Description
Verfahren zur Herstellung von Schleifwerkzeugen aus einer Mischung von Metall als Bindemittel und Schleifmitteln. Gegenstand der Erfindung sind sowohl das Verfahren zur Herstellung als auch Schleifwerkzeuge selbst aus einer Mischung von Metall als Bindemittel und Schleifmitteln.Process for the manufacture of grinding tools from a mixture of metal as binders and abrasives. The invention relates to both the process of making as well as grinding tools themselves from a mixture of metal as binders and abrasives.
Die bisherigen Schleifscheiben mit keramischer, chemischer oder vegetabilischer Bindung zeigen verschiedene Nachteile, welche sich besonders bei hohen Umfangsgeschwindigkeiten bemerkbar machen. Die Hauptnachteile sind sogenanntes Explodieren, leichte Zerbrechlichkeit, Zerstörung bei Erwärmung, Nichtverwendbarkeit der Überreste.The previous grinding wheels with ceramic, chemical or vegetable Binding show various disadvantages, which are particularly evident at high peripheral speeds to make noticable. The main disadvantages are so-called exploding, easy fragility, Destruction when heated, the remains cannot be used.
Zweck des neuen Verfahrens und der beschriebenenAusführungsformist, Schleifscheiben wesentlich weniger empfindlich zu machen gegen Zerspringen bei hohen Geschwindigkeiten, Stoß oder Schlag, Erwärmung und zerstörte oder unbrauchbar gewordene Scheiben wieder verwenden zu können, ohne daß Bindestoff und Schleifmittel verloren gehen.The purpose of the new method and the described embodiment is To make grinding wheels much less sensitive to cracking at high Velocities, shock or impact, warming and destroyed or unusable To be able to use discs again without losing binding material and abrasives walk.
Die Beschreibung schildert das Verfahren und eine Ausführungsform von Schleifwerkzeugen, bei der Metall oder Legierungen mit dem Schleifmittel zu Schleifscheiben beliebiger Gestalt verarbeitet werden.The description describes the method and an embodiment of grinding tools, when metal or alloys with the abrasive too Grinding wheels of any shape can be processed.
Die Herstellung erfolgt derart, daß sich unter Wärmezufuhr die Bindung der einzelnen Teile zerkleinerten oder feinkörnigen Metalls untereinander und mit dem Schleifmittel vollzieht. Gleichzeitig wird die beim Pressen erzeugte Wärme mitbenutzt. Die Erwärmung wird aber nur bis zum Sintern der Metallteile getrieben, damit das Metall, ohne vollständig zu schmelzen, in sich und mit dem Schleifmittel zusammenbackt.The production takes place in such a way that the bond is formed with the supply of heat of the individual parts of crushed or fine-grained metal with one another and with the abrasive. At the same time, the heat generated during pressing is also used. The heating is only driven up to the sintering of the metal parts, so that Metal cakes in itself and with the abrasive without completely melting.
Außer Blei, das für allgemeine Verwendung ::u weich sein dürfte, können Legierungen, wie Zinn und Antimon, Aluminium, Kupfer und andere Metalle verwendet werden.Except for lead, which should be soft for general use :: u can Alloys such as tin and antimony, aluminum, copper and other metals are used will.
