Abstract
A device for washing machine parts, e.g. balls or rolls for roller bearings, having finely finished spherical or cylindrical outer surfaces, in connection with the manufacture thereof. The machine parts are fed one after the other through a washing chamber being axially symmetrical to the feed direction, a solvent being injected under pressure into the chamber in such a direction that the solvent flows with a rotational velocity component around the feed direction and strikes the finely worked surfaces of the machine part at a small angle but with great power, whereby contaminants being soluble in the solvent as well as other contaminants being bound to the surface are effectively removed therefrom.
