Electro – Discharge Machine

MOD. 4K7722AF1

Made by Kauno Stakles
Electro-discharge jig-copying-broaching machine of very high coordinates reading accuracy, with numerical and adaptive control, is designed for machining thought and blind holes of any configuration indies, metal molds and compression molds made of any electrically conductive materials, hardened steel, and hard alloys included, by a method of electro-discharge copying-broaching. Machining is possible with a fixed electrode as well as with an orbitally moving or a rotating electrode-tool along X and Y axes. The pump unit for supplying the machine table bath with dielectric liquid is equipped with replaceable filters (filtering fineness 0.01 mm) and a temperature control device.
