摘要： A cutting tool includes a replaceable cutting insert and a tool body. The tool body includes a tool body surface and an insert pocket recessed therein. The cutting insert is releasably retained in the insert pocket. The tool body includes at least one coolant duct that has an outlet orifice that opens out in a coolant chamber. The coolant chamber is bounded on a side opposite the outlet orifice by a coolant deflection portion that is integrally formed with the tool body in a unitary one-piece construction and at least partially overhangs the outlet orifice in a direction towards the insert pocket. The coolant deflection portion has a chamber deflection surface configured to deflect a coolant in the direction of a cutting edge of a cutting insert seated in insert pocket.

摘要： A non-indexable, one-sided cutting insert includes opposite insert side surfaces which define an insert width therebetween, opposite insert front and rear surfaces which extend between the insert side surfaces and define an insert depth therebetween and opposite insert top and bottom surfaces which extend between the insert side surfaces and the insert front and rear surfaces. The insert top and bottom surfaces define an insert height therebetween. The insert further includes a main cutting edge formed at an intersection between the insert top and front surfaces. A maximum value of the insert width is smaller than minimum value of the insert height, and a minimum value of the insert depth. The insert includes a deep opening which opens out only to the insert bottom surface and defines an opening depth. A depth ratio defined between the opening depth and the insert height is greater than 0.3.

摘要： A replaceable cutting head includes a forward cutting portion and a rearward mounting portion. The mounting portion includes a male coupling member that protrudes rearwardly from a head base surface. The male coupling member includes forward and rearward bearing portions and an external thread located therebetween. The forward and rearward bearing portions include respective conically shaped forward and rearward head abutment surface. The forward and rearward head abutment surfaces have the same cone angle. When a cutting tool, including said cutting head and a tool holder having a female coupling member, is in a locked position, the external thread is threadingly engaged in the female coupling member and the forward and rearward head abutment surfaces conically abut corresponding conical shaped surfaces in the female coupling member.

摘要： A tool holder has a main body with a holder head extending away from a holder shank, the holder head having an insert receiving pocket at a forward end thereof, with a pocket support surface. A clamping member is retained in the holder head, the clamping member comprising a clamping shaft longitudinally extending along a shaft axis. A locking member operatively engages an abutment surface of the clamping shaft. The shaft axis does not intersect the pocket support surface, and the clamping shaft has a non-circular shape in a cross-section taken perpendicular to the shaft axis. The tool holder is configured to direct a clamping force towards, and clamp a cutting insert against, the pocket support surface.

摘要： A cutting tool assembly includes a cutting tool and an indexable cutting insert having an insert index axis. The cutting insert includes parallel insert first and second sides connected by an insert peripheral surface that extends peripherally around the cutting insert. At least one clamping hole opens out to one or both of the insert first and second sides, and at least a portion of the clamping hole is in a clamping region of the cutting insert. The insert peripheral surface includes cutting edges that are spaced-apart and extend from the insert first side to the insert second side. Along a width direction, which is perpendicular to the insert first and second sides, each of the cutting edges is wider than the cutting insert, at least at the cutting region of the cutting insert.

摘要： A compact oldham-type floating reamer holder with holder and reamer portions which transfer torque therebetween via a floating member. The floating reamer holder includes an elastic element which axially biases the holder and reamer portions. In an operative position, the floating reamer holder is configured to automatically enable angular misalignment, parallel misalignment and axial translation between the holder and reamer portion axes. In a non-operative position, the reamer portion axis is co-aligned with the holder portion axis. And the elastic element at least partially overlaps the reamer portion.

摘要： In a rotary cutting tool used for milling operations, a reversible cutting insert is removably secured in a cutting body. The cutting insert has two opposing end surfaces interconnected by a continuous peripheral surface, which includes three side surfaces alternating with three corner surfaces. The side and corner surfaces intersect with both end surfaces at side and corner edges, respectively, with each side edge having a major cutting edge, and each corner edge having a corner and minor cutting edge. Each minor cutting edge has a projected minor cutting length, in an end view, and each associated minor relief surface has a minor relief width between two lateral boundary points contained in a horizontal plane, varying with an offset distance between the horizontal plane and a median plane. Each projected minor cutting length is greater than the maximum minor relief width of its associated minor relief surface.

摘要： A cutting insert having two end surfaces and a peripheral surface, the end surfaces located on opposite sides of a mid-plane, each end surface having three primary apexes and three secondary apexes. Six cutting portions are formed along the intersection of the peripheral surface and the end surfaces. Each cutting portion has a first cutting edge and a second cutting edge extending transversely thereto. A ramping cutting edge extends between the second cutting edge of each cutting portion and the first cutting edge of an adjacent cutting portion. The peripheral surface has a clearance surface extending from each of the second cutting edges towards the mid-plane. The abutment planes of the insert are parallel to the mid-plane. Each of the first cutting edges lies between an adjacent abutment plane and adjacent primary apex.
