Abstract
A turning tool is arranged at a tool spindle () of a composite working lathe () to improve working efficiency. A composite working lathe () includes a first workpiece headstock () placed on a bed (). A chuck () of a workpiece spindle () is rotated as holding a workpiece (K.sub.). A tool headstock () arranged at a carriage () is rotated about B-axis while being linearly moved in the directions of X-axis, Y-axis and Z-axis. The tool headstock () operates a mill tool () and includes a comb-shaped cutting tool rest () having turning tools attached at the opposite side of a housing in a comb-shaped manner, so that turning processing can be performed with tool indexing in a short time.
