Abstract
A machine tool includes a movement device, which has a first feed shaft and a second feed shaft that mutually intersect, and a plurality of tools, which are driven by the movement device and respective blade edges of which are staggered stepwise. The blade edges of the tools are aligned with the second axis due to the inclination of the tools as a unit. The machine tool 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 is also capable of reducing wasted time in non-cutting operation via equal stroke lengths of the tools.
