Used Charmilles CNC Machines & Tool Room Equipment for Sale

Charmilles was founded in 1954 in Geneva, Switzerland, at a time when electrical discharge machining was still an emerging industrial technology. The company quickly established itself as one of the earliest commercial EDM manufacturers, introducing innovations such as the Isopulse generator for improved spark stability and the Isocut electrode-orbiting system that redefined cavity machining. In 1996, Charmilles merged with fellow Swiss EDM leader Agie to form the Agie Charmilles Group, which later became part of GF Machining Solutions and is now operating under the United Machining Solutions umbrella.

Charmilles built its product reputation around two flagship families. The Roboform series covers CNC die-sinking (sinker) EDMs, ranging from compact shop-floor models like the Roboform 20A, 22, 23, 30, and 40 up to large-capacity machines such as the Roboform 55, 350, and 550. These sinker EDMs use a shaped electrode to erode cavities in hardened conductive workpieces with exceptional surface finish and dimensional accuracy. The Robofil series addresses wire EDM applications, with models including the Robofil 240, 290, 300, 400, 440, 510, and 690, offering submerged machining, automatic wire threading, and five-axis taper cutting capabilities.

Charmilles EDM machines serve industries where hard-material precision is non-negotiable. Tool and die makers rely on Roboform sinker EDMs to produce injection mold cavities, stamping dies, and extrusion tooling. Aerospace manufacturers use both sinker and wire EDM platforms for turbine components and structural parts in nickel superalloys and hardened steels. Medical device producers, automotive suppliers, and electronics manufacturers also depend on Charmilles equipment for tight-tolerance work that conventional cutting tools cannot achieve.

Used Charmilles EDMs attract strong buyer interest for several reasons. The machines are built to Swiss precision standards with robust castings, linear glass-scale feedback, and proprietary generators that maintain accuracy over decades of service. Consumable parts such as filters, wire guides, and power-feed contacts remain widely available through the Agie Charmilles service network and independent suppliers. The Roboform and Robofil platforms hold their value well on the secondary market because their CNC controls are well documented, operator training resources are plentiful, and the machines can be returned to factory-level performance with straightforward maintenance.
