The History of Abrasives
Stone used in building the Pyramids of Egypt were smoothed with a naturally "bonded" abrasive--sandstone! Around 2100 B.C. a creative Egyptian engineer mounted a circular wheel on a crude sort of lathe and ground bronze tools and ornaments, launching the art of cylindrical grinding. During the Middle Ages, armor and swords were ground and polished. 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. Over the years, sanding became even more popular as a number of new products emerged on the scene and on the production line. Sanding had an impact on all these products--wood and metal as well as glass. Henry Ford, for example, did more for the metal grinding industry than anyone in history.
Ford realized that an ounce of extra weight in any part acted and reacted upon every part. His demand for light parts of great strength created the first big tonnage of alloy steels, whose sensitivity to heat treatment not only fulfilled his requirement of strength without weight but called for grinding to finish instead of cutting with metal tools.
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, and they will continue to do so in this millennium.
