CHMER A422S WIRE EDM MACHINES

Technical Description

The CHMER A422S is a compact all-in-one wire electrical discharge machining (EDM) system featuring a FANUC-based CNC control platform. This machine delivers exceptional precision machining capabilities with X, Y, and Z axis travel of 15.75 inches, 9.84 inches, and 8.66 inches respectively. The system accommodates maximum workpiece dimensions of 31.5" × 22.0" × 8.5" with a maximum workpiece weight capacity of 550 pounds. The A422S operates as a fully submerged wire EDM machine, enabling superior precision during complex cutting operations. It features 5-axis control (X, Y, Z, U, V) with a minimum setting unit of 0.001mm and supports both linear and circular interpolation for intricate part geometries. The machine utilizes an AC servo motor drive system with a maximum XY feed rate of 31.5 inches per minute and accommodates wire diameters ranging from 0.006" to 0.012". Advanced features include automatic wire threading, a digital water conductivity controller, and a dielectric filtration system for consistent cutting performance. The control system incorporates a 15-inch color display, 32-bit single CPU architecture with semi-closed loop capability, and data input options via keyboard, RS-232C, USB, and LAN connectivity. The machine operates at 3-phase 220V±10%, consuming 13KVA of power. With its advanced compact design achieving approximately 25% space savings compared to conventional models, the CHMER A422S represents an economical high-performance solution for precision wire EDM applications.
