Abstract
A turning tool is arranged at a tool spindle (102) of a composite working lathe (1) to improve working efficiency. A composite working lathe (1) includes a first workpiece headstock (20) placed on a bed (10). A chuck (24) of a workpiece spindle (22) is rotated as holding a workpiece (K.sub.1). A tool headstock (100) arranged at a carriage (50) is rotated about B-axis while being linearly moved in the directions of X-axis, Y-axis and Z-axis. The tool headstock (100) operates a mill tool (110) and includes a comb-shaped cutting tool rest (150) 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.
