Abstract: The invention relates to a device for dressing a grinding wheel, comprising a sleeve to hold a corundum rod laterally and to guide it along its longitudinal axis, a ram to apply constant thrust force onto the corundum rod held in place and guided in the sleeve, to bring it into contact with the grinding wheel, means of rigidly connecting the ram shaft to the end of the corundum rod, and linear guide means for the sleeve for translating the corundum rod parallel to the axis of the grinding wheel while keeping the rod pressed against the grinding wheel with a constant force. Application to a centerless grinder in which the grinding wheel is used to grind nuclear fuel pellets.

Abstract: The invention relates to a device (1) for the insertion, guidance and evacuation of cylindrical parts to be ground in a centreless grinder (10). According to the invention, micrometric means (4, 40, 41) for adjustment of the alignment of the guides at the entry (3) to and the exit (5) from the guide chute (2) are provided and these micrometric adjustment means are independent from each other. The invention enables very precise adjustment of the alignment and prevents any shift of the parts.
