Three major factors affecting stone processing

The processability of stone material is to point to saw commonly, cut, grind, throw the difficulty of processing degree.Saw and cut the same, grinding and throwing a little difference or close, so most of the stone products of the workability is usually refers to the sawability with grinding.But what are the factors that affect stone processing in daily life?

The hardness that is stone material above all

Normally, the hardness of a stone is larger, the more difficult it is to process, the requirements of molding technology is very high, and the degree of wear and tear of processing tools is relatively larger.In the case of enhanced hardness of stone, product abrasion resistance will be enhanced together, so the cutting resistance will continue to increase, so the requirements of processing tools are more and more high.

It is the composition of stone material next

We all know the formation composition of stone includes mineral and chemical two kinds, different mineral composition and chemical composition, processing performance is also different.For example, marble, the main mineral composition has calcite, dolomite, its Mohs hardness is 3 and 3.5-4 respectively, lower than granite hardness, easy to process.And the main mineral of granite is quartz, orthoclase, plagioclase, their Moshi hardness is 6.5-7.The machinability depends largely on the content of quartz and feldspar, and the higher the content, the more difficult it is to process.In terms of chemical composition, the higher the SiO2 content, the more difficult it is to process.

And finally, the interior of the rock

In general, the structure of the stone those particles are more easy to process than the uneven;The quality of fine grain is higher than that of flake.High density of stone than loose stone looks much higher gloss;The degree of mineral crystallization is good, but also can be oriented, the same direction of the optical axis will greatly improve the gloss after polishing.
