Abstract
A polygonal turning machine with a rotating knife head, and a workpiece carrier rotating synchronously to the knife head, the carrier being arranged on a support, characterized in that, the axis of the workpiece carrier is able to be brought into a coaxial position to the axis of rotation of the knife head.
Claims9
A combination polygonal and cylindrical turning machine, comprising
- a rotatable knife head defining an axis of rotation,
- cutter means for a polygonal turning mounted on said knife head,
- additional cutter means for a cylindrical turning mounted on said knife head,
- a support,
- a workpiece carrier adapted to hold a workpiece and rotatably mounted on said support, said workpiece carrier defining a workpiece carrier-axis,
- means for rotating said workpiece carrier synchronously to said knife head,
- guide means for selectively bringing said workpiece carrier-axis from a non-coaxial position into a coaxial position to said axis of rotation of said knife head such that said cutter means and said additional cutter means operatively project onto the workpiece held by said workpiece carrier, respectively, to perform thereon a polygonal turning and a cylindrical turning, respectively, in each of said positions.
