ABSTRACT:
An abrasive belt grinder is provided which includes the following components: (1) a pair of parallel, spaced rollers mounted to a table; (2) an endless abrasive belt mounted between the rollers, the upper portion of the belt defining a substantially planar grinding surface; and (3) a platen fixedly mounted under the upper portion of the abrasive belt to provide support for the workpiece, the platen including a plurality of parallel slots which are angled with respect to the direction of travel of the abrasive belt to facilitate cooling of the platen.
Another aspect of the invention is a method for grinding a workpiece on an abrasive belt grinder which includes the step of placing a workpiece on the grinding surface to initiate grinding of the underside of the workpiece, displacing the workpiece from side to side along the grinding surface so that grinding is effected in a uniform fashion, and cooling the platen and the workpiece by permitting cooling fluid to circulate between the bars of the platen while grinding is taking place.
