摘要:
cBN powder (11) which is an electrically insulating hard matter is mixed with Co-based alloy powder (12) which is a conductive matter, resultant powder mixture is put into a press mold and compression-molded to thereby form an electrode for discharge surface treatment (10). Electric discharge is generated between the electrode (10) and a treatment target material (16) by a discharge surface treatment power-supply unit (17), and a hard coat (20) made of cBN and Co-based alloy having high hardness even in a high temperature environment is formed on the treatment target material (16).

An electric discharge is generated between an electric discharge surface treatment electrode and a wire electrode, and an electric discharge surface treatment material is stuck on the surface of the wire electrode by the energy of the electric discharge. An electric discharge is then generated between a work piece and the wire electrode on which the electric discharge surface treatment material is stuck, and a surface modified layer is formed on the surface of the work piece by the energy of the electric discharge.

A wire electrical discharge machine includes a wire electrode for causing electrical discharge to take place between the wire electrode and a workpiece; a first roller and a second roller for feeding the wire electrode while nipping the wire electrode; wire conveyor for inserting the wire electrode into a portion between the first roller and the second roller by causing a fluid to flow to opposing portions of the first roller and the second roller; and driver for moving a distal end of the wire conveyor to a vicinity of the opposing portions, and for moving the distal end of the wire conveyor away from the opposing portions a predetermined distance upon completion of the insertion of the wire electrode into the nip between the first roller and the second roller.
摘要:
In a wire guide device for a wire electrodischarge machine, a holder member has at least an insertion path permitting insertion of wire electrode and a wire guide forming part of the insertion path. A housing holds the holder member and a guide holding sleeve is provided at the holder engaging part of the housing and resiliently holds the holder member by a device for a working fluid. A groove provided between the guide holding sleeve and the holder engagement part and forms a closed path for sealing the working fluid, and a pressure regulating device provided in the housing communicates with the groove. A positioning device positions the holder member with respect to the housing, around the electrode. A stylus shaped cleaning member (element 75) is used to remove chips deposited near the inner end of tapered cooling apertures to eliminate clogging.
