Lathe apparatus is disclosed which in one form is an automatic turret lathe in which a single turret head is provided that can support a plurality of tools for performing machining operations on inside and outside surfaces of a workpiece carried on the live spindle of the lathe. The axis of the turret head is disposed at a preferred angular relationship to the axis of the live spindle, and the receiving or mounting surfaces for the inside and outside machining tools are disposed alternately around the axis of the turret head in planar arrangements that provide optimum operating conditions for utilizing the outside and inside machining tools on a single turret head. An attachment for preturning of workpieces is provided which can be mounted on the headstock to perform cutting operations wherein the cutting tool is moved in response to movement of the turret carriage of the turret head. Another attachment is provided to facilitate supporting of the workpiece during the preturning of the workpiece. The lathe apparatus also includes a tailstock construction for synchronous axial adjustment with the live spindle and also to permit pivotal movement of the tailstock relative to the live spindle. An improved automatic feed of bar stock is also provided.
