The process of cutting large block into slabs or tile is very imperative and arduous phase to get finish marble. Marble is softer than granite. But it is one of the hardest stone. The tools (blade, saw and cutter) are used for marble cutting, must be consists of diamond due to high hardness of marble. Cutter disk, diamond gang saw are main machines that used for marble cutting. The components cutting machinery are must have long life feature owing to marble hardness.
The operation of cutting the large blocks into large slabs and small tiles cutting is very crucial phase of finish marble processing.
Cutting Processing : Dressing of blocks: In the mining process block are extractions from quarry with the help of gang saw and some other tools. Then these blocks are sent for dressing. In dressing processing unit, these blocks are cuts into almost finish block shape. Diamond Gang saw machine: Diamond saw blades are best for marble cutting. The diamond blades tool can be attached to disc grinders. In the processing unit, blocks get cut down into smaller pieces. After dressing the blocks, blocks are processed in gang saw diamond. A gang saw works as piece slicer. It has many adjustable blades consist of segments. The blades permit the adjustment according to slab thickness. The multi blade gang saw is new cutting machine with latest technology.
The Gang saw cuts the block with support of water. Water is mandatory in marble cutting.
Marble is hard stone after granite. There are three types of marble hardness: 1. High hard 2. Medium hard 3. Soft marble According to hardness marbles cutting takes time. As much marble is hard, cutting will consume more time.
The tools are used for marble cutting must be sharp cutting edge and accurate cutter because cutting is base of polishing phase and finishing.
