The CHMER G53S Wire EDM Machine is a high-precision CNC wire electrical discharge machine designed for submerged cutting applications. It features a robust work envelope with X, Y, and Z-axis travels of approximately 500 mm (19.69 inches), 300 mm (11.81 inches), and 215–220 mm (8.46 inches), respectively, allowing for machining of medium-sized workpieces with high accuracy. The machine incorporates advanced AC servo motors, linear guideways, and precision ball screws on multiple axes (X, Y, U, V) to ensure precise taper cutting and exceptional positioning accuracy. Its submerged cutting design reduces heat and debris, improving the quality of cuts and prolonging wire life. The machine supports wire diameters ranging from 0.15 to 0.3 mm and features a maximum wire feed rate of 300 mm/sec, with variable wire tension settings between 300 and 2500 gf to optimize cutting performance. The maximum taper angle capability is ±14.5°, enabling complex angled cuts. The G53S accommodates workpieces up to approximately 825×600×215 mm and weights up to 400–450 kg. Its structural design includes a stainless steel worktable and work tank for durability and minimal maintenance. With a maximum XY feed rate of 800 mm/min and a CNC controller for automation and process control, the G53S is suitable for high-precision and efficient EDM operations in tool making and complex part manufacturing. The machine balances flexibility, reliability, and productivity, making it an ideal solution for advanced EDM workshops requiring submerged wire-cut processing. Its compact footprint and weight (around 2900–3200 kg) reflect its robust build for industrial environments.
