Title: Wire electrode for wire cut electric discharge machining
Inventor: MIZUNO SHIGERU
IPC: B23H7/08
Filed: 1986-05-19
Abstract: PURPOSE:To increase the modulus of elasticity of an electrode wire, to increase tensile strength, and to enable change of physical properties of the discharge surface of a wire, by a method wherein a wire electrode is formed by a core, formed such that a number of carbon fibres, with which a metal is covered, are bundles to apply heating compression thereon, and a conductive member, the surface of which is covered with a conductive material. CONSTITUTION:Since carbon fibre 2 having high elasticity and high yield strength is used in a central part as a conductive strength member for a core 4, the core 4 is capable of providing tension further higher than that of a conductive member 3 with which the surface of the core is covered. Through the conductive member 3 on the surface of the core bears the subject of electrical conduction, since a short pulselike current is caused to flow through an electrode wire, most of the current flows over the surfaces of the electrode wire. Thereby, the intensity of apparent electric resistance of the wire is neglected, and in phenomenon of adhesion to an object to be machined due to the electric discharge machining, an adhesion amount can be decreased because an alloy of tin and the like is usuable as a conductive material. Further, since the carbon fibre is covered with a metal 1, drape with a conductive member is excellent.
