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.
