    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.

    摘要： A double-sided cutting insert includes two end surfaces that each includes major rake surfaces adjacent major cutting edges that form first angles with planes of major side surfaces of the insert, and a central support surface forming a second angle with the planes of the major side surfaces. Each end surface further includes major intermediate surfaces between the major rake surfaces and the central support surface. The major intermediate surfaces form third angles with the planes of the major side surfaces that are greater than the first angles and smaller than the second armies when measured in a central plane that extends along a central axis of the hole and is generally perpendicular to the planes of the major side surfaces and planes of the central support surfaces.

    摘要： The invention relates to a cutting matrix (10) to be tighten in a cutting tool (14) used for cutting cast materials. The inventive cutting matrix comprises a top surface (13), a first cavity for tightening (11) in the cutting tool (14) and a cutting edge for cutting by stock removal. The aim of the invention is do not modify the tightening characteristics of the cutting matrix (10) by honing or grinding the top surface (13) thereof. For these purposes, a second tightening cavity (12) is arranged coaxially with respect to the first cavity (11). Said first cavity (11) is embodied such that it is deeper than the second tightening cavity (12), both cavities being arranged more deeply with respect to the upper surface (13) of said cutting matrix.

    摘要： The present invention relates to a cutting insert, a cutting tool for chip removing machining, a shim as well as a method for mounting a cutting insert. The cutting tool comprises a holder (31) equipped with at least one insert pocket (32) including a base surface (33), at least one circular shim (21) including opposite first and second surfaces, and at least one cutting insert (10), which comprises a circular cutting edge (14) formed at a transition between an upper side (11) and an edge surface (13) of the cutting insert. The upper side (11) comprises a chip surface comprising at least one chip breaker portion (18) and said edge surface constitutes a clearance surface. The shim (21) is provided between the base surface (33) of the insert pocket and the cutting insert (10). The cutting tool (30) comprises means for holding its parts together. The chip breaker portion (18) is provided at varying distance from the associated cutting edge (14). The shim (21) and the cutting insert (10) comprise at least one pair of cooperating projection and recess for indexing of the cutting insert. Said pair of cooperating projection and recess is provided to be positioned in a position relative to a reference line or axis of the tool (CL2) in order to orient the chip breaker portion (18) in the chip surface to a desired relative position. The number of chip breaker portions (18A-18E) is a multiple of the number of projections or recesses (20A-20E).
