CHARMILLES FI 440 CC EDM Machines

CHARMILLES FI 440 CC wire EDM was manufactured in 2007 in Switzerland by Charmilles Technologies SA. The offered machine is an excellent choice for the production of precision dies, cutting dies and punches. It enables the efficient machining of workpieces made from even the hardest materials by means of electrical discharge machining. During machining, material is removed through controlled electrical discharges occurring between the wire and the workpiece submerged in a dielectric. This results in a high-quality surface finish without the need for additional finishing operations, such as polishing.

The CHARMILLES FI 440 CC performs machining with a 5-axis cutting head. All axes of the machine are equipped with measuring systems in the form of linear scales and an anti-collision system. This solution guarantees the highest positioning accuracy and safe operation, even at high movement dynamics. The process parameters are programmed in an intuitive CNC control system offering access to a wide range of advanced functions. All this is complemented by a rigid design that maintains high stability during intensive use. The CHARMILLES FI 440 CC wire EDM weighs 2850 kg.
