How to choose abrasive to furbished stone

Abrasive materials Category:

The abrasive material is used for grinding, and now the general classification ordinary abrasive, super abrasive two categories:

1, ordinary abrasive

Common abrasives include (1) type corundum (corundum, corundum, etc.), its main chemical composition of A1203 (aluminum oxide), (2) type silicon carbide (black silicon carbide, green silicon carbide), the main chemical components of the SIC (silicon carbide). Their hardness are corundum, hardness 2000-2200 kgf / mm; corundum, hardness 2200-2300 kgf / mm; black silicon carbide, hardness 3100-3300 kgf / mm; carbonized green silicon, hardness 3200-3400 kgf / mm; particle size from # 4 - micronized W0.5 (or finer), the hardness of the order that we can sort out the processing of granite green silicon carbide, black silicon carbide, marble processing It is corundum (soft), black, green silicon carbide (hard); from the cost of materials are sequentially look green silicon carbide, black silicon carbide, white fused alumina around the abrasive can be made of inorganic abrasive tools, including magnesite, ceramics and the like; organic abrasive tools, including phenolic, unsaturated resins, epoxy and the like (also includes sandpaper), which constitute the ordinary grinding tools abrasive grinding tools.

2, ultra-hard abrasive

Superabrasive diamond belongs to, its processing history is a relatively long, but as more use of the last three decades a large number of industrial production, its hardness 8000-10000 kgf / mm; hardness is the highest processing when the material is micro-cutting mechanism, so it is the preferred cutting tool, in recent years there is a massive increase in its production and reduce industrial costs, high efficiency (which is five times more than normal), good processing effect (it may claim high polishing materials), so it's increasingly widespread application. Diamond grinding tools are metal, resin, ceramic, etc., which are classified according to the type of binding agent, metal grinding tools mainly include iron-based, these types of copper-based, cobalt-based, it It determines the processing costs of different types of materials, as the use of grinding tools, from the most coarse particle size (# 20), often to the fine grain size # 400 to date, carried out using; which is characterized by long life, but the cost will be higher. Resin abrasive tool, due to the relatively low production costs, apply to relatively more, it is now also used for coarse grinding to polishing, grinding and polishing in terms of fine-grained is its biggest advantage; ceramic diamond grinding in recent years the fastest growing tools in its processing performance, take long metal finish, avoid short resin finish, technically good advantage, but because of cost reasons, have not seen the stone used in the refurbishment.
