Diamond tools for processing stone products, the impact of the main reasons

Stone processing mainly sawing, cutting , grinding, polishing . Means workability stone sawing, cutting , grinding, polishing and ease of processing .
Sawing, cutting the same , grinding, polishing , although different, but very similar. So the general workability dry core drill bits  usually refers to the stone can be cut and grindability . Affect the stone processing are the main factors :
( A ) Hardness
Generally , the greater the hardness of the stone , the more difficult the process , the greater the wear of the tool .
( 2 ) Mineral and chemical composition
The material components stone material components include mineral composition and chemical composition , different minerals and chemical composition , processing is different. Such as marble rock-forming minerals are calcite , dolomite , and its Mohs hardness is 3 and 3.5-4 , respectively , compared with granite low hardness, ease of processing . Granite is glass blades  the main rock-forming minerals quartz, orthoclase , plagioclase , and their Mohs hardness of 6.5-7 . Its workability depends largely on the content of quartz and feldspar , the higher the content , the granite blades  more difficult process . In the chemical composition , such as the higher SiO2 content , processing more difficult .
( 3 ) the structure of the rock structure
In general , uniform particles than the uneven stone easy processing , high quality polishing ratio tabular fine , dense stone gloss than the loose stone . Mineral good crystallinity and orientation , the optical axis direction will greatly enhance the gloss after polishing . Rock cleavage, grain boundary and initial crack on the workability is also very important factors.
