A device for processing, particularly deburring, rounding and/or hardening component part contours, is provided, including a compressed air channel for supplying compressed air, an abrasive channel for supplying abrasive material and an ejector nozzle for ejecting the abrasive material. The ejector nozzle is positioned with its axis essentially transverse to the longitudinal extension of the compressed air channel and of the abrasive channel and the acceleration of the abrasive material takes place essentially in the ejector nozzle.

Device for processing component part contours

A method and an apparatus for edge shaping in a high-pressure fuel reservoir which has an elongated tubular casing element equipped in the longitudinal direction with a continuous recess which forms the interior space of the high-pressure fuel reservoir and is open at at least one end, the recess opening into at least one passthrough orifice, that together with the continuous recess forms a peripheral edge. An elongated actuation element, whose end inserted into the continuous recess is equipped with a surface segment inclined with respect to the longitudinal axis of the continuous recess, is inserted into the continuous recess, the surface segment acting at least indirectly on a pressure element introduced into the continuous recess so that a surface portion of the pressure element is pressed against the peripheral edge, and a smoothing of the edge contour is achieved because of a material displacement in the region of the edge.
