Rubber-bonded abrasive wheels

Rubber. Both natural and synthetic rubber are used as bonding agents for abrasive wheels. Rubber-bond wheels are ideal for thin cut-off and slicing wheels and centerless grinding feed wheels. They are more flexible and more water-resistant than resinoid wheels. 

The bond in abrasive wheels may be ceramic, silicate of soda, resin, shellac, rubber, or magnesium oxychloride. 

Important amonnts of cryolite are used in the ceramic indnstry, the greatest consumption occurring in the manufacture of opal glass and enamels. Less widely known is cryolite s extensive nse as a filler for abrasive wheels, especially the resin- and rubber-bonded types. Another apphcation is in flux coatings for welding rods, particularly those used to join aluminum.

Modem civilization would not be possible without bonded abrasive products. By the year 1825 sand, emeiy, and even diamond were being bonded together with shellac for use in abrasive sticks and wheels. Rubber bonded wheels were introduced in 1857, the sodium silicate and the vitrified bond just after the Civil War, and the phenolic resin bond in 1923. The metal bond was introduced for diamond wheels in 1940. 

Extensive ranging of abrasive wheel geometries, abrasive materials (aluminum oxide, emery, corundum, diamond. Cubic Boron Nitride (CBN)), grain size, hardness grading and bond types (resin, vitrified glass, rubber, metal) are available.
