The SANXING DK77100AZ is a precision wire electrical discharge machine designed for high-accuracy machining of conductive materials. This CNC-controlled system features substantial travel distances with 47.24 inches (1200mm) along the X-axis, 39.37 inches (1000mm) along the Y-axis, and 17.72 inches (450mm) along the Z-axis, enabling machining of large workpieces. The machine utilizes wire electrode technology with typical diameters ranging from 0.05mm to 0.3mm, providing versatility for both general cutting and precision applications. Wire EDM machines like this operate through electrical discharge, creating sparks between the wire electrode and workpiece in a controlled dielectric fluid environment, achieving superior surface finishes and dimensional accuracy. The CNC controller enables simultaneous multi-axis interpolation (X, Y, Z, U, V), allowing for complex geometries including tapered cuts and intricate internal features. Machining accuracy is controlled through precise management of cutting parameters—power, frequency, and fluid flushing rates—with modern systems capable of achieving tolerances of 0.005mm or better and surface roughness under Ra 0.5 microns. The submerged machining capability protects the wire and workpiece while improving cut quality. Auto-threading functionality reduces operator intervention, and servo motor technology maintains consistent wire tension for reliable performance. This machine class is ideal for die and mold manufacturing, aerospace components, and precision medical device production requiring tight tolerances and excellent surface integrity.
