A cutting tool includes a tool holder, having a holder pocket with a pocket opening, and a cutting member releasably retained therein. The tool holder includes an adjustment cavity that includes circumferentially merging threaded and guiding bore portions. The tool holder further includes an adjustment arrangement that includes an adjustment member including a wedge adjustment portion and a guiding portion integrally formed therewith. The adjusting arrangement further includes an adjustment screw. The wedge adjustment portion is located in the pocket adjustment region and the guiding portion is located in the guiding bore portion and partially protrudes into the threaded bore portion. The adjustment screw is threadingly rotatable between a first rotated position and a second rotated position, and in the second rotated position the adjustment member, and thus the cutting member, is located closer to the pocket opening than in the first rotated position.

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.

A milling cutter (100) comprising: a cartridge (33) that has a tip (32) fixed thereto; a body (10) that has a pocket (15) formed therein into which the cartridge (33) is inserted; and a fixing tool (40) that fixes the cartridge (33), wherein the body (10) has a fixing tool insertion hole (16) that is adjacent to the pocket (15) on the radial direction inner side thereof, and a partitioning wall (17) between the pocket (15) and the fixing tool insertion hole (16), the fixing tool (40) that has been inserted into the fixing tool insertion hole (16) exerts a radial direction outward force on the partitioning wall (17), the pocket (15) is formed so as to produce a counterforce that resists the radial direction outward force acting on the cartridge (33) via the partitioning wall (17), and the cartridge (33) is fixed in the pocket (15) on the basis of the radial direction outward force.

A cutting tool includes a tool holder, having a holder pocket with a pocket opening, and a cutting member releasably retained therein. The tool holder includes an adjustment cavity that includes circumferentially merging threaded and guiding bore portions. The tool holder further includes an adjustment arrangement that includes an adjustment member including a wedge adjustment portion and a guiding portion integrally formed therewith. The adjusting arrangement further includes an adjustment screw. The wedge adjustment portion is located in the pocket adjustment region and the guiding portion is located in the guiding bore portion and partially protrudes into the threaded bore portion. The adjustment screw is threadingly rotatable between a first rotated position and a second rotated position, and in the second rotated position the adjustment member, and thus the cutting member, is located closer to the pocket opening than in the first rotated position.

A minor cutting edge has a first minor cutting edge and a second minor cutting edge that extends inward of the insert in a direction of an insert short side face axial line, as the second minor cutting edge extends from the first minor cutting edge in a direction of an insert major face axial line. A flank face of the second minor cutting edge is inclined outward of the insert in the direction of the insert short side face axial line, as the flank face extends from the second minor cutting edge in the direction of an insert long side face axial line, and is inclined outward of the insert in the direction of the insert short side face axial line, as the flank face extends from a major face adjacent to the flank face in the direction of the insert major face axial line.

A bevel gear manufacturing face cutter head (2) for face hobbing and face milling wherein the cutter head includes positive blade seating surfaces (16, 18) and the capability to clamp the blades (8) tight to the positive seating surfaces and to adjust the cutting blades radially after they are pre-clamped and axially located.

In an embodiment, a cutting tool includes a holder and a cutting insert. The holder is elongated and includes an insert pocket that is located on a side of a first end. The cutting insert is secured to the insert pocket. The cutting tool further includes a clamp that fastens the cutting insert in the insert pocket, and a screw that comes in contact with the cutting insert and is secured to the insert pocket. The screw includes a first surface including a first engagement portion on a first surface that is located on a side of the first end. The first engagement portion is located within a through-hole included in the screw in a front view of the first end.

A bevel gear manufacturing face cutter head (2) for face hobbing and face milling. The cutter head has blade positioning slots (20) having a four-sided shaped cross-section and positive blade seating surfaces (22, 24). The cutter head also has the capability to clamp cutting blades (8) tight to the positive blade seating surfaces and to adjust the cutting blades radially after they are pre-clamped and axially located.

Provided is a cutting edge position adjustment mechanism for moving a cutting edge member mounted on a tool body with respect to the tool body to adjust the position of a cutting edge. The cutting edge position adjustment mechanism is equipped with a shaft member that extends between the tool body and the cutting edge member and threadably engages with the tool body and a nut member that threadably engages with the shaft member and abuts against the cutting edge member; a first screw section that threadably engages with the tool body and a second screw section that threadably engages with the nut member are provided coaxially on the shaft member at different positions along the direction of an axis line of the shaft member; and the thread pitch of the first screw section and the thread pitch of the second screw section are different from each other.

In an embodiment, a cutting tool includes a holder that is a columnar body and includes a pocket in which an insert disposed. The pocket includes a first surface in contact with the insert, a second surface, and a projecting portion. The second surface is disposed further forward in a rotational direction of a rotational axis than the first surface, and disposed on a radial inner side of the holder. The projecting portion is disposed closer to a radial outer circumferential side of the holder than the first surface and projects forward in the rotational direction of the rotational axis. The second surface is inclined and comes closer to an outer circumference of the holder as going forward in the rotational direction of the rotational axis, in a front view of a first end.
