摘要： A two-directional high-feed turning tool assembly includes a tool holder, a cutting insert and a clamping element securing the cutting insert to the tool holder. The cutting insert includes an active cutting edge having a centrally located forwardmost edge portion and first and second main edge portions extending rearwardly from the forwardmost edge portion, as well as sideways to an extent further than flank tool sides of the tool holder. The first and second main edge portions also can each have a relatively small immersion angle facilitating high-feed turning in two sideways directions.

摘要： A method of clamping a first cutting insert or an adaptor to a holder. Either the holder includes two insert pockets configured for machining in two different orthogonal directions or the holder includes a single adaptor pocket configured for holding the adaptor in two different orthogonal directions. The method includes the steps of choosing one of two orthogonal directions for machining and securing either the first cutting insert to an appropriate one of the two pockets or securing the adaptor to the adaptor pocket for machining in the chosen orthogonal direction.

摘要： A tool adaptor has a front retaining portion and a rear mounting portion, the front retaining portion having a base jaw, a clamping jaw, and an insert receiving pocket located therebetween, and the rear mounting portion having a rear mounting surface and a first fastening bore. A primary slot separates the base jaw from the clamping jaw and communicates with the insert receiving pocket, and a secondary slot transverse to the primary slot separates the clamping jaw from the rear mounting portion. The first fastening bore has a first bore axis which intersects the rear mounting surface and the secondary slot. A cutting tool assembly includes a tool shank, and the tool adaptor secured to a front mounting portion of the tool shank by means of a first fastening screw occupying the first fastening bore and a first shank bore of the front mounting portion.

摘要： A cutting head rotatable about a head axis, has a cap portion and a mounting protuberance joined thereto and extending axially rearwardly therefrom. The mounting protuberance has a plurality of circumferentially spaced apart torque portions axially offset from a plurality of circumferentially spaced apart clamping portions. The clamping portions have clamping surfaces circumscribed by an imaginary clamping circle with a clamping diameter. The torque portions have torque protrusions and torque cut-outs, each torque protrusion having a torque transmission surface at least partially located outside an imaginary clamping cylinder defined by the imaginary clamping circle, and each torque cut-out having a recessed surface located inside the imaginary clamping cylinder. The cutting head is releasably secured to a head receiving pocket of a tool shank, with each clamping surface contacting a corresponding abutment surface of the pocket, and each torque transmission surface contacting a corresponding drive surface of the pocket.

摘要： A cutting insert has a cutting portion corner formed at the intersection of a rake surface, a forward cutting portion surface and a relief surface. A cutting edge is formed at an intersection of the rake surface and the relief surface with a land that is located on the rake surface and that extends along, and negatively away from, the cutting edge. A chip-control arrangement is located at the rake surface and includes an elongated projection and plurality of spaced apart elongated protuberances that extend from the projection to the cutting edge, so that the land has a plurality of spaced apart bulging land portions. A non-rotary cutting tool has an insert holder having an insert pocket and the cutting insert releasably retained therein.

摘要： A single-sided four-way indexable cutting insert includes a positive basic shape, a rake surface, a peripheral surface including four side abutment surfaces, a base bearing surface and a screw hole connecting the rake and base bearing surfaces. The insert has an imaginary square frustum which defines a square base containing the cutting insert's base bearing surface, and further defines four isosceles trapezoid side surfaces respectively containing the cutting insert's four side abutment surfaces. A material volume VF of the cutting insert and a void volume VS of the insert fulfill the condition VS/VF≥0.25.

摘要： A tool coupling includes a first member, having a male coupling portion extending along a first axis, and a second member, having a female coupling portion extending along a second axis. The male coupling portion has front and rear drive members defining male front and rear footprints in respective first and second transverse mating planes. The female coupling portion has front and rear drive passages defining front and rear peripheral profiles in respective first and second transverse passage planes. The front and rear drive members respectively occupy the front and rear drive passages, and at least one of the front and rear drive members prevents rotation of the second member about the second axis. On imaginary rotation of the front peripheral profile by any angle about the second axis and axial projection thereof, the front peripheral profile overlaps (i.e., at least partially crosses) the rear footprint.

摘要： A rotary milling tool has a tool holder and a milling head releasably attached thereto. The milling head has a plurality of angularly spaced apart peripherally disposed cutting edges which form an effective cutting edge. The milling head has a head through recess opening out to the head forward and rearward surfaces. The recess includes a centering region and a driven region, the driven region being axially forward of, and non-identical to, the centering region. The driven region has at least one driven surface facing opposite a rotational direction. The centering region has at least one radially inwardly facing radial centering surface located axially rearward of, and radially outward from, the at least one driven surface. The two opposing extremities of the effective cutting edge define two parallel planes respectively between which both the at least one driven surface and the at least one radial centering surface are disposed.

摘要： A swiss turning tool assembly includes an insert and a tool holder. The tool holder includes a head portion which in turn includes an insert pocket and a fastener hole opening out to a flank side of the tool and to a pocket opening in the insert pocket. The insert pocket also includes a tool clamping arrangement which in turn includes a tool base surface and at least one tool abutment surface forming an external acute angle with the tool base surface. The insert includes an insert base surface which in turn includes at least one insert abutment surface forming an internal acute angle with the insert base surface. To achieve a clamped position, a single fastener, accessed from the tool's flank side abuts the insert.

摘要： A cutting tool has a cutting body with a first insert pocket and an indexable cutting insert removably mounted therein. The first insert pocket has a first seat surface with a plurality of first engagement elements and a first support wall transverse thereto. The cutting insert has upper and lower surfaces and a boundary surface extending therebetween. The lower surface has a plurality of lower engaging elements and the boundary surface has a plurality of alternating first and second peripheral surfaces intersecting the upper surface to form first and second upper cutting edges. In each index position with the lower surface in contact with the first seat surface, the first support wall prevents translation of the cutting insert in a first direction, and the first engagement elements eccentrically contact the lower engaging elements to prevent translation of the cutting insert in a second direction perpendicular to the first direction.
