ABSTRACT:
The cutter head for the traced rough turning of rod-like workpieces includes a rotary base ring provided with a plurality of radial guideways. A supporting member in the form of a slide carriage movable on the radial guideways supports an elongated blade holder which is pivotable about a hinge point laterally offset from the guideways. The free end of each blade holder carries an inserted blade and is spring biased against the workpiece at the center of the base ring by a set of biasing springs supported on the slide carriage. A tracer pin adjoins the cutting blade and its vertical position is adjustable relative to the main cutting edge to determine the thickness of the cuttings. The point of contact of the cutting edge relative to the center of the hinge joint forms with a tangent line passing through the contact point an angle between 10.degree. to 25.degree..
