PRODUCTION METHOD OF A DIAMOND WIRE AND DIAMOND WIRE FOR CUTTING STONE-LIKE MATERIAL

摘要

A production method of a diamond wire (1) for cutting stone-like material comprising the steps of: threading a predetermined number of abrasive beads (3) on the supporting cable (2); joining the two ends (2a) of the supporting cable (2) by appropriately interweaving the strands (6) of the supporting cable (2), so as to form a closed loop; distributing the diamond beads (3) on the supporting cable (2) so that the discontinuity points (P) of the supporting cable (2) are arranged along as many uncovered longitudinal stretches (5) of the supporting cable (2) spaced from two abrasive beads (3) delimiting the same uncovered longitudinal stretch (5); and injection moulding the outer tubular sheath (4) made of plastic material directly over the supporting cable (2) so as to cover the supporting cable (2) and also form, at least along the uncovered longitudinal stretches (5) accommodating the discontinuity point (P) of the supporting cable (2), as many enlarged sheath segments (10) each extending astride the discontinuity point (P) and being spaced/distanced from the two abrasive beads (3) located at two ends of the same uncovered longitudinal stretch (5).
