Granite Block cutting

The first step of the process is a primary cutting or shaping of the material.

This is typically accomplished for granite using a diamond wire-saw.

When operating a circular or diamond wire saw, a continuous tream of

water over the saw is required in order to dissipate heat generated by the process;

sufficiently-elevated temperature can cause major machine and material damage.

Gang-saw​

Once the block has been shaped from the wire-saw, matting is done to ensure that

there are no cracks or breakage during the cutting process. The blades are set in

the gang-saw machine according to the hardness of the rock and the

thickness specification for cutting, and accounting for the loss of thickness

in cutting and further processing. The granite block is loaded onto the tray and

packed with cement and left to dry for a day to ensure, there is no movement

while the cutting process.

The tray housing the granite block is then moved into the gang-saw machine. A mixture of water, lime, and grit; referred to as the slurry is used in the cutting process that helps in gutting the block as absorb any heat dissipating from the cutting process. The viscosity of the slurry is vehemently monitored and adjusted for every material and also during the cutting process.

Every 2-3 hours the machine and the block is observed and re-adjusted, if needed to ensure a steady and straight cut for the blocks. Once the slabs are cut, they are inspected for any defects and then are marked individually for inventory tracking and moved for further processing.

Cutter

Once the block has been shaped, it is then moved to the cutter machine. The width of the blades are adjusted as per specification. There are wide range of cutter machines from single blades, all the way to 10 blades in one machine. The more the number of blade, the faster the cutting process for a block. However, single blade cutter machines are used to process blocks as per non standard size / thickness.

During the cutting process, a stream of distilled water is also sprayed to absorb any heat dissipating from the cutting process and minimize any sparks. The blocks are cut until the last few inches are left and then a team of stone specialists, cut and extract the slabs from the cut block, one-by-one. These slabs are then inspected thoroughly for any defects, and then numbered for inventory tracking and moved for further processing.
