Abstract: An apparatus for machining axially symmetrical workpiece surfaces. The apparatus includes two vises for the workpiece that is to be machined, and two headstocks, each of which has an arbor for a respective tool, with the two tools being aligned with one another. The ends of the two tools that face one another are supported against one another in such a way that the tools can be shifted axially relative to one another.

Abstract: A chain magazine for shop machines, especially for apparatus for handling workpieces, including at least one endless rotating chain, preferably a roller chain, that is guided over sprocket wheels. Holders, for accommodating tools, workpieces, or the like, are mounted on the chains via connectors that are provided on at least two places of attachment, preferably pins, of chain links of the chains. Each connector, in a portion thereof that is disposed beyond the sprocket wheels, is provided with at least one support part via which the connector is supported against at least an adjacent chain link of the chains.
