Wire EDM is a machining method in which the material is not mechanically loaded. The part to be machined is placed in the machine in a liquid dielectric. The workpiece takes on the role of an electrode and in the dielectric there is also a very precisely tensioned wire that forms the other electrode. An electric current is carried between the electrodes. The short circuit creates sparks on the surfaces of the electrodes, which are immediately dissipated as microscopic chips by the dielectric. Our Agie Charmilles CUT 200SP wire EDM machine is characterized by a backlash-free wire guide and extremely high surface accuracy on the cutting surfaces.
