The JZ DK77100 Wire EDM Machine is a high-precision CNC wire electrical discharge machining tool designed for cutting complex 2D and 3D components with a maximum X-axis travel of 39.37 inches (1000 mm), Y-axis travel of 47.24 inches (1200 mm), and Z-axis travel of 23.62 inches (600 mm). It supports wire diameters ranging from 0.12 to 0.20 mm, typically utilizing molybdenum wire, and achieves cutting speeds up to approximately 300 mm²/min with a cutting accuracy of ±0.015 mm and surface roughness as low as Ra 1.4-2.5 μm, depending on the cutting conditions. The machine is configured with a water-submerged cutting area to enhance cooling and debris removal, with a water tank capacity around 60-100 liters. Although it lacks auto threading capability, it offers manual Z-axis adjustment and is equipped with a robust CNC controller system compatible with Windows-based software such as AutoCut and AutoCAD for programming and operation. The unit supports taper cutting up to ±6° over 80 mm thickness with optional extensions to ±15° or ±30°. The machine’s stable construction ensures a maximum workpiece cutting thickness up to 800-1000 mm and can bear table loads up to 2600-3000 kg. Its power requirements include 220-415V three-phase supply with typical power consumption of around 3 kVA. The JZ DK77100 is suited for high-precision applications in tool and mold making, electronics, and light industry sectors, capable of machining intricate shapes in diverse conductive materials with fine control over discharge conditions for optimal surface finish and dimensional accuracy.
