Abstract
A procedure is described for the lapping of a valve seat 2 and shutter 3 coupling that consists of the phases of coupling the shutter 3 with a particular valve seat 2; producing a relative motion of rotation about a common axis C for the shutter 3 and the valve seat 2; supplying an abrasive fluid 15 between the shutter 3 and the valve seat 2 in relative rotation; simultaneously with the rotation between the shutter 3 and the valve seat 2, generating by means of two generators 21 at least two alternate direct transversal motions not in parallel with the common axis C, not in parallel with each other, and having different frequencies. Also described is an apparatus 1 making it possible to implement this procedure. <IMAGE>
