摘要:
To provide a machine tool that is capable of executing center level adjustment of a plurality of tools mounted on a tool post against a workpiece having a larger diameter and that is also capable of reducing wasted time in non-cutting operation via equal stroke lengths of the tools. A machine tool (100) includes movement means (110), which has a first feed shaft (A) and a second feed shaft (B) that mutually intersect, and a plurality of tools (120), which are driven by the movement means (110) and respective blade edges of which are staggered in a stepwise fashion. The blade edges of the tools (120) are aligned with the second axis (B) due to the inclination of the tools (120) as a unit.
