Brazing diamond wire saw for cutting rare materials

The utility model relates to a brazing diamond wire saw for cutting rare materials, and relates to the field of cutting equipment. The wire saw comprises a steel wire rope and a plurality of diamond string beads fixedly arranged on the steel wire rope in a sleeving mode. Each diamond string bead comprises a cylindrical base body, a material cover arranged on the outer wall of the base body in a covering mode and a plurality of diamond particles evenly and fixedly arranged on the outer surface of the material cover. The diamond particles are 40-60-mesh sawing-grade diamonds, and the inner diameter of the cross section of the base body is 3-5 mm; the thickness of the pipe wall of the base body ranges from 0.2 mm to 0.6 mm. The wire saw has the effects of reducing the diameter of the cross section of the wire saw and improving the cutting efficiency. 本申请涉及一种名贵材料切割用钎焊金刚石绳锯，涉及切割设备领域。绳锯包括钢丝绳、多个套设固定在钢丝绳上的金刚石串珠，所述金刚石串珠包括呈圆筒状的基体、覆设在基体外壁上的料皮和多个均匀固设在料皮外表面的金刚石颗粒；所述金刚石颗粒为40~60目的锯切级金刚石，所述基体横截面的内径在3~5mm之间；所述基体的管壁厚度在0.2~0.6m
