ABSTRACT:
A control apparatus for controlling the amount of grinding of a belt material in a grinding machine wherein, for example, in the production process of making belts, a cylindrical belt material is ground on its back to finish its thickness to a standard dimension. The controlling apparatus is provided with a feed apparatus for feeding either the grinding member or the work to be ground to force it into contact with the other, a cam apparatus for regulating the feed stepwise up to the preset maximum feed position, and a thickness presetting means for presetting the final thickness of the work to be ground in the maximum feed position of the grinding member controlled by said cam apparatus. The control apparatus is capable of grinding reliably a work to be ground to a preset thickness, and the finishing thickness of the work to be ground can be altered with ease.
