The Charmilles Robofil 440CC is a precision 5-axis submerged wire EDM machine designed for complex and accurate machining of workpieces up to 1200 x 700 x 400 mm and weighing up to 1500 kg. It features X, Y, and Z travels of 550 x 350 x 400 mm, with additional U and V axes of 550 x 350 mm, enabling taper cutting up to ±30 degrees. The machine employs a Charmilles Millennium CNC control system, providing precise path control and advanced programming capabilities. It is equipped with a Clear-Cut ("CC") generator and transformer, ensuring a stable, high-quality electrical discharge process. Automatic wire threading supports wires from 0.1 to 0.3 mm diameter, facilitating continuous operation without manual intervention. The system uses glass scales for X and Y axes with a resolution of 0.5 microns, enabling micron-level accuracy. Wire speed and tension are programmable, allowing adjustments for different materials and cutting requirements. The process is fully submerged in dielectric fluid, enhancing cutting stability and surface finish. The machine also includes anti-collision protection across all axes to safeguard both workpiece and machine components. With overall dimensions of approximately 117 x 145 x 97 inches and weighing about 7,275 lbs, the Robofil 440CC integrates essential features such as a touchscreen display, Ethernet connectivity, remote control capability, and a chiller for thermal stability, making it suitable for high-precision tool and mold manufacturing in demanding industrial applications.
