摘要： A turning and face grooving tool body has a pocket and a pin. The pin has a unitary one-piece construction and an elongated shape which defines a longitudinal direction along a pin axis. The pin includes pin top and bottom ends, a pin peripheral surface which extends therebetween, and a pivot protrusion which extends outwardly from the pin peripheral surface. The pin is rotationally asymmetric about the longitudinal pin axis. The pocket includes a base surface, transverse support walls, and a pin bore which opens out to the base surface and includes a pin bore inner surface. The pin is located in the pin bore and the pin top end protrudes beyond the base surface. The pivot protrusion is spaced apart from the pin top and bottom ends, offset in the longitudinal direction from a pin midway-point which is located midway between the pin top and bottom ends.

摘要： A cutting tool (20) includes a two-way indexable cutting insert (22) clamped in a transversely oriented insert receiving pocket (46) of an insert holder (24). The insert holder (24) includes a forwardly located insert mounting portion (32) that includes upper and lower jaws (34, 36) which together define the insert receiving pocket (46) having a pocket front opening (52a). The lower jaw (36) includes a pocket lower clamping surface (54). The upper jaw (34) includes a pocket upper clamping surface (60) which faces mutually towards the pocket lower clamping surface (54) and a pocket stopper surface (68) facing generally towards the pocket front opening (52a). The pocket stopper surface (68) is closer to the pocket lower clamping surface (54) and further from the pocket front opening (52a), than the pocket upper clamping surface (60). The pocket stopper surface (68) is further from the pocket rear opening (52b) than the pocket lower clamping surface (54).

摘要： A slitting tool (10) configured for fine-tuning thereof includes basic body (12), which in turn includes a body portion (18) and a cutting portion (20) extending therefrom. The slitting tool (10) includes a biasing screw (14) which is seated in a biasing bore (54) and is configured to adjust the position of the cutting portion (20). The biasing screw (14) is configured to engage a biasing surface (86) of the body portion to adjust the cutting portion's (20) position. The biasing surface (86) is oblique relative to the biasing screw (14) for retarding movement of the biasing screw (14) a fine-tuned position.

摘要： A slitting cutter (20) having a disk-shaped cutter body (22) with a plurality of circumferentially spaced insert receiving portions (28) and a plurality of cutting inserts (30) retained therein. Each insert receiving portion has first and second clamping jaws (32, 34) spaced apart by an insert receiving slot (36), the first clamping jaw resiliently displaceable and having a resilient axis of rotation (AR). The number of cutting inserts resiliently clamped in the slitting cutter is an inner cutting diameter (Dl) defined by the plurality of resilient axes of rotation multiplied by a spacing factor of between 0.15 and 0.30. A tool key having first and second key prongs is used in combination with the slitting cutter. The second key prong has a thrust surface with a concave profile. In a partially assembled position of the slitting cutter the thrust surface contacts at least one of two spaced apart first and second corner surfaces of the respective cutting insert.

摘要： A blade-shaped cutting insert (20) has opposing first and second insert side surfaces (22a, 22b) with a peripheral surface (24) extending therebetween, and a first cutting portion (34a) having a first primary cutting edge (36a) extending between the first and second insert side surfaces, defining a maximum insert width of the cutting insert. The peripheral surface includes an upper surface (28) and first and second diverging flank surfaces (26a, 26b) bisected by a first plane transverse to the upper surface. The cutting insert has a maximum insert length measured perpendicular to the first plane which is more than sixteen times greater than the maximum insert width, and a maximum insert height measured parallel to the first plane which is more than ten times greater than the maximum insert width. The cutting insert is removably secured in an insert receiving pocket of a tool holder, which is defined by an upper clamping jaw and a lower clamping jaw.

摘要： A non-indexable, one-sided cutting insert (18, 118) includes opposite insert side surfaces (20) which define an insert width (IW) therebetween, opposite insert front and rear surfaces (22, 24, 124) which extend between the insert side surfaces (20) and define an insert depth (ID) therebetween and opposite insert top and bottom surfaces (26, 126, 28) which extend between the insert side surfaces (20) and the insert front and rear surfaces (22, 24, 124). The insert top and bottom surfaces (26, 126, 28) define an insert height (IH) therebetween. The insert (18, 118) further includes a main cutting edge (34) formed at an intersection between the insert top and front surfaces (26, 126, 22). A maximum value of the insert width (IW) is smaller than a minimum value of the insert height (IH) and smaller than a minimum value of the insert depth (ID). The insert includes a deep opening (44) which opens out only to the insert bottom surface (28) and defines an opening depth (OD). A depth ratio defined between the opening depth (OD) and the insert height (IH) is greater than 0.3.

摘要： A cutting tool having a tool holder, cutting insert and clamping member. The tool holder includes an elongated supporting surface extending in a rearward-to-forward direction. The cutting insert has a central portion and three cutting portions, the central portion having two opposing side surfaces and three spaced apart locating surfaces defining a first imaginary triangle. The cutting insert is indexable about a central axis intersecting the two side surfaces. Each locating surface intersects two of three bisector planes containing the central axis and bisecting respective corners of the first imaginary triangle, and the cutting edge of each cutting portion is located entirely outside of the first imaginary triangle. In each index position the clamping member is located entirely rearward of a first vertical plane containing the central axis and perpendicular to the rearward-to-forward direction, and one of the locating surfaces is in clamping contact with the supporting surface.
