Abstract: Disclosed is an alignment tool. A body of the alignment tool fits into a turret block, while a head holds a machine-tool. During the alignment process, the head and body are allowed to move relative to one another in two dimensions perpendicular to an axis of rotation of a spindle.

The axis of the head of the empty alignment tool, and thus the axis of any machine-tool held by the head, is aligned with the axis of the tapered workpiece and, thus, with the axis of the spindle. Once the machine-tool is aligned with the spindle, the head and body are tightly fastened together to preserve the alignment.
