摘要： The invention relates to a polygonal indexable insert which comprises cutting edges (2) which extend in a straight or curved manner on a plane which is perpendicular to the bearing surface, said cutting edges tilting from cutting corners (3) at an acute angle to alternating successive cutting edges (4) at an obtuse angle. The cutting edges (2) have an initially tiling cutting face (6) which mounts with a rear area (7). The rear area (7) forms an intersection curve (8) with a centre part (18) of the indexable insert. The intersection curve (8) has a space (a) from the starting point (15) of the associated cutting edge (2) in the region of the cutting corners (3), respectively, in the intersection point (9) with the bisecting line (10), and a space (b) from the end point (16) of the associated cutting edge (2), which is greater than the space (a), in the region of the cutting corners (4) in the intersection point thereof (11) with the bisecting line (12).

摘要： Die Erfindung betrifft eine Anordnung und eine Befestigung von Schneidplatten, für Schneidwerkzeuge.
Aufgabe der Erfindung ist es eine Anordnung und eine Befestigung von Schneidplatten zu entwickeln, die selbst für Werkzeuge mit großen Schneidenlängen geeignet ist, dabei eine optimale schnelle und gleichzeitig fertigungstechnisch einfache Verspannung der Schneidplatte mit dem Werkzeuggrundkörper ermöglicht und zudem die durch den Schneid- bzw. Zerspanungsprozess bedingten Schwingungen deutlich reduziert und gleichzeitig die Lebensdauer der Schneidplatte insgesamt wie auch die auf die Schneidenlänge bezogene Standzeit deutlich erhöht sowie die Herstellungs- und Instandhaltungskosten der Schneidwerkzeuge merklich senkt.
Erfindungsgemäß wird diese Aufgabe dadurch gelöst, dass die am Werkzeuggrundkörper (2) angeordnete/n Werkzeugschneide/n (5) jeweils von den Schneiden (6) mehrerer, nebeneinander auf einer gemeinsamen Auflagefläche (9) des Werkzeuggrundkörpers (2) angeordneten, Schneidplatten (1) gebildet wird/werden, wobei parallel zur Schneide (6), im Bereich der Befestigungsbohrung (19), in der Bodenfläche (7) jeder Schneidplatte (1) jeweils eine Nut (8) bzw. beidseitig der Befestigungsbohrung (19) am Rand der Schneidplatte (1) Nutsegmente (8A) angeordnet ist/sind, und am Werkzeuggrundkörper (2) auf der zugeordneten gemeinsamen Auflagefläche (9) der Schneidplatte/n (1) eine der Nut (8) / den Nutsegmenten (8A) zugeordnete, in ihrer Breite / Tiefe und Höhe gegenüber der Nutbreite / Nuttiefe und Nuthöhe der Schneidplatte/n (1) jedoch ein Arbeitsspiel aufweisende Führungsschiene (10) bzw. Führungsschienenabschnitte (10A) angeordnet ist / sind.摘要翻译： 工件工具刀片（5）由几个切割板（1）的刀片（6）形成。 在紧固孔附近的每个切割板的基面上设有凹槽。 对于板的铺设表面，放置足够的呼吸和深度相对于槽宽度和深度以允许发挥运动的导轨。 在槽的帮助下，切割板沿着导轨张紧。

摘要： A cutting insert intended for chip removing machining is delimited by a top side (2), a bottom side (3) and a number of side surfaces (4) extending between these sides. The cutting insert has a cutting edge (5) between said top side (2) and a side surface serving as a flank. Grooves (8) which are mutually separated are provided in the top side of the cutting insert (2), in connection with this cutting edge, for feeding the cooling liquid in the direction towards the cutting edge. Projections (9) are arranged between adjacent grooves (8), which protrude from the top side of the cutting insert and which together form a chip deflector for every chip cut free by the cutting edge.

摘要： Proposed is a drilling tool for drilling in solid material, having a base body (1) containing chip flutes (5, 5a) and at least two interchangeable inserts (3, 3a) situated in a recess (4, 4a) at the end of a chip flute (5, 5a) at the face of the base body (1). The inserts are arranged on the base body at different radial distances such that their working ranges partially overlap. The blades (12) of the inserts (3, 3a) are formed by two cutting edges (8, 9) which together form an obtuse angle, that is the point angle (11). The face (13) of the blades (12) has parallel profile ribs (14, 14a) which acts as runners and which in the region of the cutting edges (8, 9), aligned approximately normal to them, run out from there roughly in the direction of chip removal, radially inwards over a curved course relative to their fitting position, toward a flank region (17) of the insert (3, 3a) near the drilling tool axis (7).

摘要： The invention concerns a cutting insert for machining workpieces (preferably of metal) while removing the cuttings. The cutting insert in question is provided with at least one cutting edge (10) in the transition region between a rake (16) and a flank (18); the rake (16) comprises a flat face section (20) which is substantially parallel to the cutting edge (10) and several dome-shaped recesses aligned in a row and separated by gaps, said recesses being parallel to the cutting edge (10), moulded into the face section (20) and partially penetrating the cutting edge (10). To ensure the uninterrupted removal of cuttings when short cuttings are produced, the invention proposes that a cutting form step (24) is provided on the face of the recesses opposite to the cutting edge (10); said cutting form step rises above the face section and is bounded by a bottom boundary line (26) on the cutting edge side and by a top boundary line (28) on the side away from the cutting edge.
