Description
Schleifkörper. Gegenstand vorliegender Erfindung ist ein Schleifkörper mit Bindemittel. Erfin dungsgemäss weist das Bindemittel Metall pulver auf. Schleifkörper, z. B. Schleifschei ben, die mit Kunstharz als Bindemittel und solche die mit organischen Bindemitteln her gestellt werden, erhalten, wenn diesem Bindemittel Metallpulver, z. B. feinstes Alu- miniumpulver zugeführt wird, eine grössere Festigkeit. Beim Schleifvorgang brechen die Ränder solcher Schleifkörper weniger leicht aus.
Bei Verwendung des Metallpulvers bei keramisch verbundenen Schleifkörpern wird erreicht, dass das eigentliche Schleifmittel einen besseren Halt im Träger hat. Die Bin dung ist vollkommener. Ein weiterer Vorteil besteht darin, dass die Arbeiter, welche mit solchen Schleifkörpern arbeiten müssen, der Gefahr der Silicose nicht ausgesetzt sind. Es wurde die Wahrnehmung gemacht, dass der Staub des Schleifkornes, sowie der Staub des keramischen Bindemittels, wenn mit Metall staub versetzt, in der Lunge des Menschen keine nachteiligen Erscheinungen zeitigt.
Als Metallpulver wird vorzugsweise Alu- minium oder eine Aluminiumlegierung in Pulverform verwendet. Das Pulver wird zweckmässig möglichst in feinem Zustand bei der Herstellung des Schleifkörpers beige fügt.
Statt Aluminium könnten auch andere Metalle Verwendung finden.
Neben organischen, können auch an organische Bindemittel, z. B. mineralische, wie Wasserglas, zur Verwendung gelangen.
Grinding wheel. The present invention relates to an abrasive article with a binder. In accordance with the invention, the binder comprises metal powder. Grinding wheel, e.g. B. grinding disks, which are made with synthetic resin as a binder and those with organic binders ago, obtained when this binder is metal powder, eg. B. finest aluminum powder is supplied, a greater strength. The edges of such grinding tools are less likely to break off during the grinding process.
When using the metal powder with ceramic bonded grinding tools, the actual abrasive has a better hold in the carrier. The bond is more perfect. Another advantage is that the workers who have to work with such grinding wheels are not exposed to the risk of silicosis. The perception was made that the dust of the abrasive grain, as well as the dust of the ceramic binder, when mixed with metal dust, does not cause any adverse phenomena in the human lungs.
The metal powder used is preferably aluminum or an aluminum alloy in powder form. The powder is expediently added in a fine state as possible during the manufacture of the grinding wheel.
Instead of aluminum, other metals could also be used.
In addition to organic, organic binders such. B. mineral, such as water glass, are used.
