摘要： A cutting insert for grooving operations includes a central shank portion and a forward cutting head. The cutting head includes a front clearance surface having a main cutting edge at an upper end thereof. The clearance surface is non-planar. Rather, the clearance surface exhibits a curvature in order to strengthen the main cutting edge.

摘要： A cutting insert is clamped in a pocket of a holder by a top clamp assembly which includes a clamp arm screwed to the holder, and a clamp plate interposed between the insert and a front part of the clamp arm. The clamp plate is formed of a harder and more wear-resistant material than the clamp arm and transmits clamping forces from the clamp arm to the cutting insert. The hard clamp plate shields the clamp arm from being impacted by chips generated during a machining operation, thereby minimizing wearing of the clamp arm.

摘要： A metal cutting tool includes a holder arrangement, an indexible cutting insert seated on an insert-receiving site of the holder arrangement, and a screw for fastening the insert to the site. The bottom side of the insert includes more than two upright abutment surfaces arranged to abut respective upright support surfaces of the site, whereby the areas of contact formed by the mutually abutting surfaces lie inside of an outer perimeter of the insert. The abutment surfaces are oriented non-parallel to one another. The screw is arranged to urge the insert in a direction whereby less than all of the abutment surfaces abut respective support surfaces, and at least one abutment surface does not abut a support surface. When the insert is indexed, the non-abutting abutment surface is relocated and caused to abut a support surface when the screw is tightened, while an abutment surface that previously abutted a support surface becomes a non-abutting surface.

摘要： A metal-cutting tool comprises a holder, a clamp, and a metal-cutting insert. The holder includes a blade part which forms an upwardly facing seating surface extending in a front-to-rear direction. The holder includes a recess including a longitudinal axis extending in the front-to-rear direction at an angle relative to the seating surface, whereby an imaginary rearward extension of the seating surface converges toward the axis. The insert is mounted on the seating surface and the clamp has a rear portion which is slidable within the recess, whereby a front portion of the clamp pushes downwardly and rearwardly against a top surface of the insert. That top surface is shaped so that the front portion of the clamp is flexed upwardly relative to the rear portion when the rear portion is pushed rearwardly to the clamping position.

摘要： Reaming tool includes a head and a detachable cutting insert fixed in a seat. The seat includes radial, tangential, and axial support surfaces, while the cutting insert has a mirror-symmetrical polyhedron shape comprising six limiting surfaces, viz. two chip surfaces and at least two clearance surfaces, a number of alternately usable, identical cutting edges formed in transitions between the chip and clearance surfaces. A female- or male-like securing means co-operates with a complementary, male- or female-like securing means in the seat, more precisely in an inactive, contactless state as long as the cutting insert is held pressed by the cutting forces against the axial support surface. The securing means is activatable when the cutting insert is unintentionally distanced from the axial support surface against the action of a clamping member. Tool head and reaming insert for the tool are disclosed.
