Description

Patentiert im Deutschen Reiche vom 16. Dezember 1933 abPatented in the German Empire on December 16, 1933

Man hat schon hochporöse Schleifscheiben unter Verwendung eines ,aus Barzlösung bestehenden zusätzlichen Bindemittels hergestellt, indem man die vorgebundenen Schleifscheiben mit einer dünnflüssigen Harzlösung, wie Bakelit o. dgl., ein oder mehrere Male tränkte. Bei diesem Tränken ist es jedoch sehr schwierig, durchaus gleichmäßige Schleifscheiben bzw. Schleifkörper, besonders solche größererOne already has highly porous grinding wheels using one made of Barz solution additional binder made by removing the pre-bonded grinding wheels soaked one or more times with a thin resin solution such as Bakelite or the like. at With this soaking, however, it is very difficult to produce perfectly uniform grinding wheels or Abrasive tools, especially larger ones

ίο Stärke, zu erhalten, da sich die Schleifscheiben nach der Auflagefläche anreichern. Wenn es auch mitunter durch geeignete Maßnahmen gelingt, diese Anreicherung in praktisch noch zulässigen Grenzen zu halten, so versagt dieses Verfahren, für hochwertige Schleifscheiben, beispielsweise für Rund- und Innenschliff, bei welchen es auf eine unbedingte Gleichmäßigkeit des Schleifscheibengefüges ankommt.ίο strength to get as the grinding wheels enrich after the contact surface. Even if it succeeds sometimes through suitable measures, this enrichment in practical If this method still fails to admissible limits, it will fail for high quality Grinding wheels, for example for round and internal grinding, which are unconditional Uniformity of the grinding wheel structure matters.

Nach den Gedanken der Erfindung wird eine völlige Gleichmäßigkeit in der Verteilung des zusätzlichen Harzbindemittels über die Oberfläche der einzelnen Schleifkörner durch die ganze Schleifmasse dadurch erzielt, daß die Behandlung der Schleifscheiben oder Schleifkörper mit erhärtenden Tränkungsmitteln durch Schleudern erfolgt. Das Schleudern kann durch rasche Drehung der Schleifscheibe um. die eigene Achse oder um eine Achse, welche außerhalb dieser Drehachse liegt, geschehen. Nach dem Schleudern wird die Schleifscheibe an der Luft getrocknet und bei der erforderlichen Temperatur im Ofen fertig gehärtet.According to the idea of the invention, there is complete uniformity in the distribution of the additional resin binder through the surface of the individual abrasive grains the whole grinding mass achieved in that the treatment of the grinding wheels or Abrasive bodies with hardening impregnating agents are carried out by spinning. The skidding can be turned around by quickly turning the grinding wheel. its own axis or around a Axis, which is outside of this axis of rotation, happen. After spinning it will the grinding wheel is air-dried and in the oven at the required temperature hardened.

Auf diese Weise entstehen hochporöse Schleifscheiben mit besonders hoher Gleichmäßigkeit des Schleifscheibengefüges.In this way, highly porous grinding wheels with particularly high uniformity are created of the grinding wheel structure.
