Abstract

Assembly is designed to be mounted in place of the head of a machine tool which incorporates digital control of the principal displacements of the device in relation to the piece, comprises a machining head driven by a motor and including a chuck for a cylindro-spherical cutter. The head can be adjusted in an oblique slide carried by a slide-block, itself able to slide radially with respect to an outer plate. This plate is carried at the end of a principal shaft mounted in bearings for continuous rotation about its axis and sinusoidal alternating translation along the same axis. which is brought by the principal displacements into the axis of the hole around which the cutting is to be made. The device is for machining oblique cuttings partic. in prepn. for welding at the connection of branch tubes for instrumentation or control rod mechanisms in the spherical base or cover caps of nuclear reactors. It resolves the problems encountered when a tube is connected obliquely rather than perpendicularly to a plane or spherical wall and the form required for the cutting to give a uniform weld section is more complex.
