CONCORD DK7720 VC WIRE EDM MACHINES

Technical Description

The CONCORD DK7720 VC Wire EDM Machine is a CNC-controlled electrical discharge machine designed for precision wire cutting with travel capacities of 7.87 inches on the X-axis, 9.84 inches on the Y-axis, and 11.81 inches on the Z-axis. It features a working table size of approximately 200mm by 250mm, supporting workpieces up to 100kg. The machine boasts a high cutting accuracy of around 0.015mm to 0.02mm and a surface finish quality of 2.0 - 2.5 μm roughness. It operates using molybdenum wire with diameters typically between 0.13mm and 0.20mm, achieving cutting speeds up to 100-180 mm²/min depending on conditions. The DK7720 VC runs on a 1.2 - 1.5 kW power supply with voltages customizable from 220V single-phase to 380V three-phase and a 50/60 Hz frequency. Its CNC control system includes AutoCut software, supporting programming via AutoCAD integration and a 15" TFT LCD display on a Windows XP/7 platform. Key features include digital linear scales for precise positioning, high-pressure water pumps for flushing, auto wire tension, and an ergonomic handle controller for ease of use. The machine weighs about 800kg and incorporates advanced functions such as auto stop at wire breakage, auto edge and center finding, and options for single or multicut operations. It is suitable for processing complex 2D and 3D mold components, punch dies, and specialty materials in industries like electronics, precision tools, and automotive manufacturing. Packaging is typically in a wooden case for protection during transport.
