摘要： A cutting tool includes a main body. The main body includes a distal end surface, a rear end surface, and a side surface. A spiral first groove and a spiral second groove are formed on the side surface of the main body. The first groove has at least four installation surfaces. The first installation surface is located on a most rear end surface side. The second installation surface is located closer to a distal end surface side with respect to the first installation surface. A length from the first installation surface to the second groove in a circumferential direction along the rotation direction of the main body is set to a first length. A length from the second installation surface to the second groove in the circumferential direction is set to a second length. The first length is longer than the second length.

摘要： A rotary cutting tool has a cutting body and a plurality of cutting inserts, including a first insert removably secured in a first pocket and a second insert removably secured in a second pocket. The first pocket opens out at a forward end surface of the cutting body, having a seat surface with an axial support wall transverse thereto, and the second pocket is located axially rearward of the first pocket. The first insert has opposing front and back end surfaces, with a peripheral side surface extending therebetween which is in contact with the seat surface and the axial support wall. A first major cutting edge of the first insert axially overlaps with a second major cutting edge of the second insert, and in a side view of the cutting tool, a raised shoulder surface adjacent the axial support wall is at least partially obscured by the second insert.

摘要： A cutting insert according to an embodiment of the present invention has an upper surface, a lower surface, a side surface connected to each of the upper surface and the lower surface, and a cutting edge located along an intersection of the upper surface and the side surface. The upper surface has a land surface disposed along the cutting edge, a rake surface which is located further inside than the land surface and is inclined so as to have a smaller height as departing from the land surface, and a bottom surface located further inside than the rake surface. The rake surface has a projection-shaped first region and a concave-shaped second region which are alternately disposed along the bottom surface. The first region has a first recess that reaches the second region adjacent to the first region.

摘要： A cutting insert comprises a first surface sequentially including a first and second inclined surface. The first inclined surface is inclined toward the second surface, going inward from the edge at a first inclined angle on a basis of a perpendicular plane perpendicular to a central axis extending between the first surface and a second surface. The second inclined surface, located more inward than the first inclined surface, is inclined toward the second surface at a second inclined angle different from the first inclined angle on the basis of the perpendicular plane. An intersecting part of the first inclined surface and the second inclined surface includes a first part located at a highest position in a region of the intersecting part along the second side surface. A cutting tool with the cutting insert, and a method of producing a machined product using the cutting tool are provided.

摘要： A cutting insert mounting system adapted for a cutting tool in which, by using a tightening screw, a cutting insert is detachably mounted on an insert mounting seat. A central axis of a screw hole of the insert mounting seat is inclined with respect to a normal direction of a bottom wall surface of the insert mounting seat. When the cutting insert is placed on the insert mounting seat, on a virtual plane defined to expand the bottom wall surface, a central axis of the screw hole is shifted from the central axis of a through hole of the cutting insert to the side of one of two side wall surfaces of the insert mounting seat. On the virtual plane, an axis shift direction of the central axis of the screw hole and an inclination direction of the central axis of the screw hole are different.

摘要： A cutting insert including a first end surface, a second end surface and a peripheral side surface extending therebetween. The first and second end surfaces each having one substantially quadrangular portion and two substantially semicircular portions which are respectively joined to two opposing sides of the substantially quadrangular portion. An intersecting edge between each of the first and second end surfaces and the peripheral side surface is provided with a cutting edge. The cutting edge is formed in at least part of the substantially semicircular portion. At least part of a portion of the peripheral side surface which is adjacent to the substantially quadrangular portion of each of the first and second end surfaces, and at least part of a portion of the peripheral side surface which is adjacent to the substantially semicircular portion, each have a function of coming into contact with an insert seat.

摘要： A front and back chamfering rotary milling cutter includes a cutter body including an insert pocket and a star-shaped indexable cutting insert releasably retained in the pocket. The cutting insert has star-shaped upper and lower surfaces connected by a peripheral surface intersecting each of the upper and lower surfaces. The cutting insert includes a plurality of circumferentially alternating inner and outer corner portions. A cutting portion is defined by each outer corner portion together with an adjacent first inner corner portion rotationally forward thereof and an adjacent second inner corner portion located rotationally rearward thereof. Each cutting portion includes a front chamfering cutting edge extending from the outer corner portion to the first inner corner portion and a back chamfering cutting edge extending from the outer corner portion to the second inner corner portion.

摘要： A cutting insert has opposing first and second end surfaces, and a peripheral side surface (connecting the end surfaces. A central axis penetrates the two end surfaces. The peripheral sure surface includes an outwardly inclined first side surface part related to a major cutting edge and a second side surface part related to a minor cutting edge. The outwardly inclined first side surface part gradually extends outward from the cutting insert, heading from the first end surface to the second end surface. When a second virtual plane, which is substantially perpendicular to the central axis and passes through the major cutting edge, is defined, an inwardly inclined part, on a back side of the cutting edge, of the second end surface is inclined so as to become more distant from the second virtual plane, heading from the outwardly inclined first side surface part to the central axis.
