Abstract
A cutting head operated by a centrifugal force according to an embodiment of the present invention includes: an external housing that is rotatable; an internal housing installed within the external housing so as to be able to advance and retreat in a diameter direction, advanced toward a cut surface of a workpiece positioned outside the external housing by a centrifugal force according to rotation of the external housing, and retreated in a direction that becomes distant from the cut surface by an elastic member while the centrifugal force disappears; and a cutting tool unit provided in the internal housing and processing a groove in the cut surface while being advanced and retreated by a micro advance and retreat member.
Claims20
A cutting head operated by a centrifugal force comprising:
- an external housing that is rotatable;
- an internal housing installed within the external housing and configured to advance and retreat in a diameter direction, wherein the internal housing advances toward a cut surface of a workpiece positioned outside the external housing by a centrifugal force to generated by rotation of the external housing and retreats away from the cut surface by an elastic force of an elastic member installed on the internal housing when the centrifugal force is decreased by slowdown of the rotation of the external housing;
- and
- a cutting tool unit provided in the internal housing and processing a groove in the cut surface while being advanced and retreated by a micro advance and retreat member which is electrically driven to move in a scale smaller than the movement of the internal housing.
