The KINGRED KD400CL Wire EDM machine is a CNC-controlled wire cutting electric discharge machine featuring precise travel ranges of 12.6 inches (320 mm) in the X-axis, 15.7 inches (400 mm) in the Y-axis, and 11.8 inches (300 mm) in the Z-axis, suitable for machining various conductive materials including steel, alloys, copper, and titanium alloys. It incorporates servo motor drives for the X and Y axes, enhancing positional accuracy through closed-loop feedback and compensation, critical for multi-hole parts and high-precision mold manufacturing. The machine’s distinctive “C” structure column supports a vertically oriented machine head and wire frame, which eliminates wire swing issues common in older “F” structure designs, ensuring stable wire feeding and cutting. The working table measures approximately 17.1 by 25.6 inches (435×650 mm), capable of supporting up to 400 kg payload. The KD400CL offers high-precision cutting with accuracy around ±0.005 mm for straight cuts and ±0.015 mm for tapered cuts, achieving surface finishes with roughness values as low as Ra ≤ 0.8 μm. It supports wire diameters from 0.10 to 0.25 mm, with automatic CNC wire feeding and tightening. The system operates on a 3 kW power supply at 380V/50Hz and weighs about 2600 kg. Additional features include multi-stage high-pressure filtration for dielectric fluid and stability-enhancing CNC controls with absolute and relative coordinate monitoring displayed on the control software, making it efficient for complex manufacturing environments and mold-making applications.
