Abstract (en)
A blade-replaceable cutter, incorporating a disc-shape cutter body (11) having a plurality of joining seats (11a) for replaceable blades (13) formed on the same circumference in one side surface of an outer portion thereof. A mechanical unit for locating and securing the replaceable blades (13) to the joining seats (11a) is provided and the replaceable blade (13) is formed into a single side bevel circular knife shape and having a cutting edge line which can be changed by rotating the replaceable blade (13) about an axis perpendicular to the joining seat (11a). The replaceable blade (13) is joined in such a manner that portion of the leading end of the replaceable blade (13) projects over the outer periphery of the cutter body (11). Substantially overall portion of the side face of the replaceable blade which does not project over the outer periphery of the cutter body (11) does not project over the side surface of the cutter body (11) in a direction of the axis of rotation of the cutter and the portion of the leading end of the replaceable blade (13) projecting over the outer periphery of the cutter body (11) makes a positive radial clearance angle θ.
