Technical Description
The CHMER A422SL is a high-precision, 5-axis CNC wire EDM machine engineered for advanced cutting applications. Featuring an X-axis travel of 15.75 inches, Y-axis travel of 9.84 inches, and Z-axis travel of 7.87 inches, this model delivers robust work envelope capabilities for intricate part machining. The machine supports submerged cutting, enhancing accuracy and surface finish by maintaining a stable dielectric fluid environment throughout the process. Its CNC control system offers intelligent programming, precise axis management, and seamless integration with modern manufacturing workflows. The A422SL utilizes a combination of linear motors on the X and Y axes and AC servo motors on the U, V, and Z axes, ensuring rapid, smooth, and accurate movement for complex geometries. With a maximum workpiece weight capacity of 550 kg (1,212.5 lbs) and a machine weight of approximately 5,732.2 lbs, it provides exceptional stability during operation. The wire diameter range is 0.15–0.3 mm, supporting fine to standard cutting needs, while the maximum wire feed rate reaches 300 mm/sec and wire tension is adjustable from 300–2,500 gf for optimal cutting performance. The taper angle capability is ±14.5 degrees per 80 mm, enabling precise angled cuts. The working fluid supply system includes a 580L tank, automatic conductivity and temperature control, and paper filtration with ion exchange resins for consistent fluid quality. The machine’s control features a 15-inch color display, 32-bit single CPU, and support for linear and circular interpolation, with a setting unit of 0.001 mm for micron-level accuracy. Designed for reliability, efficiency, and ease of use, the CHMER A422SL is ideal for demanding EDM environments.
