The TOPWEDM DK7780D is a precision CNC wire electrical discharge machine engineered for high-accuracy metal cutting applications. This machine features substantial travel dimensions with 31.5 inches (800mm) on the X-axis, 39.4 inches (1000mm) on the Y-axis, and 31.5 inches (800mm) on the Z-axis, enabling processing of large workpieces. The system utilizes a computerized numerical control (CNC) platform for automated, repeatable machining operations with exceptional dimensional accuracy. The wire EDM technology employs a thin electrode wire—typically ranging from 0.1 to 0.3mm in diameter—alongside deionized water as a dielectric medium to cut through hardened and exotic metals with minimal thermal distortion. The DK7780D delivers cutting speeds up to 200mm²/min with cutting accuracy as tight as ±0.006mm for straight cuts, meeting demanding precision requirements. The machine supports angular cutting capabilities with taper angles up to ±30°, providing versatility for complex part geometries. Equipped with a heavy-duty construction, the machine incorporates a precision working table with substantial load capacity, typically accommodating workpieces up to 1000kg. The integrated filtration system with 0.005mm changeable filters maintains optimal working fluid conditions for consistent performance. Power requirements include 3-phase 380V/50Hz electrical supply, with maximum cutting current specifications around 7A. The machine's modular design and Windows-based CNC system enable seamless integration with CAD software, facilitating direct part programming and multi-axis simultaneous control for enhanced productivity and accuracy in precision manufacturing environments.
