A cutting tool has a plurality of cutting portions located along a cutter peripheral surface, alternating between cutter side surfaces, with a cutting insert retained in each cutting portion. At least one cutting portion has a main recess, formed opposite of the respective cutting insert. The main recess has a recess arcuate surface and a recess bearing surface. The cutting portion also has a cam member with a cam arcuate surface and a cam bearing surface, located on different sides of a cam pivot axis. The cam member is located within the main recess, the cam arcuate surface being adjacent the recess arcuate surface and the cam bearing surface being adjacent the recess bearing surface. The cutting portion is moveable between a neutral position and an adjusted position, in which the axial position of the cutting insert is adjusted when the cam member is rotated about the cam pivot axis. |

1. A cutting tool (100) having an axis of rotation (R) and comprising:
a cutter body (102), having two cutter side surfaces (104) and a cutter peripheral surface (106) extending therebetween; a plurality of circumferentially spaced apart cutting portions (108) located along the cutter peripheral surface (106), each cutting portion (108) comprising an insert pocket (110) for retaining a cutting insert (112), the insert pockets (110) of two adjacent cutting portions (108) being formed alternately on different cutter side surfaces (104); wherein at least one cutting portion (108) comprises:
a main recess (114), formed on the cutter side surface (104) opposite of the respective insert pocket (110), and having a recess arcuate surface (116) and a recess bearing surface (118) located across from the recess arcuate surface (116); andan axial position adjustment arrangement (122), comprising a cam member (124) having a cam arcuate surface (126) and a cam bearing surface (128), located on different sides of a cam pivot axis (P), the cam member (124) being located within the main recess (114) with the cam arcuate surface (126) adjacent the recess arcuate surface (116) and the cam bearing surface (128) adjacent the recess bearing surface (118); and wherein the at least one cutting portion (108) is moveable between a neutral position and an adjusted position, and in the adjusted position of one of the at least one cutting portion (108), the axial position of the cutting insert (112) is adjusted when the cam member (124) is rotated about the cam pivot axis (P) in a first direction (D). |
