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.
