Bei der Herstellung künstlicher Schleifsteine hat man dafür Sorge zu tragen, dass die Oberfläche des Steines porös und rauh ist. Dies wird bei den auf kaltem Wege erzeugten künstlichen Schleifsteinen dadurch erreicht, dass man ein möglichst scharfkantiges Schleifmittel verwendet, bei den gebrannten Schleifsteinen aber dadurch, dass man dem Gemenge aus Schleifmittel und Bindemittel noch Teer, Sägespäne oder andere verbrennbare Substanzen zusetzt, die beim Brennen verflüchtigt werden und Poren   zurücklassen. Die   auf

 steines bei dessen Benutzung selbsttätig, indem gewisse Bestandteile derselben aussplittern, wodurch Lücken entstehen Die Herstellung derartiger Schleifsteine erfolgt auf kaltem Wege. 



   Behufs Herstellung der Schleifsteine, deren   Obernäche so beschaffen   ist, dass sich ihre Rauheit immer von selbst erneuert,   mischt   man dem Gemenge aus Schleifmittel und Bindemittel eine zerkleinerte kristallinische Substanz bei, die sich durch weitgehende Teilbarkeit auszeichnet und welche daher beim Gebrauch des neuartigen künslichen Schleif. steines aus dessen Oberfläche in Form kleiner   Partikpicben ausbricht   oder   aussplittert,   wodurch die   Obernäche stets   rauh und porös   erhalten   wird.

   Substanzen, welche die angegebenen Eigenschaften besitzen, sind vor allem jene Mineralien, welche ein ähnliches Gefüge, wie der gewöhnliche Glimmer zeigen, also alle   Glimmerarten,   ferner die unter dein Namen   Eisenglimmer     bekannte Abart   des Eisenglanzes, dann glimmerhaltigeGesteine u. s. f. 



  Alle derartigen Körper haften an dem bei der Herstellung der Kunststeinmasse benutzten Bindemittel nur schwach, so dass sie von diesem bei der Benutzung des Steines nicht am   Aussplittorn   verhindert werden. 



     Behufs   Herstellung   der neuartigen künstlichen Schleifsteine werden Schleifmittel,   Bindemittel und der oben bezeichnete Zusatz in trockenem Zustande und in entsprechend zerkleinerter Form innig gemischt; nach dem Anfeuchten formt man die Masse, lässt sie erhärten und schleift die Oberfläche ab.   Der künstliche   Schleifstein ist nun bereits gebrauchsfertig.

   Artificial grindstone.
 EMI1.2
 
When making artificial whetstones, care must be taken that the surface of the stone is porous and rough. In the case of artificial whetstones produced by cold means, this is achieved by using an abrasive that is as sharp-edged as possible, but in the case of burned whetstones by adding tar, sawdust or other combustible substances to the mixture of abrasive and binding agent, which evaporates during the burning process and leave pores behind. The on

 stone automatically when it is used, in that certain components of the same splinter, creating gaps. Such grinding stones are produced in a cold way.



   For the production of the grinding stones, the surface of which is such that their roughness is always renewed by itself, a crushed crystalline substance is added to the mixture of abrasive and binding agent, which is characterized by extensive divisibility and which is therefore used when using the new artificial grinding. Stone breaks or splinters out of the surface in the form of small particle pics, whereby the surface is always rough and porous.

   Substances which have the specified properties are above all those minerals which have a structure similar to that of ordinary mica, i.e. all types of mica, furthermore the type of iron luster known under your name iron mica, then mica-containing stones and the like. s. f.



  All such bodies adhere only weakly to the binding agent used in the production of the artificial stone mass, so that they are not prevented by this when the stone is used on the splitting mandrel.



     For the production of the new artificial whetstones, abrasives, binders and the above-mentioned additive are intimately mixed in a dry state and in appropriately crushed form; After moistening, the mass is shaped, allowed to harden and the surface is sanded. The artificial whetstone is now ready to use.
