Abstract
A machine tool includes a workpiece spindle unit () including a workpiece spindle () and a workpiece spindle motor () and includes a tool spindle unit () including a tool spindle () and a tool spindle motor. The machine tool further includes a first-axis movement mechanism () and a second-axis movement mechanism () relatively moving, in a plane including an axis of the workpiece spindle () and an axis of the tool spindle (), the workpiece spindle unit () and the tool spindle unit () in a first axis direction and a second axis direction intersecting the first axis direction, respectively, and further includes a controller. The tool spindle unit () is arranged such that the axis of the tool spindle () intersects the axis of the workpiece spindle (). The controller relatively moves the workpiece spindle unit () and the tool spindle unit () along the axis of the tool spindle () through combined operation of the first-axis movement mechanism () and second-axis movement mechanism (), thereby grinding a workpiece (W) with a cup grindstone (T).
