<p>The invention relates to a process and an apparatus for grinding and polishing parts, in particular wood parts, and proposes for optimizing the surface quality that an abrasive material be distributed in a box (2), in order to form a lower abrasive material layer, the parts (24) to be treated be laid on this first layer at the upper end of the box, then a second abrasive material layer (23) be distributed on this first layer and on the parts, the thickness of this layer corresponding to the depth of the immersing of the parts into the abrasive material, the box be made to vibrate, in order to shake the abrasive material, the abrasive material and parts being transported along the box to its lower end (21), the abrasive material be collected at the lower end of the box and returned to the upper end, where it is accumulated in order to form the first and second layer (22, 23). <IMAGE></p> |
