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. To align the alignment tool, a workpiece is inserted into the spindle. As the workpiece spins, a machine-tool cuts a taper in it. An “empty” alignment tool is brought to bear against the tapered workpiece. 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.
