Selection of abrasives and grinding tools in stone curing process

with the development of economy, more and more widely used in stone's, especially all kinds of public places, stone, with its elegant gesture, loved by people, the use of it, with the change of time, can appear the problems, such as aging and contaminated preliminary solution, this can be achieved by cleaning way but sometimes must be achieved by grinding

Abrasive and grinding tools

Abrasive is used to grind processing materials, general classification is ordinary abrasive, super hard abrasive two kinds;Ordinary abrasive mainly includes corundum (brown corundum, white corundum, etc.), silicon carbide (black silicon carbide, green silicon carbide), hardness order we can sort out the granite processing is green silicon carbide, black silicon carbide, marble processing is white corundum (soft), black, green silicon carbide (hard);According to the cost of materials, green silicon carbide, black silicon carbide, and white corundum are in the order. These abrasives can be made into inorganic grinding tools, including diamond, ceramic, etc. Organic grinding tools, including phenolics, unsaturated resins, and epoxies (here also including abrasive cloth and sandpaper), make up the grinding tools of ordinary abrasive.

Diamond abrasive is a super hard abrasive. Hardness is the highest, when processing materials is the micro cutting mechanism, so it is the preferred cutting tool, in recent years, there is a large-scale increase in its output and the reduction of industrial costs, processing efficiency is high (is five times more than the ordinary), processing effect is good (can be very high requirements of the material for polishing), it is increasingly widely used. Diamond grinding tools are mainly metal, resin, ceramic, etc., which are classified according to the type of binder. Metal grinding tools mainly include the processing costs of different types of materials of iron, copper and cobalt base.Characterized by long service life, but the cost will be higher. Resin grinding tools, due to the relatively low production cost, the application of a few more, it is now also used for rough grinding to polishing, in fine-grained polishing is its biggest advantage

The process of stone renovation steps

Of stone material ground is renovated, have the following a few steps commonly, one, it is to use coarse grain lapping tool, the surface that will have damage "make even", do "cut a mouth", or already laid good uneven part "make even", of this process should have certain purify quantity commonly, when construction, want to notice integral level off sex. Second, the use of coarse-grained tools to grind stone, remove the processing of coarse grain. Also keep the construction surface level.Third, the process of fine grinding, this process to remove less, through 4-5 grit size number, so that the stone finish to meet the requirements of polishing. Finally, the polishing process. Stone renovation to achieve the requirements.
