Description

Die Neuerung betrifft einen Drehmeißel mit um eine waagerechte Achse drehbarer Vielfachschneidplatte.The innovation relates to a turning tool with a multiple cutting insert that can be rotated about a horizontal axis.

Die bekannten Schneidplatten dieser Art sind als Abstechmeißel nicht geeignet, weil sie sich unter dem hohen Arbeitsdruck wegdrehen.The known cutting inserts of this type are not suitable as parting chisels because they are subject to the high working pressure turn away.

Der Neuerung liegt die Aufgabe zugrunde, diesen Nachteil auf einfache Weise zu beseitigen.The innovation is based on the task of eliminating this disadvantage in a simple manner.

Die Neuerung besteht darin, daß die Vielfachschneidplatte durch einen dreiarmigen Stern ersetzt ist, der an dem Schaft satt aufliegt und an seinen Enden Hartmetallplatten trägt.The innovation is that the multiple cutting insert is replaced by a three-armed star that is attached to the shank rests snugly and carries hard metal plates at its ends.

Die Zeichnung gibt einen Drehmeißel nach der Neuerung mit einer Schneidplatte in Form eines dreiarmigen Sternes beispielsweise wieder, und zwar zeigt:The drawing shows a lathe chisel according to the innovation with a cutting plate in the form of a three-armed star, for example again, namely shows:
