摘要： A rotary cutting tool is provided which, although it has a simple configuration, allows the arrangement of each cutting edge to be easily adjusted. A first cartridge mounting seat has an upper wall surface opposing an outer side surface of a cartridge and further has a first recessed part into which a protrusion is inserted and which comes into contact, at a bottom thereof, with a leading end of the protrusion. A second cartridge mounting seat has an upper wall surface opposing an outer side surface of a cartridge and further has a second recessed part into which a protrusion is inserted and which comes into contact, at a bottom thereof, with a leading end of the protrusion. A depth of the second recessed part is greater than a depth of the first recessed part. An amount of protrusion P of the protrusion is equal to or greater than the depth of the second recessed part.

摘要： A rotary cutting tool for slotting and a cutting insert replaceably mounted to such a rotary cutting tool. The cutting insert is mounted to an insert pocket of a tool body of the rotary cutting tool and is pressed by an elastic pressure portion provided in the tool body. The cutting insert has an upper surface, a lower surface and four peripheral side surfaces. The top and lower surfaces have an inclined surface pressed by the elastic pressure portion. When the cutting insert is mounted to the insert pocket, the inclined surface of the upper surface is pressed by the elastic pressure portion. The inclined surface is inclined with respect to a cross section of the cutting insert such that the lower surface and two peripheral side surfaces of the cutting insert are contacted with the insert pocket by pressure of the elastic pressure portion.

摘要： A blade positioning structure of a disposable milling cutter includes a cutter body and a disposable blade. The cutter body is peripherally provided with a blade seat. By passing a screw through the disposable blade and the blade seat, the disposable blade is locked to the blade seat. The blade seat has a blade seat surface and a sidewall; the blade seat surface has a groove; the disposable blade has a bottom surface provided with a projection corresponding in shape to the groove; and when the disposable blade is locked to the blade seat, the blade seat surface and the groove of the latter lie respectively and tightly against the bottom surface and the projection of the former.

摘要： A helical blade cutter including multiple linear blades attached to an outer circumferential surface of a round body having an outer surface formed into a cylindrical circumferential surface. The blades tilt to a given helix angle α from a straight line on the outer circumferential surface parallel to a rotational central axis O. Blade attachment surfaces are formed on the outer circumferential surface of the round body at given intervals in the circumferential direction. The blade attachment surfaces tilt to an angle same as the helix angle α of the blade while tilting to a rake angle β in a direction of an elevation angle from a tangent to the outer circumferential surface. The blades are each attached to a blade attachment part through intervention of a chip holder that allows detachment of the blade.

摘要： The present invention relates to an insert for slot milling, and more specifically, to an insert for slot milling which can smoothly form a front end surface of a concave portion of a slot formed at a cutting target, and provides a safe use thereof by preventing the erroneous installation of cutting inserts coupled with insert-installation seats on both sides of a milling cutter body to prevent damage of the cutting inserts and the milling cutter. To this end, the present invention is characterized in that the plurality of cutting inserts are provided around the slot milling cutter body, one of two cutting inserts protrudes with respect to one side of the milling cutter body and the other protrudes with respect to the opposite side of the milling cutter body, and two cutting inserts are formed with different structures to prevent the erroneous installation thereof on the insert-installation seats prepared on both sides of the milling cutter body.

摘要： A saw tooth for a saw blade that is attached in a longitudinal direction thereof on the saw blade body to extend away, at least in part, from the saw blade body. The saw tooth is formed with a cutting-face part having a cutting face, a height of which extends in the longitudinal direction and a width of which extends perpendicularly to the longitudinal direction. The width of the cutting face is greater than a height of the cutting face.

摘要： A rotary cutting tool, such as a slotting cutter, includes a cutter body rotatable in a predetermined direction on a central axis perpendicular to a plane of the cutter body. A plurality of cutting insert-receiving pockets are formed at predetermined locations about the cutter body. A cantilevered member can be integrally formed in the cutter body or attached to the cutter body as a separate component. A tip of the cantilevered member at least partially extends into each insert-receiving pocket such that the cantilevered member exerts a biasing force against a cutting insert at a location so as to counteract a tendency of the cutting insert to rotate within the insert-receiving pocket during a cutting operation.

摘要： A cutting insert includes an insert body portion and a plurality of projecting portions provided integrally with the insert body portion. The projecting portion includes a cutting edge and includes projecting portion upper and lower surfaces, two projecting portion side surfaces, and a projecting portion side end surface extending therebetween. In the projecting portion, a round corner surface extends between the projecting portion upper surface and the projecting portion side end surface. The cutting edge is formed so as to include a corner formed along an edge of the round corner surface and such that the projecting portion side surface serves as a rake face. The projecting portion is designed such that a length between the two projecting portion side surfaces is smaller than a diameter of an inscribed circle defined on the insert body portion.
