    摘要: An improved process for shaping the edge of a combustion chamber recess in the piston head of a finish-machined light-alloy piston is disclosed wherein the piston is moved past the oscillating charged carrier beam at an angle of inclination of 40.degree. to 50.degree., the charged carrier beam is caused to act on that portion of the rim of the combustion chamber recess which is to be refined by being remelted and the charged carrier rays are moved over said portion only once. The process presents the formation of cracks at the edge of the chamber.
