production method of a diamond wire and diamond wire to cut rock-like material

摘要

a method of producing a diamond wire (1) for cutting rock-like material comprising the steps of: threading a predetermined number of abrasive beads (3) on the support cable (2); join the two ends (2a) of the support cable (2) by appropriately interweaving the filaments (6) of the support cable (2), so as to form a closed circuit; distribute the diamond beads (3) on the support cable (2) so that the discontinuity points (p) of the support cable (2) are arranged along many uncovered longitudinal stretches (5) of the support cable (2 ) spaced from two abrasive beads (3) that delimit the same longitudinal stretch discovered (5); and injection mold the external tubular sheath (4) produced of plastic material directly on the support cable (2) in order to cover the support cable (2) and also to form, at least along the uncovered longitudinal stretches (5 ) that accommodate the discontinuity point (p) of the support cable (2), many increased casing segments (10) each extending along the discontinuity point (p) and spaced / spaced from the two abrasive beads (3) located at two ends of the same uncovered longitudinal stretch (5).
