Es sind scheibenförmige Diamantziehsteine bekannt, die man nach Abnutzung des ersten Ziehlochs dadurch weiter verwendbar gemacht hat, daß man parallel dem alten Ziehloch ein zweites, nach dessen Abnutzung ein drittes usw. gebohrt hat. Dagegen hat man bei nach' den verschiedenen Richtungen ziemlich gleich großen, also mehr würfelförmigen ' Steinen an eine weitere Ausnutzung nach TJnbrauchbarwerden des ursprünglichen Ziehlochs bisher nicht gedacht.There are disc-shaped diamond drawing dies known, which you can use after the first one Has made the drawing hole usable by running parallel to the old drawing hole a second, after the wear and tear of which a third drilled, and so on. One has against it in the case of more or less the same size, i.e. more cube-shaped, in the various directions Stones to a further use after the original drawing hole becomes usable not thought so far.
Die Erfindung bezweckt nun, solche bereitsThe invention now aims at such already
mit einer Bohrung versehenen Steine dadurch weiter auszunutzen, daß quer zur ersten Bohrung ein weiterer Bohrkanal" angebracht wird. Dadurch erhält der zum Ziehen wertlos gewordene Stein einen vollständigen Neuwert. .To take advantage of stones provided with a hole further that transversely to the first Drilling another drilling channel "is attached. This makes it worthless for pulling The stone that has become completely new. .
Es ist selbstverständlich, daß durch Herstellung von weiteren Bohrungen in dem Stein in anderen die ersten kreuzenden Richtungen eine noch weitere Benutzbarkeit der Ziehsteine entsteht. .It goes without saying that by drilling more holes in the stone in other directions that cross the first directions, the drawing dies can be used even further arises. .
Je nach den Abmessungen der Steine kann man die sich kreuzenden Bohrungen sieh durchschneiden oder in einem Abstande aneinander .vorbeigehen lassen.Depending on the dimensions of the stones, you can see the intersecting holes cut through or let them pass each other at a distance.
