ZHONGYUAN DK-7750A WIRE EDM MACHINE

Technical Description

The ZHONGYUAN DK-7750A Wire EDM Machine is a precision CNC-controlled electrical discharge machine designed for high-accuracy metal cutting applications. Featuring an X-axis travel of 19.69 inches and Y-axis travel of 24.80 inches, this machine provides substantial working envelope for medium to large workpieces. The system employs a thin metal wire as the cutting electrode, utilizing electrical discharge technology to cut through hardened and difficult-to-machine metals with exceptional precision. The DK-7750A incorporates a BMXP CNC control system operating on Windows XP platform, enabling direct CAD integration for seamless design-to-production workflows. The machine supports simultaneous control of four axes, allowing complex tapered cuts and multi-directional machining capabilities. Wire diameter specifications range from 0.15 to 0.2mm, with adjustable feed speeds of 5-11 m/s, accommodating various material thicknesses and surface finish requirements. Key technical specifications include a maximum cutting speed of 150 mm²/min and maximum working current of 6A, delivering surface roughness as fine as 1.2 micrometers. The machine utilizes a central lubrication system and high-precision linear guide ways to maintain accuracy throughout extended cutting operations. Maximum cutting thickness reaches 500mm with taper capabilities up to ±30°, making it suitable for complex component production. The modular internal wiring design minimizes failure probability while facilitating maintenance access. The system requires 3-phase 380V power supply at 50Hz and operates optimally in clean, vibration-free environments with controlled humidity levels between 40-80%, ensuring consistent cutting performance and dimensional accuracy across production runs.
