All About Abrasives

For this week’s blog post we’re going to be discussing abrasives.


An abrasive is a material, often a mineral, that is used to shape or finish a workpiece through rubbing which leads to part of the workpiece being worn away by friction.


While finishing a material often means polishing it to gain a smooth, reflective surface, the process can also involve roughening as in satin, matte or beaded finishes. In short, the ceramics which are used to cut, grind and polish other softer materials are known as abrasives.


Abrasives are used in the form of grinding wheels, sandpapers, honing stones, polishes, cutoff wheels, tumbling and vibratory mass-finishing media, sandblasting, pulpstones, ball mills, and still other tools and products. Only through the use of abrasives is industry able to produce the highly precise components and ultrasmooth surfaces required in the manufacture of automobiles, airplanes and space vehicles, mechanical and electrical appliances, and machine tools


Interestingly, the use of abrasives goes back almost since the beginning of recorded history. Prehistoric men, for example, sharpened their tools and weapons by rubbing them together.


The first recorded manufacture of coated abrasives goes back to the 13th century when the Chinese used natural gums to bind crushed seashells to parchment.


At the turn of the century, coated abrasives took a giant step forward with the development of the new electric furnace grains, silicon carbide and aluminum oxide.


Through the Industrial Revolution, the post-World War II economic boom and a surging economy in the 1990’s, abrasives have always been a part of the production process
