Grinding and polishing involve a step-by-step reduction of the roughness of a surface to access the undeformed structure. Grinding uses fixed abrasives—the abrasive particles are bonded to the paper or platen—for fast stock removal. Polishing uses free abrasives on cloth; the abrasive particles are suspended in a lubricant and can roll or slide across the cloth and specimen. This process is based on using abrasive particles in progressively finer grain sizes. In materialographic grinding, these abrasives are bonded in resin or metal matrix, with the most frequently used grinding abrasives being silicon carbide particles. These particles are often used when working with softer, medium or hard materials, composites and electronics. It is also possible to utilize diamond particles for harder components like ceramics, carbides, glass or stone.
fused aluminum oxide products do not have a known shelf life. As long as the product is maintained in the original sealed container and stored in a cool, dry, ventilated area, our product will last indefinitely
We can supply the sample if we have ready parts in stock, but the customers have to pay the sample cost and the courier cost.
Hardness is rated from A-Z with ‘A’ being the weakest bond and ‘Z’ being the strongest. A weak bond is preferred for grinding harder materials while a stronger bond is desired for softer materials. A typical weak bond for steel would be in the ‘F, G or H’ range. A
A typical grinding wheel specification consists of the grit type, the grit size, the hardness, the structure and the bond. A typical grinding wheel specification would be A60-I10-VS. ‘A’ is the grit type (aluminum oxide), ’60’ is the grit size, ‘I’ is the relative hardness, ’10’ is the structure, and

Mohs hardness (according to Friedrich Mohs, 1773 – 1839) ascribes a relative hardness value to certain known minerals on a scale ranging from 1 (talc) to 10 (diamond). Accordingly, a mineral is considered harder than another if it can scratch the latter. Please note that these values merely form an
