33er Im euer ling liegt die Ausgabe z-agrunae ein Werizeug der eten angeführten Art zu schaffen, daß sich ohne Äus^echslxuig irgendwelcher 2eile in gleicher Weise zxan. Abnehmen grober, iDei großen Vorschuhen entstehender Späne und feiner, "bei kleinen Vorschüben gebildeter Späne eignet. Gemäß der1 Neuerung v/ira dies dadurch erreicht, daß sich einerseits ., wie an sich bekannt, zwischen Kleismpratze und festgeklemmter Schneidplatte eine schräge, zur Ablenkung grober Späne dienende Fläche aufweisende Spanformplatte befindet und daß andererseits , wie ebenfalls an sich bekannt, nahe der Schneide eine zur formung feiner Schlichtspäne dienende Spanformnut vorgesehen iste Die feuerung basiert aomit auf der überraschenden Peststellung, daß grobe Späne ohne weiters über die zur formung feiner Schlichtspäne dienende- Spanformnut gleiten und erst durch die schräge ?iäche der Spanform— platte abgelerkt werden.33er In your ling lies the edition z-agrunae a tool of the kind mentioned to create that zxan in the same way without utterance of any kind. Removal of coarse chips that arise in large foreshoes and of fine chips that are formed with small feeds. According to the first innovation, this is achieved on the one hand, as is known per se, between the glue claw and the clamped cutting plate for an inclined deflection The chipboard, which is used for coarse chips, is located, and on the other hand, as is also known per se, a chip-forming groove serving to form fine finishing chips is provided near the cutting edge - Slide the chip-forming groove and only be marked through the inclined surface of the chip-forming insert.
