Diamond Wire Saw for Granite Block Extraction

Choose the diameter from the granite and the machine, because all three share the same structure — 6 mm bead width, 40 beads per meter and rubber fixing. The 10.5 mm wire suits smaller KSSJ quarry machines and more homogeneous, medium-hard granite where the machine's power and flywheel arrangement cannot load a heavier wire efficiently. The 11.5 mm wire is the general quarry balance: enough section for hard, abrasive granite on standard KSSJ setups without overloading smaller machines. The 12 mm wire is intended for the hardest and most abrasive benches, where a larger wire section carries the load that would wear a thinner wire prematurely. In practice, send us the granite type or a sample description, the KSSJ machine model, and the typical cutting depth; we confirm the diameter against the machine's power class and your production target. If your quarry mixes stone classes across benches, it is common to standardize on the 11.5 mm wire and reserve the 12 mm wire for the hardest sections, rather than stocking all three diameters from the first order.

The rubber compound is there to hold the beads in position under heat and shock — the two conditions that end a quarry wire's life early. During a granite cut, each bead generates friction heat at the cutting face, and the wire flexes and twists as it travels around flywheels and through a kerf that is never perfectly straight. A rubber carrier with high temperature resistance stays elastic at bead-line temperatures, so beads cannot migrate or spin, and it absorbs the shock when the wire re-enters the cut after passing a pulley. This is why the wire is specified for harsh working conditions: abrasive slurry, bench debris and long cutting cycles are exactly the environment where a softer plastic carrier would soften, lose bead spacing and start wandering off the line. The same rubber carrier also damps vibration along the wire, which is the mechanism behind the low-vibration, low-noise running and the absence of dry dust at the face. None of this changes the basic physics — bead life still varies with stone abrasiveness, water supply and feed discipline — but it removes the coating itself from the list of failure causes.

This wire is the matched cutting tool for DINOSAW KSSJ quarry wire saw machines, supplied as a closed loop ready to mount. Installation follows the KSSJ manual: thread the loop around the main flywheel and the guide pulleys along the cutting line, then set tension to the machine's specified range before the first cut. Correct tension matters more with a rubber-coated wire than operators expect — too loose and the wire wanders and slaps the pulleys, too tight and the carrier is overloaded before the stone ever loads the beads. Once mounted, the cut itself is controlled from the machine's remote station, so the operator works at a distance from the face. Before production, confirm three things: that the loop length matches your KSSJ model and pulley arrangement, that water delivery reaches the bead line continuously, and that the first cut is run at a conservative feed speed so wear behavior can be checked on the actual granite. DINOSAW can coordinate wire specification, loop length and machine setup as one package so the quarry receives a working extraction combination rather than a wire that still needs engineering on site.

Send six items first, and the quotation becomes a configuration instead of a guess. One: the stone — granite type, origin or a hardness description, because stone abrasiveness is the main variable behind both diameter choice and bead life. Two: the machine — your KSSJ quarry wire saw model, or the machine you intend to pair the wire with, since loop length and diameter must match the flywheel and power class. Three: the cutting program — typical block dimensions, average cutting depth and meters of cut per week, which converts into wire consumption and order volume. Four: working conditions — water supply at the face, bench temperatures and any debris or slurry issues, because these confirm the rubber specification is the right coating class. Five: destination country, so packing, documentation and delivery terms are quoted correctly. Six: whether you need a one-off trial order or a recurring supply program, since recurring quarry programs are quoted differently from single loops. With these six items, DINOSAW can confirm diameter, loop configuration and delivery schedule in one reply — and if the application turns out to fit another wire in the family better, we say so before you order.
