APPARATUS AND METHOD FOR MACHINING CYLINDRICAL GROOVES BY MULTI-WIRE CUTTING OF PROFILES

Provided are an apparatus and a method for machining cylindrical grooves by multi-wire cutting of profiles, the apparatus includes a driving guide roller and a driven guide roller in a guide roller assembly with axes thereof disposed parallelly and symmetrically, a tension wheel further disposed between the driving guide roller and the driven guide roller, a cutting wire clamped in grooves of the driving guide roller and the driven guide roller and perpendicular to a central axis of a workpiece, and a plurality of segments of the cutting wire forming a cutting wire group mesh surface; and a plurality of grooves are machined simultaneously on the cylindrical surface of the workpiece by the wire group mesh surface, and the cutting wire forms a machining pressure under an action of tension wheel, which can feed smoothly and ensure the accuracy and machining efficiency of the grooves.
