Quarring process

1 The first stage consists in cutting the mountainside horizontally. A special chain saw is used to perform this task. This is an innovative machine, similar to a large electric saw, travelling on two rails. It has a 3.5 metre blade fitted with diamond or Widia segments, which cut the stone like a knife.


2 The second stage consists in cutting the mountainside vertically. The diamond wire saw is used to cut the block free from the mountain. This machine is made up of a trolley travelling on two rails, an electric motor and a lateral pulley fitted with a diamond saw. The diamond wire is passed through access drill holes and over the pulley.


3 The third stage is the squaring of the blocks: after the block has been turned over it is divided into parts with the diamond wire saw.
