The CHMER RX853F Wire EDM Machine is a high-precision CNC-controlled wire-cut electrical discharge machining system designed for demanding industrial applications. Featuring a robust construction, it offers X-axis travel of 31.5 inches (800 mm), Y-axis travel of 19.7 inches (500 mm), and Z-axis travel of 11.8 inches (300 mm), enabling the machining of large and complex workpieces. The machine supports a maximum workpiece size of 1210 x 800 x 295 mm and can handle workpieces weighing up to 2000 kg (4409 lbs), making it suitable for heavy-duty operations. Its advanced AC servo motor axis drive system ensures accurate and reliable movement, while the wire diameter range of φ0.15–0.3 mm (standard φ0.25 mm) and a maximum wire feed rate of 300 mm/sec provide flexibility and efficiency in cutting operations. The RX853F is equipped with a taper cutting capability of ±21°, facilitated by a wide-angled nozzle and DA+DB=15 mm configuration, allowing for intricate angled cuts. Additional features include an auto data recovery system after power outages, dual water chillers for both flushing and submerged operations, and optional accessories such as auto wire threading, auto wire chopper, and a 2-in-1 transformer with AVR. The machine’s outside dimensions are 2400 x 2800 x 2350 mm, and it weighs approximately 5460 kg (12,000 lbs), reflecting its sturdy build and industrial-grade durability. Designed for both flushing and submerged cutting modes, the RX853F delivers consistent performance, precision, and reliability in a wide range of EDM applications.
