How to cut granite

November 3, 2008

How to cut granite: Over the years the main method has remained the same but to perform the steps the type of machineries used has changed drastically. Science has transformed the old machines into much more effective and time saving types. Three basic machines are used in granite fabrication. These are saws, polishers and routers.

Saws
Block saw or gang saw cuts the stone blocks into slabs. Nowadays diamond wire saw is used for cutting. The machine has

a wire and on the wire a commercial diamond is fixed. Diamond itself is the hardest stone. So it makes the job much quicker. Then a bridge saw is used to give the slabs proper size. Granite is currently known only on Earth where it forms a major part of continental crust. Granite often occurs as relatively small, less than 100 kmĀ² stock masses (stocks) and in batholiths that are often associated with orogenic mountain ranges. Small dikes of granitic composition called aplites are often associated with the margins of granitic intrusions. In some locations very coarse-grained pegmatite masses occur with granite.

Granite has been intruded into the crust of the Earth during all geologic periods, although much of it is of Precambrian age. Granitic rock is widely distributed throughout the continental crust of the Earth and is the most abundant basement rock that underlies the relatively thin sedimentary veneer of the continents.
