Schneidplättchen für die EndbearbeitungCutting tips for finishing
Die Erfindung bezieht sich auf ein auswechselbaresThe invention relates to an interchangeable
Schneidplättchen aus Hartmetall bzw. mit Hartmetallbestückung. Dieses Schneidplättchen kann alle möglichen geometrischen Formen aufweisen und z. B. viereckig, dreieckig usw. ausgebildet sein.Cutting tips made of hard metal or with hard metal tipping. This cutting tip can do all kinds of things have geometric shapes and z. B. square, triangular, etc. be formed.
Dieses Schneidplättchen wird insbesondere für die Endbearbeitung mit der Möglichkeit angewendet, das Material mit mittleren Spandicken abzuheben.This cutting tip is used in particular for finishing with the possibility of using the material medium chip thicknesses.
Bei der Verwendung üblicher Schneidplättchen trifft man ziemlich schnell auf einen Widerstand gegen den Schnitt, wenn die Spandicke gering ist. Dies zieht eine mangelnde Planheit und eine mangelnde Qualität der Oberfläche des bearbeiteten Werkstückes nach sich.When using conventional cutting tips, resistance to the cut is encountered fairly quickly if the chip thickness is small. This draws a lack of flatness and a poor quality of the surface of the machined Workpiece after itself.
Die vorliegende Erfindung versucht diese Nachteile dadurch zu beseitigen, daß das Schneidplättchen mit Spanbrechern konvexThe present invention seeks to overcome these disadvantages by making the cutting tip convex with chip breakers

ausgebildete Hauptschneiden aufweist, die an ihren beiden Enden in Vertiefungen enden, die durch den Auslauf der angrenzenden Spanbrecher gebildet sind.has formed main cutting edges, which end at both ends in depressions, which through the outlet of the adjacent Chip breakers are formed.
Die beigefügte zeichnung zeigt in schematischer Form ein Ausführungsbeispiel eines Schneidplättchens nach der Erfindung.The attached drawing shows in schematic form a Embodiment of a cutting tip according to the invention.
Fig. 1 ist eine Seitenansicht eines Schneidplättchens,Fig. 1 is a side view of a cutting tip,
Fig. 2 eine Ansicht von oben auf dieses Schneidplättchen undFig. 2 is a view from above of this cutting tip and
Fig. 3 einen Teilschnitt nach der Linie A-A.Fig. 3 is a partial section along the line A-A.
Das Schneidplättchen 1 hat beispielsweise eine dreieckige Form, dessen Ecken 2 abgerundet sind und dessen Seiten 3 gegebenenfalls um einen Betrag zwischen 0 und 25° hinterschnitten sind.The cutting tip 1 has, for example, a triangular shape, the corners 2 of which are rounded and the sides 3 of which, if applicable are undercut by an amount between 0 and 25 °.
Die obere Fläche 4 kann eben sein.The upper surface 4 can be flat.
Die Spanbrecher bzw. Spanleitstufen 5, 6, 7 sind parallel zu den Schneiden des Schneidplättchens bearbeitet.The chip breakers or chip breakers 5, 6, 7 are parallel machined to the cutting edge of the cutting tip.
Die Hauptschneiden 8, 9 und 10 sind konvex entsprechend einem Kreisbogen ausgebildet.The main cutting edges 8, 9 and 10 are convex, corresponding to an arc of a circle.
Der Spanbrecher 5 verläuft parallel zur Schneide 8 und schneidet die Schneiden 9 und 10.The chip breaker 5 runs parallel to the cutting edge 8 and cuts cutting edges 9 and 10.
Der Spanbrecher 6 ist parallel zur Schneide 9 und schneidet die Schneiden 8 und 10.The chip breaker 6 is parallel to the cutting edge 9 and cuts cutting edges 8 and 10.
Der Spanbrecher 7 ist parallel zur Schneide 10 und schneidet die Schneiden 8 und 9.The chip breaker 7 is parallel to the cutting edge 10 and cuts the cutting edges 8 and 9.

Diese neue Geometrie des Schneidplattchens gestattet einen besonders feinen Schnitt zu erhalten. Sie erleichtert in besonderem Maße die Endbearbeitung bei der Planbearbeitung, beim Ausdrehen und bei anderen Bearbeitun.^svorgängen aufgrund des positiven, weichen und fortlaufenden (progressiven) Schnittes. Diese Geometrie schützt die Schneide ohne den Schnitt zu beeinträchtigen. Diese Tatsache verlängert die Lebensdauer der Schneide und gestattet dünnwandige Werkstücke aufgrund der Verminderung der Schwingungen zu bearbeiten. This new geometry of the cutting insert allows a particularly fine cut to be obtained. She relieved in particular the final processing in plan processing, in boring and in other processing operations due to the positive, soft and continuous (progressive) cut. This geometry protects the cutting edge without affecting the cut. This fact extends the service life of the cutting edge and allows thin-walled workpieces to edit due to the reduction in vibrations.
Dieses Schneidplättchen gestattet nach links oder nach rechts und im Falle des Präsens nach vorn oder nach hinten zu arbeiten. Die Qualität der Oberfläche ist ausgezeichnet und die Einstellung erfordert weniger Sorgfalt als bei einem Schlichtplättchen mit Planphasen (ebenen Flächen).This cutting plate allows to the left or to the right and in the case of the present tense to the front or back to work. The quality of the finish is excellent and the adjustment requires less care than one Finishing platelets with plane phases (flat surfaces).
Die Form der Spitze macht die Schneide sehr scharf. Diese Spitze ist weniger beansprucht als bei einem geschlossenen Spanbrecher.The shape of the tip makes the cutting edge very sharp. This tip is less stressed than with a closed one Chip breaker.
Der erhaltene Span weist eine gute Spiralform auf, er klebt weniger an der Schneide und wird leicht abgeworfen.The chip obtained has a good spiral shape, it sticks less to the cutting edge and is easily thrown off.
Dieses Schneidplättchen bearbeitet in besonders günstiger Weise alle üblichen Werkstoffe sowie normalen Flußstahl und Aluminium.This cutting tip processes all common materials and normal mild steel in a particularly favorable manner Aluminum.
