Method of and arrangement for preventing uncontrolled oscillations of electrode wire in electroerosion machining apparatus

摘要

Uncontrolled transverse mechanical oscillations of an electrode wire in the traveling-wire electroerosion machining apparatus are effectively and efficiently prevented by provision of a novel assembly comprising a mass of magnetic fluid retained in a pair of magnetic pole pieces and disposed in a straight line path defined between a pair of machining wire guide and support members to accommodate the traveling electrode wire. A magnetic field is established between the pole pieces to actuate the magnetic fluid, thereby damping uncontrolled oscillations as caused in the traveling electrode wire.
