Abstract:
There is provided a machine tool for suppressing the adverse effect of run-out of the rear end of a spindle on the rotation detection accuracy when processing a workpiece within a processing area. The machine tool includes a rotation driver, the spindle that is rotated by the rotation driver, a rotational angle detector that is provided to face a part forming the spindle in order to detect a rotational angle of the spindle, and at least two bearings that support the spindle and are arranged on a side of the processing area with respect to the rotation driver. The rotational angle detector is arranged at a position on the side of the processing area with respect to the rotation driver, the position being on the side of the processing area with respect to the bearings, on a side of the rotation driver with respect to the bearings, or between the bearings.

Claim (Index 7):
The machine tool according to  claim 3 , wherein said rotational angle detector is provided at a position facing a surface of a spacer provided between one of the bearings and the other.
