A semi-portable grinder which is usually suspended from a crane, ceiling, or from a fixture to provide flexibility in grinding operations. The conventional type of swing grinder uses a snagging wheel which makes it possible to remove considerable metal very rapidly.
One of the disadvantages of the swing grinder fitted with a snagging wheel is that it isdifficult to obtain a smooth surface. Abrasive belt swing grinders are available which combine the rapid moving features of the snagging wheel with the even surface grinding features of a disk grinder. An abrasive belt swing grinder removes a specific amount of metal, as required, resulting in a smooth and even surface. The abrasive belt is electrostatically coated with an aluminum oxide grinding material, and travels at a speed of about 1370 dmin (4500ft/min).
