VERWENDUNG VON ZERSPANNNGSWERKZEUGEN ZUR BEARBEITUNG VON BELAG BILDENDEN STÄHLENUSE OF CUTTING TOOLS FOR MACHINING STEEL FORMING COVERING
Es ist bekannt Zerspanungswerkzeuge, die mit einer Auflage aus Hartstofflegierungen mit hoher Warmverschleißfestigkeit ausgestattet sind zu verwenden zur Bearbeitung von Belag bildenden Stählen. Es sind dies Stähle, die an den Werkzeugschneiden nichtmetallische Ablagerungen abscheiden, wodurch deren Verschleiß erheblich herabgesetzt wird. Es wurde nachgewiesen, daß diese Ablagerungen auf den Werkzeugschneiden von nichtmetallischen Einschlüssen in den Stählen herrühren, die bei der Desoxidation des Stahles gebildet werden. Durch geeignete Erschmelzungs- und Desoxidationsverfahren gelang es so, in reproduzierbarer Weise Stähle herzustellen, deren Bearbeitung innerhalb weiter Schnittge·* schwindigkeitsbexeiche mit wesentlich geringerem Werkzeugverschleiß möglich ist als bei gleichartigen Stählen ohne Belag bildende Einsätze. Bei der Herstellung dieser Belag bildenden Stähle haben sich als Desoxydationsmittel Legierungen bewährt, die k5 - 90 % Silizium, 0,5 - k0 % Kalzium, 0,5 - 8 °/o Mangan, bis *f /o Aluminium und im Rest, neben Verunreinigungen, Eisen enthalten. Bei Verwendung dieser Legierungen zur Desoxydation der Stahlschmelzen entstehen im Stahl glasartige Einschlüsse, die einen It is known to use cutting tools, which are equipped with a support made of hard material alloys with high hot wear resistance, for the machining of coating-forming steels. These are steels that deposit non-metallic deposits on the tool cutting edge, which significantly reduces wear and tear. It has been shown that these deposits on the tool cutting edges result from non-metallic inclusions in the steels which are formed when the steel is deoxidized. By means of suitable melting and deoxidation processes, it was possible to produce steels in a reproducible manner, the machining of which is possible within a wide range of cutting speeds with significantly less tool wear than with similar steels without coating-forming inserts. In the preparation of this coating-forming steels have proven to be a deoxidant alloys k5 - 90% silicon, 0.5 - k0% calcium, 0.5 - 8 ° / o manganese, up * f / o aluminum, and the rest, in addition to Contaminants containing iron. When using these alloys to deoxidize the steel melts, glass-like inclusions arise in the steel

In the case of the machining Machining elevated temperatures soften these inclusions; they come to flow and finally stay lent to stick to the cutting edge of the tool.
