  • Patent number: 9527142
    Abstract: A single-sided tangential ramping milling insert for high speed milling includes opposite insert seating and top surfaces and a peripheral surface which extends therebetween. The milling insert has a reference plane (P) which passes through the entire peripheral surface, midway between the seating and top surfaces. The peripheral surface includes two opposite side surfaces. Each side surface includes a first cutting edge, a second cutting edge connected to the first cutting edge and extending transversely thereto, a ramping cutting edge connected to the second cutting edge and located opposite the first cutting edge, and a rake surface which extends from at least a portion of the first cutting edge toward the insert seating surface. The milling insert includes two ramping relief surfaces, each of which extends from a ramping cutting edge of one side surface towards the first cutting edge of the opposite side surface.

  • Patent number: 9475134
    Abstract: A cutting insert has polygonal first and second end surfaces which are connected by a peripheral side surface, each end surface defining first and second end planes, respectively. The peripheral side surface has first peripheral side portions alternated in the circumferential direction with second peripheral side portions. The first peripheral side portions are inverse copies of the second peripheral side portions. Each peripheral side portion includes first and second sub-faces which form different angles with the first and second end planes. The first and second sub-faces intersect one another between the first and second end planes to form a line which is parallel to the first and second end planes.

  • Patent number: 8905683
    Abstract: A cutting tool has a cutting insert removably secured to a tool body by a fastening member. The cutting insert includes a clamping bore having at least two upper and at least two lower clamping portions intersecting a first and a second horizontal plane, respectively, the first and second horizontal planes being perpendicular to a central axis and spaced apart from each other, and the clamping bore being non-circular at cross-sections taken in the first and second horizontal planes. Upper and lower imaginary lines tangential to the at least two upper and the at least two lower clamping portions, respectively, form zero or acute first and second clamping angles with the central axis, the first and second clamping angles being different. Exactly two upper and exactly two lower clamping portions are in simultaneous clamping contact with an equal number of corresponding clamping zones on the fastening member.

  • Patent number: 8858127
    Abstract: A cutting insert has eight identical main cutting edges. Four main cutting edges can operate with a positive axial rake and four can operate with a negative axial rake. The cutting insert has two opposing identical end surfaces and a peripheral surface extending between the end surfaces. The cutting insert is square-shaped in end views. Each end surface has four corners, two lowered corners and two raised corners. A diagonal line passes through the lowered corners of each end surface. For a given orientation of the cutting insert the peripheral surface has a V-shape in views along the two diagonal lines associated with each end surface, the two V-shapes being identical in form and oriented in opposite directions.

  • Patent number: 8734712
    Abstract: A method for manufacturing a cutting insert green body from a sinterable powder, a tool set for manufacturing the cutting insert green body by that method and the green body manufactured by the tool set. The tool set has axially moving upper and lower punches and radially moving side punches. The side punches move slidably on die rods. The side punches and die rods move in channels in a base body on which a cover plate is mounted. The upper and lower punches move in through holes in the cover plate and base body, respectively. The die rods are stationary during compaction of the sinterable powder. The upper, lower and side punches form surfaces of the green body and the die rods form some of the edges of the green body. The green body can have undercuts and the edges formed by the die rods can be non-linear in shape.

  • Patent number: 8696254
    Abstract: A cutting tool has at least one cutting insert seated therein. The cutting insert has a longitudinal axis, an upper surface, a lower surface and a peripheral surface that extends between the upper surface and the lower surface. At least a portion of an intersection between the upper surface and the peripheral surface constitutes a cutting edge. The lower surface has at least one set of base abutment surfaces, each set including at a least one major base abutment surface and at least one minor base abutment surface, the major and minor base abutment surfaces of a given set being spaced apart from one another along the longitudinal axis. When the lower surface has two such sets of base abutment surfaces, the major and minor base abutment surfaces of the first set are longitudinally displaced from the corresponding major and minor base abutment surfaces of the second set.

  • Patent number: 8449223
    Abstract: An adjustment mechanism allows for bidirectional adjustment of the position of a cutting insert retained in a cutting tool by a securing screw. The adjustment mechanism includes an adjustment screw, a slider, the cutting insert and the securing screw. The rotation of the adjustment screw in opposite senses results in the bidirectional axial adjustment of the position of the cutting insert, while the securing screw is fixed in and retains the cutting insert.

  • Patent number: 8262323
    Abstract: A clamping mechanism clamps a cutting insert in a tool body. The clamping mechanism has a clamping arm seated within a clamping arm pocket. The clamping arm includes a clamping protrusion extending rearwardly from a rear surface of the clamping arm. The cutting insert has a bore having an insert retaining surface and is seated within an insert pocket. Upon tightening the clamping arm into the tool body, the clamping protrusion presses against the insert retaining surface and the cutting insert is securely abutted within the insert pocket.

  • Patent number: 8206066
    Abstract: A cutting insert for retention in a rotating cutting tool having an axis of rotation has two opposing end surfaces and a peripheral surface extending therebetween, each end surface having a mutual first axis of symmetry passing through the end surfaces about which each end surface has N-fold rotational symmetry for some value of N where N is chosen from the group consisting of 2, 3 and 4. A peripheral cutting edge is formed at the junction between each end surface and the peripheral surface, the peripheral cutting edge having N curved cutting edges merging with N straight cutting edges which extend between the curved cutting edges at extremities thereof. The curved cutting edges of the two end surfaces are not aligned in an end view of the cutting insert along the first axis of symmetry.

  • Patent number: 8202026
    Abstract: A tangential cutting insert has three pairs of surfaces. A first pair has upper and lower surfaces, a second pair has front and rear surfaces, and a third pair has two side surfaces. The upper and lower surfaces and the side surfaces extend between the front and rear surfaces. A main cutting edge is formed at the intersection of the front surface with the upper surface. A front portion of the upper surface extends rearwardly from the main cutting edge and upwardly toward a central portion of the upper surface as seen in a side view of the cutting insert. The main cutting edge associated with the upper surface is curved and slopes downwardly toward each of the auxiliary cutting edges as seen in a front view of the cutting insert.
