Thermal Spraying Preprocessing Geometry, Thermal Spraying Preprocessing Method, And Thermal Spraying Preprocessing Device

A boring cutter body (5) is inserted into a circular hole (3) and moved in an axial direction while being rotated, thereby forming a screw-shaped trough portion (11) by a cutting tool (9) provided on an end circumferential portion of the boring cutter body (5) and also forming a broken-out section (...

Beschreibung
Zusammenfassung:	A boring cutter body (5) is inserted into a circular hole (3) and moved in an axial direction while being rotated, thereby forming a screw-shaped trough portion (11) by a cutting tool (9) provided on an end circumferential portion of the boring cutter body (5) and also forming a broken-out section (15) formed by breaking a crest portion occurring as a result of the formation of the trough portion (11). Further, electric discharge machining is performed on the trough portion (11) by means of a wire electrode (17) provided backward in the rotational direction of the boring cutter body (5) relative to the cutting tool (9), thereby forming a fine irregularity portion (41) having a finer irregular geometry than the broken-out section (15).
