Abstract: The invention concerns a lathe which is designed as a processing center and with which other working processes can be carried out in addition to turning work. The tool post (5) contains a processing turret (9) which can be rotated around a vertical axis as well as secured at various angles. The processing turret is equipped with a spindle unit (that can be powered) 11 to hold the tools and has at least one holding fixture (13) for temporary attachment of tools or working units. For tool exchange purposes the tool magazines (14, 15) are placed on the lathe; these allow for a quick exchange of tools and/or tool units. The lathe according to the invention allows a complete working of basic cylinder shapes and--based on retooling and transportation time alone--makes superfluous several machine tools which can perform only one work operation.
