Charmilles was founded in 1952 in Switzerland, originally specializing in electrical discharge machining (EDM) technology. The company became a leading manufacturer of wire EDM and die-sinking EDM machines, later expanding into high-speed milling systems. In 2005, Charmilles merged with Agie to form AgieCharmilles, which was subsequently acquired by GF Machining Solutions, a division of Georg Fischer AG.

The brand serves mold and die, aerospace, automotive, medical device, and electronics industries. Its main product lines include wire EDM machines (CUT series), die-sinking EDM machines (FORM series), and high-speed milling centers (HSM/Mikron series). Popular models include the CUT 200/300/400 wire EDM series, FORM 20/30/200 die-sinking machines, and HSM 400/LP high-speed milling centers. These systems are recognized for precision machining of hardened materials and complex geometries.
