Abstract:
1. A machine tool, comprising: an X-axis moving unit, a Y-axis moving unit, and a Z-axis moving unit for producing relative movements between a tool and a workpiece along the respective directions of an X-axis, a substantially vertical Y-axis, and a Z-axis, which differ from one another; a C-axis drive unit for rotating the workpiece about a C-axis parallel to the Z-axis; and a B-axis turning unit for turning the tool about a B-axis which is defined on the B-axis turning unit and is parallel to the Y-axis, wherein the tool is disposed in such a manner that a machining point of the tool substantially coincides with the B-axis, and the moving units, the drive unit, and the turning unit are controlled in such a manner that a work point of the workpiece substantially coincides with the machining point of the tool.
