Cutting natural stones

It is called cutting natural stone, in the specialized vocabulary, debiting. To perform this operation is used, depending on the nature of the debits, angle grinders or specific equipment. The processing possibilities of these objects are limited depending on the hardness of the material and the depth of the cut.. Saws are used for cutting, diamond wires and diamond discs.

Two cutting methods are used to process natural stone: dry cutting and wet cutting. There are specific disks for each method, marked accordingly, therefore they can only be used in the recommended range. Cutting machines mainly use wet cutting, while hand tools apply dry cutting. Cutting machines use large diameter diamond discs, from 350mm to 1000mm. For this reason, cutting machines can be used in natural stone processing plants, and hand-held machines can be used in manufacturing mode, special processing, or site adjustments.

Universal discs are not used in professional processing, but discs specific to the type of material to be cut, respectively borders, marbles, travertine, etc. Depending on the hardness of each stone, discs with a certain type of diamond coating are used.. After a certain time of use, diamond discs can be recovered by passing them through a high hardness material. Often, diamond particles stick due to overheating. Cleaning the disc has the effect of releasing used diamonds, too fine, and releasing new diamond particles from the diamond coating.

Professional serial, debit, is made with the help of cutting machines specially built for this purpose. Water is used to cool the contact area of ​​diamond disks with natural stone. The main advantage of using mechanized cutting is the working speed, effectiveness and efficiency of the operation, as well as the quality level obtained. These results are guaranteed by the working method, respectively by the stability of the cutting assembly fixed on a movable bridge. The advantage of mechanized cutting also consists in the multitude of secondary operations that can be performed, respectively calibrated flows, cutting at variable angles, execution of the joining channels in the edge of the parts.

The cutting depth is adjusted automatically, so that finished parts can be cut to a minimum accepted thickness (7mm), to extreme thicknesses (20-30cm).
