Overview

What it is

A quarry wire saw drives a closed loop of diamond wire around a flywheel. The wire is threaded through two intersecting drill holes in the rock, and as the machine travels back along its rail it tensions the wire and pulls it through the stone, making clean, straight cuts many metres long.

It replaced explosives and the old helical sand-wire in most dimension-stone quarries because it wastes less stone and leaves sound, fracture-free blocks. Power, flywheel diameter and wire speed are matched to the stone, from lighter units for marble to high-power machines for hard granite.

Applications

Best used for

  • Primary cutsSeparating large benches from the quarry face.
  • Squaring blocksTrimming irregular blocks to saleable, square sizes on site.
  • Where blasting is restrictedQuiet, vibration-free cutting near towns or protected sites.
  • Concrete demolitionThe same principle cuts reinforced concrete.

Options

Configurations

  • Most quarries

    Electric with inverter

    Smooth speed control and lowest running cost where grid power exists.

  • Remote sites

    Diesel

    Independent of the grid; higher fuel and maintenance cost.

  • Block yards

    Compact squaring saw

    Smaller machines for trimming blocks rather than primary cuts.

  • Italian makers close for about three weeks in August; orders placed in July often slip to September.
  • Chinese makers close for Lunar New Year; order by early December for spring delivery.
  • Large lines are built to order: expect three to nine months from deposit to commissioning.
  • Plan installation for your own slow season so the changeover doesn't cost production.

Before you order

Buying checklist

  1. 1Match motor power and flywheel to your hardest stone.
  2. 2Insist on inverter (variable-speed) control and automatic wire tensioning.
  3. 3Check rail length and how easily the machine moves between benches.
  4. 4Budget wire consumption (square metres cut per metre of wire): it's the real running cost.
  5. 5Confirm spare flywheel rubbers and a local service technician.

Price level: Italian machines cost more but hold resale value; Chinese machines cut the entry price.
