Influencing Factors Of Diamond Tools Processing Stone Products

The main factors that affect the stone processing The processing of stone is mainly sawing, cutting, grinding and polishing. The machinability of stone refers to the ease of sawing, cutting, grinding and polishing. Saw, cut the same, grinding, throwing although there are differences, but very similar. Therefore, the general processing of stone usually refers to sawability and grindability. The main factors that affect the processability of stone are:

(1) Hardness

In normal circumstances, the greater the hardness of the stone, the more difficult processing, the greater the wear on the tool.

     (2) mineral composition and chemical composition

Stone material composition Material composition, including mineral composition and chemical composition, different mineral composition and chemical composition, processibility is also different. Such as marble rock mineral mainly calcite, dolomite, Mohs hardness is 3 and 3.5-4, compared with granite hardness is low, easy to process. The main granite rock-forming minerals are quartz, orthoclase, plagioclase, their Mohs hardness of 6.5-7. Its workability depends largely on the quartz and feldspar content, the higher the content, the more difficult processing. In chemical composition, such as sio2 content is higher, the more difficult processing.

    (3) the structure of the rock

In general, the uniform grain than non-uniform stone easy processing, fine grain polished than the high quality, dense stone than the loose stone high gloss. Mineral crystallinity is good, and the orientation, the same direction of the optical axis will greatly improve the gloss after polishing. Rock cleavage, grain boundaries and initial cracking are also important factors affecting workability.

    In addition, the choice of tooling and process parameters is a factor that must be considered.

    Decorative finishes used in building decoration mainly marble and granite two categories. The decorative stone blocks processed into architectural decorative plates, the main process of sawing, grinding and polishing, cutting the finished plate, trimming chamfering groove. Saw cutting manufacturing process which is the most critical, it determines the product yield and quality. In the sawing process with a diamond saw blade used up. According to statistics from home and abroad, it is estimated that about 50% of the industrial diamonds in the world are used to manufacture stone processing tools, of which the main ones are stone processing saw blades.
