    摘要： The invention concerns a holder for metal-cutting tools, in particular piercing or cutting tools. The holder has a clamp in which the tool is held, the two jaws of the clamp having between them a slot into which a key with an elliptical or oval cross-section can be inserted and turned to open the jaws. In order to ensure that, while the jaws are being opened, the key remains securely in position without slipping, the invention proposes that the slot (25) has, located on opposite sides, part-circular enlargements (13, 14) whose vertices are a distance (e) apart which is smaller than the greatest distance (a) across the elliptical or oval cross-section (15) of the key.

    摘要： Disclosed is a cutter insert for machining workpieces, the insert having a front cutting edge (15) disposed at right angles to the longitudinal axis (25) of the insert, a central concave chip-forming depression (23) delimited at each side by chamfers (21, 22) to protect the cutting face. Behind each of the chamfers (21, 22), facing towards the chip-forming depression (23) and extending out into the depression, are nose-like chip-forming elements (24) which are disposed symmetrically with respect to the longitudinal axis (25) of the insert and which abruptly narrow the bottom face of the chip-forming depression, preferably non-continuously, in the chip-runoff direction.

    摘要： A metal cutting tool assembly comprising a rigid holder blade (1), an insert receiving slot (9) formed in a leading end of the holder blade and defined between a resiliently displaceable clamping jaw (3) formed integrally with the holder blade (1) and rigid base jaw (4) forming part of the holder blade, spaced apart displacement and supporting surfaces respectively formed in or on the clamping jaw (3) and the holder, and a slot opening key (21,33,41) a pair of spaced apart projecting prongs (24a,24b/34a,34b/42a,42b) of the key adapted to engage the surfaces. At least one of the prongs is displaceable with respect to the holder blade so as resiliently to displace the clamping jaw (3) outwardly with respect to the base jaw into an opening position for insertion or removal of an insert (7).

    摘要： An improved cutting insert with chip control features and a method for manufacturing the same. An insert body having wall regions, sides and top and bottom walls is adapted for mounting in a pocket in a holder. The insert body has cutting edges and a diagonal notch in the top and bottom sides. A land region extends rearwardly from the end wall region toward the respective top or bottom wall and defines a surface region of a predetermined width. A descending wall initiates in a portion of the land and terminates in a planar floor region having a forward, a rearward and opposed side edges. A back ramp extends upwardly from the planar floor rearward edge and terminates at the respective top or bottom wall. The end wall region can include at least one flat land region adjacent the land region. The flat land region defines a selectively removable portion of the end wall region and after any selective removal thereof represents no more than approximately one-third of the total width of the end wall region.

    摘要： A parting and/or grooving tool includes a support blade (10) and a cutting insert (12) removably securable in a recess (11) formed by upper and lower jaws (10a, 10b) at the front portion of the blade. The insert is clamped into place by a screw (23) which engages in a slot (19) that extends at an angle in relation to the longitudinal axis of the recess (11) such that the upper jaw (10a) is subjected to an elastic bending of such nature that a downwardly directed clamping force is exerted towards the upper surface of the cutting insert (12).
