A procedure for smoothing off the edges of springs is characterised in that the springs are heated by a laser beam until the desired smoothing off of the edges takes place as a result of softening or fusing of the surface, whereupon the heating operation is stopped. The procedure can be used in an advantageous manner for smoothing off the edges of burr which has developed in the manufacture of micro sliding contacts by punching. The laser beam is preferably defocused, that is, it is focused on a point in front of or behind the surface to be exposed to the laser beam, which results in "soft" radiation. An especially high surface quality can be achieved due to the avoidance of mechanical rework and due to the contactless working. This procedure is especially cost-effective, since it is also easy to automate. …<IMAGE>… |
