ABSTRACT:
A machine tool essentially comprises a chuck or workpiece holding assembly (S) for rotating a workpiece (W) about a revolution axis (X) of a surface to be obtained on the workpiece, and a rotary composite tool (22) having a series of elementary tools (32.sub.1 . . . 32.sub.6) located at angularly spaced apart positions about an axis of rotation for the composite tool; each elementary tool has respective front cutting edges (40) substantially radial relative to such an axis of rotation. The axis of rotation for the composite tool is orthogonal to a plane tangent to the surface to be obtained on the workpiece and the composite tool is movable relative to the workpiece parallel to such a plane. The consecutive front cutting edges are arranged on the composite tool at decreasing spacings from its axis of rotation, and at decreasing spacings from the workpiece surface. The farthest front cutting edge from the axis of rotation is also the farthest cutting edge from the tangent plane.
