  • Patent number: 9676044
    Abstract: A cutting tool and cutter body assembly, including a disk-shaped cutter body and a plurality of support pads removably retained therein, the cutter body having an axis of rotation, two opposing end surfaces and a body peripheral surface extending therebetween. Each support pad intersects one of two annular-shaped planes equidistantly offset from opposite sides of a median plane perpendicular to the axis of rotation, and the cutter body intersects neither of the two annular-shaped planes. Each support pad is configured to make operative contact with a machined surface of a workpiece perpendicular to the axis of rotation. Each support pad has opposing upper and lower surfaces and a pad peripheral surface extending therebetween, the pad peripheral surface having an upper portion intersecting the upper surface, and the upper portion exhibiting N-fold rotational symmetry about a pad axis non-perpendicular to the lower surface.

  • Patent number: 9259789
    Abstract: An indexable cutting insert has two cutting protrusions extending from opposite end surfaces towards a mid plane. Each cutting protrusion has a rear surface, an oppositely facing rake surface, a relief surface. A main cutting edge is formed at the intersection of the rake and relief surfaces, and extends between two main cutting edge ends. An edge projection is formed by a line connecting longitudinal projections of the main cutting edge ends of each main cutting edge. The edge projections of both of the main cutting edges form a non-zero first angle therebetween. The rake surfaces of the cutting protrusions are located on longitudinally opposite end surfaces of the cutting insert. Two clamping recesses and two abutment recesses serve as contact surfaces for clamping the cutting insert in an insert pocket of a cutting tool.

  • 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.

  • Patent number: 7097393
    Abstract: A tangential cutting insert having first and second opposing end surfaces and a peripheral side surface extending therebetween. First and second edges are formed at the intersection of the first and second end surfaces with the peripheral side surface. A groove in the peripheral side surface extends between and intersects the first and second end surfaces at first and second minor edges. In first and second opposing side views of the cutting insert, at least the first edge is generally concave.

  • Patent number: 7008147
    Abstract: A rectangular blade-type cutting tool having two edge-on cutting inserts mounted at one end of the blade in a staggered formation with their cutting edges partially overlapping. This type of cutting blade finds particular application in disc-type cutting tool assemblies used for cutting pipes. In such a cutting tool assembly the blade-type cutting tools in accordance with the present invention are equally peripherally distributed on an end face of the cutting tool assembly with the operative cutting edges of each of cutting blade inwardly directed and equally distanced with respect to the axis of rotation of the cutting tool assembly. With such a cutting tool assembly it is only necessary to cut the thickness of a pipe without the necessity of passing across its entire diameter allowing for quick and economical cutting of the pipe.
