ABSTRACT:
A machine for grinding objects, especially helical-or coil-type springs whose opposite ends are to be ground, includes a pair of rotary grinding discs having grinding surfaces spaced in axial direction from each other so as to define a work station. A plate-shaped element having a region mounted for turning movement relative to the work station intermediate the grinding surfaces is formed with a plurality of apertures, each of which is adapted to receive an object which is to be ground by contact with the grinding surfaces. Channels are provided in the plate-shaped element and connect the apertures with a source of fluid for supplying the latter to the apertures.
