CHARMILLES ROBOFIL 240 WIRE EDM MACHINES

Technical Description

The Charmilles Robofil 240 is a CNC wire EDM machine designed for high-precision electrical discharge machining with a submerged cutting method. It features a work envelope with X-axis travel of 13.75 inches, Y-axis and Z-axis travel both at 8.66 inches, suitable for machining complex parts up to 13.75" x 8.66" x 8.66". This model includes automatic wire threading and rethreading capabilities to enhance operational efficiency and reduce downtime. The machine operates under Charmilles Millennium CNC control, enabling precise contouring and multi-axis machining. The wire EDM cutting process takes place submerged in a dielectric fluid bath, improving cut quality and thermal management. The system incorporates a CleanCut generator technology and optical scales for superior cutting speed, accuracy, and anti-collision protection. It can handle workpieces weighing up to approximately 750 kg with maximum taper cutting angles of ±30° up to 220 mm in height, with an optional module extending taper capabilities to ±45°. The machine construction uses a polymer concrete base for vibration damping, contributing to the high precision of the cuts. It supports wire diameters typically from 0.004" to 0.012", and its dielectric tank has a large capacity for efficient flushing. Overall, the Robofil 240 is suited for manufacturing precise and intricate components in aerospace, medical, and tooling industries requiring complex shapes and tight tolerances. It balances robust cutting power with advanced automation features, ensuring both accuracy and productivity in wire EDM operations.
