DEVICE, LINE AND METHOD FOR MANUFACTURING TUBULAR SUPPORTS FOR THE DIAMOND BEADS OF A CUTTING WIRE FOR STONE MATERIAL, AND TUBULAR SUPPORT AND CUTTING WIRE FOR STONE MATERIAL INCLUDING SAID SUPPORT

摘要

A method for manufacturing tubular supports (4) designed to support respective diamond outer members (3) to manufacture diamond beads (5) susceptible to be coupled to the flexible support structure (2) for manufacturing a wire (1) for cutting into slabs blocks of stone material. The method comprises the following steps: i) providing at least one metal tubular semifinished support (4') including two opposite ends (100', 100") to be finished; ii) finishing of the at least one metal tubular semifinished support (4') to obtain a finished tubular support (4). The finishing step ii) includes a step ii') of internal countersinking of the opposite ends (100', 100") of said at least one metal tubular semifinished support (4').
