The SANXING DK7780AZ is a precision wire electrical discharge machine (Wire EDM) engineered for high-accuracy cutting of electrically conductive materials. This CNC-controlled machine features substantial machining capability with an X-axis travel of 47.24 inches, Y-axis travel of 31.50 inches, and Z-axis travel of 17.72 inches, accommodating large and complex workpieces across diverse industrial applications. The machine utilizes advanced wire electrode technology for precise, burr-free cutting with minimal material waste, making it ideal for tool and die manufacturing, aerospace components, and intricate metal parts requiring exceptional dimensional accuracy. The integrated CNC control system enables automated operation and precise positioning, allowing operators to execute complex machining profiles with repeatable precision. Wire EDM machines of this class typically operate using a continuously moving wire electrode that creates a series of controlled electrical sparks to erode material, achieving surface finishes in the range of Ra 0.3–0.4 micrometers. The submerged machining process provides superior surface quality and dimensional stability compared to conventional machining methods. Standard specifications for machines in this category typically include configurable wire diameters ranging from 0.05mm to 0.3mm, enabling both fine detail work and larger volume cutting operations. The machine's generous travel dimensions accommodate workpieces requiring extensive machining zones, while the CNC platform facilitates seamless integration with CAD/CAM programming systems for streamlined production workflows.
