WIPO Patent Application WO/2023/169515
Kind Code:
A1
Abstract:
A diamond wire saw with a prolonged service life, the diamond wire saw comprising a wire (30), a plurality of beads strung on the wire (30), and a covering layer (40) provided on an outer surface of the wire (30) to fix the beads. Each bead comprises a base (10) and a diamond substrate (20), wherein the base (10) is a hollow tubular body; and the diamond substrate (20) is arranged on an outer surface of the tubular body, and the diamond substrate (20) is of a structure with a narrow exterior and a wide interior. In this way, the diameter of the diamond substrate (20) is gradually reduced as cutting time elapses, but the axial dimension thereof becomes larger, such that the overall pressure of the diamond of the beads on a stone, that is, the sharpness, is effectively maintained, thus prolonging the service life of the beads.
