KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Das Schleifen von Profilen oder Facetten in Stein, Metall, Glas und anderen Stoffen wird bisher mittels umlaufender Schleifscheiben aus sehr, harter Masse ausgeführt, deren wirksame Umfangsfläche entsprechend den zu erhaltenden Profilen oder Facetten profiliert oder facettiert ist.Grinding of profiles or facets in stone, metal, glass and other materials is carried out so far by means of rotating grinding wheels made of very, hard mass, their effective circumferential surface profiled according to the profiles or facets to be obtained or is faceted.
Die Anwendung derartiger Schleifvorrichtmigcn hat den Nachteil, daß die Profile undThe use of such grinding devices has the disadvantage that the profiles and
ίο Facetten der' Schleifscheiben sich ' bald abnutzen und einer wiederholten, zeitraubenden und kostspieligen Nacharbeitung bedürfen, um die ursprüngliche richtige Form wieder herzustellen.ίο Facets of the 'grinding wheels' wear out soon and a repeated, time-consuming and require costly rework to get the original correct shape again to manufacture.
Die den Gegenstand der vorliegenden Erfindung bildende Schleifvorrichtung beseitigt diesen Übelstand dadurch, daß bei derselben die Profile oder Facetten, welche in eine Fläche einzuschleifen sind, in einer Scheibe aus weichem Metall, z. B. Blei oder Zinn, oder einer weichen Metallegierung eingearbeitet sind, wobei diese Schleifscheibe während des Schlcifvorganges noch mit einer gegen dieselbe angedrückten,, nach Bedarf anstellbaren, iilcichfalls profilierten oder facettierten Mutterwalzc aus harter Masse in Berührung steht, durch welche die Schleifscheibe während des Schleifens nachgearbeitet bezw. das durch die Abnutzung veränderte Profil wieder hergestellt wird.The grinding apparatus which is the subject of the present invention is eliminated this disadvantage in that in the same the profiles or facets, which in a Surface are to be grinded in a disc made of soft metal, e.g. B. lead or tin, or a soft metal alloy are incorporated, this grinding wheel during the Grinding process still with a pressed against the same, adjustable as required, iilcichfall profiled or facetted mother rollsc is made of hard mass in contact, through which the grinding wheel during the Reworked grinding respectively. the profile changed by wear and tear is restored will.
Eine solche Vorrichtung ist in der Zeichnung in schematischer Weise in Seitenansicht (Fig. i) und Stirnansicht (Fig. 2) veranschaulicht. Such a device is shown schematically in the drawing in a side view (Fig. I) and front view (Fig. 2) illustrated.
3S Die Platte a, z. B. aus Glas, welche bei Otr dargestellten Ausführungsform der Vorrichtung mit parallelen Längsrillen b versehen werden soll, ist in einer passenden, verschiebbaren Unterlage c eingespannt. Oberhalb derselben befindet sich die umlaufende Scheibe d aus weichem Metall oder einer weichen . Metallegierung. Um nun die Formänderungen der gegen die Platte α angedrückten Umfangsrillcn der weichen Scheibe beständig und in allen Teilen auszugleichen bezw. allen Rillenteilen der Schleifscheibe der Platte immer wieder das richtige Profil zu geben, steht der Rand der Schleifscheibe d mit einer entsprechend profilierten Mutterwalze, f aus hartem Material (Stahl oder dergl.) unter Druck in Eingriff. Die Anpressung der Mutterwalze f kann dauernd oder durch zeitweise Nachstellung der Mutterwalze geschehen. Die mit der Schleifscheibe d sich drehende Walze f dringt mit ihren Ringrippen in die Rillen der Scheibe ein und gibt den letzteren wieder ihre. ursprüngliche, dem verlangten Profil entsprechende Form, so daß stets das gleiche Profil auf die zu schleifende Platte einwirkt. 3 S The plate a, e.g. B. made of glass, which is to be provided with parallel longitudinal grooves b in the embodiment of the device shown in Otr, is clamped in a suitable, displaceable base c. Above the same is the revolving disk d made of soft metal or a soft metal. Metal alloy. In order to compensate for the changes in shape of the circumferential grooves of the soft disk pressed against the plate α consistently and in all parts respectively. To give all the groove parts of the grinding wheel of the plate the correct profile over and over again, the edge of the grinding wheel d is in contact with a correspondingly profiled master roll f made of hard material (steel or the like) under pressure. The pressing of the mother roll f can be done permanently or by temporarily readjusting the mother roll. The roller f rotating with the grinding wheel d penetrates with its annular ribs into the grooves of the disk and gives the latter back theirs. original shape corresponding to the required profile, so that the same profile always acts on the plate to be ground.
Zum Gebrauch wird das eingespannte, zu bearbeitende Stück entgegen der Drehungsrichtung der Schleifscheibe bewegt, wobei zwischen die im Umfange der letzteren eingearbeiteten Rillen und das Werkstück ein Schleifpulver eingebracht wird.For use, the clamped piece to be machined is moved against the direction of rotation of the grinding wheel, with between the grooves incorporated in the circumference of the latter and the workpiece Grinding powder is introduced.
