Electroplated & Vacuum Brazed Diamond Wire Saw for Marble Quarrying

This family is built for sharp, dry-capable cutting in marble quarrying and multi-material scenarios — it is not the default answer for every wire saw job. Three situations call for a different DINOSAW wire. First, hard-stone quarry duty: if you cut granite or similarly hard, abrasive rock in long production campaigns, the rubber-coated sintered wire family is the quarry standard, with a bond designed for sustained wear rather than maximum sharpness. Second, marble block squaring: for squaring and shaping already-extracted blocks, the plastic-fixed marble squaring wire is the purpose-built option, with the assembly matched to that duty. Third, demolition and reinforced concrete: cutting concrete, steel-reinforced structures or demolition work belongs to the RC demolition wire family, whose bead specification and fixing are designed for that material. Stay with this electroplated and vacuum brazed family when the priority is sharp response, high cutting efficiency, and the ability to cut wet or dry across marble and mixed building materials. If you are unsure, send the stone name, photos of the material and the machine model, and the application will be matched to the right wire family before quoting.

Yes — the vacuum brazed wires are specified for wet and dry cutting, and dry capability is one of the main reasons quarries choose this family. In dry cutting there is no water to cool the beads and flush the kerf, so two things matter more: sharpness, because a sharp bead generates less heat per meter cut, and bead spacing, because open spacing clears dust from the kerf instead of packing it against the wire. This is why the brazed range offers several beads-per-meter options — 28, 34, 40 and 60 — so the wire can be matched to the stone and to dry or wet operation rather than forcing one density on every job. Practical dry-cutting practice: keep machine parameters conservative on the first cuts of a new stone, inspect bead condition at regular intervals, and select the fixing assembly from the catalog data — 9 mm spring, 10.5/11 mm plastic, 11.5 mm rubber + spring — according to the machine. Dry cutting also removes water supply and slurry management from the site plan, which changes the economics of remote benches and building-material jobs where water is difficult to arrange.

Three sets of numbers decide how the wire behaves in the cut. Diameter — 9, 10.5, 11 and 11.5 mm for the brazed range, 10.1 mm for electroplated — must match your machine's pulley groove and the cutting load; the wrong diameter accelerates bead and pulley wear. Bead width — 7.2, 8.8, 9.8 and 10.8 mm on the brazed family, 9.8 mm on the electroplated wire — sets the kerf width and the support each bead gets in the cut: wider beads track more stably, narrower beads reduce kerf loss in valuable stone. Beads per meter — 28, 34, 40 and 60 on the brazed range, 40 on the electroplated wire — sets how aggressively the wire engages: higher density spreads the load across more cutting points, lower density opens the kerf for slurry and dust clearance, especially in dry cutting. None of these numbers should be chosen in isolation. The selection logic is stone first, machine second: name the stone and its condition, confirm the machine and pulley setup, then fix diameter, fixing style, bead width and beads per meter together. That combined answer is what DINOSAW needs to quote the correct specification.

Send four groups of data and the quotation comes back as a wire specification rather than a guess. Machine data: the wire saw model, main wheel diameter and the pulley or guide wheel setup — these fix which diameters and fixing styles your machine can run, from the 9 mm spring assembly up to the 11.5 mm rubber + spring wire. Stone data: the stone name or a photo, its hardness and abrasiveness as you know them, and whether the job is marble quarrying or mixed stone and building materials — this selects brazed versus electroplated and the bead width. Cutting data: wet or dry operation, average and maximum cut length, and the production target per shift — this decides beads per meter within the 28–60 range. Site data: water availability, power conditions and the destination country, which affect fixing-style recommendations, packaging and delivery. With these, DINOSAW confirms diameter, bead fixing, bead width and beads per meter, checks availability of the exact construction, and quotes wire length, price and delivery. If any item is unknown, send what you have — machine model and stone name alone are enough to start the selection.
