Abstract:
A method for cutting an inner circumferential surface of a rotating hollow cylindrical workpiece includes: holding the workpiece with a chucking device such that a side surface of the workpiece on a first side in an axial direction of the workpiece is in contact with a contact surface of the chucking device; setting an intersection angle between a rotational center line of the workpiece and an imaginary straight line to an angle smaller than 45 degrees, the straight line being parallel to an axis line of a button tip and intersecting with the rotational center line; and setting a feed direction of the button tip to the inner circumferential surface to a direction from a second side in the axial direction of the workpiece toward the first side in the axial direction thereof, and cutting the inner circumferential surface by use of the button tip rotating about the axis line.

Claim (Index 4):
A cutting apparatus that cuts an inner circumferential surface of a rotating hollow cylindrical workpiece, the cutting apparatus comprising:\n a chucking device that has a contact surface to be in contact with a side surface of the workpiece on a first side in an axial direction of the workpiece, and that is configured to hold the workpiece; a linear tool with a button tip mounted at a distal end thereof; a head that has the tool mounted thereon such that an intersection angle between a rotational center line of the workpiece and an imaginary straight line parallel to an axis line of the button tip and intersecting with the rotational center line of the workpiece is smaller than 45 degrees, and that rotatably supports the tool; and a feed mechanism configured to feed the button tip to the inner circumferential surface of the workpiece in a direction from a second side in the axial direction of the workpiece toward the first side in the axial direction thereof.
