ABSTRACT:
The method relates to the manufacture of a piston. This piston comprises a head and a stem extending transversely with respect to the head. A profiled element in bar form is first taken, the profile of which envelops that of the piston. This profiled element is cut up into slices, the width of each slice being at least equal to the maximum diameter of the piston, and the material of the profiled element slice which extends relatively beyond the desired profile for the piston is removed by machining. The method is particularly useful for manufacturing remote-controlled actuators for valves.
