摘要
A cutter head assembly including: (a) a main body which has a cutting-blade receiving bore and a clamping-member receiving bore partially interfering with the cutting-blade receiving bore; (b) a cutting blade received in the cutting-blade receiving bore and having a flat surface as a part of an outer circumferential surface thereof and parallel to an axis of the cutting blade; and (c) a cylindrical clamping member received in the clamping-member receiving bore and having a fitting portion and a cam portion. The cylindrical clamping member is fitted at the fitting portion in the clamping-member receiving bore. The cam portion has a cam surface whose radial distance from an axis of the fitting portion changes in a circumferential direction of the cylindrical clamping member. The cylindrical clamping member is rotatable about the axis of the fitting portion so that the cam surface is brought into contact with the flat surface of the cutting blade, for thereby pressing the cutting blade onto an inner circumferential surface of the cutting-blade receiving bore.
