Description

Paßschleifen, insbesondere von Kurvenflächen Das Paßschleifen von Kurvenflächen wurde seither so durchgeführt, daß man die vorbereiteten, gegeneinander einzuschleifenden Flächen zunächst feinschliff und dann, um sie einander einzupassen, mit Hilfe von feinstgemahlenen und gesiebten Schleifmitteln, vorzugsweisse Schmirgel, Korund, Dnamant u. ä., in Gegenwart von Ölen schnell gegeneinanderlaufen ließ.Match grinding, especially of curved surfaces Curved surfaces have since been carried out in such a way that the prepared ones are against each other First, finely sand the surfaces to be ground and then, in order to fit them into one another, with the help of finely ground and sieved abrasives, preferably white emery, Corundum, Dnamant and the like quickly ran against each other in the presence of oils.

Der Nachteil eines solchen Einschleifens besteht darin, daß feinste Teilchen des Schleifmittels in der Oberfläche verbleiben und daß es nur schwierig möglich ist, eine Hochglanzpolitur durchzuführen.The disadvantage of such grinding is that it is extremely fine Particles of the abrasive remain in the surface and that it is difficult it is possible to carry out a high-gloss polish.

Es wurde nun gefunden, daß man diese Einpaßarbeit bedeutend erleichtern und vereinfachen kann dadurch, daß man die vorgeschliffenen, einzuschleifenden Teile innerhalb einer die Metalloberfläche angreifenden Lösung zu vorzugsweise rascher, gegebenenfalls der Geschwindigkeit nach wechselnder Drehbewegung bringt. Als solche Lösungen eignen sich je nach dem Metall, aus dem die einzuschleifenden Flächen bestehen, saure oder auch alkalische Lösungen, -die beizend und/oder schutzsc'hichtbildend auf das bzw. die betreffenden Metalle einwirken. Ist beispielsweise eine Gußeisenfläche gegen eine Stahlfläche einzuschleifen, -dann genügt es, wenn @die Lösung so eingestellt ist, d'aß sie bevorzugt die Gußeisenfläche angreift.It has now been found that this fitting work can be made considerably easier and can be simplified by having the pre-ground parts to be ground in within a solution attacking the metal surface, preferably faster, if necessary brings the speed after alternating rotary motion. As such Solutions are suitable depending on the metal from which the surfaces to be ground are made, acidic or alkaline solutions, -the caustic and / or protective layer-forming act on the metal or metals concerned. For example, is a cast iron surface to grind against a steel surface - then it is sufficient if @the solution is set this way is that it preferentially attacks the cast iron surface.

Zusammen mit der Lösung können, mindestens zu Beginn des Schleifens, Schleifpulver angewandt werden, um (die Einschleifwirkung durch Abtragen der veränderten Oberflächenschicht zu unterstützen. Durch die chemische Wirkung der Lösung wird ein Festsetzen der Schleifkörper vermieden. Vorzugsweise spült man die schleifpulverhaltige Lösung vor .dem letzten Einschleifen heraus und schleift mit schleifpulverfreier Lösung nach. Besonders günstig ist es, vor dem Beginn (des Schleifens mit Hilfe der Lösung eine Schicht auf den einzuschleifenden Flächen aufzubringen., beispielsweise einePhosphatschicht.Together with the solution, at least at the beginning of the grinding process, Abrasive powder can be applied to (the grinding effect by removing the changed Support surface layer. Due to the chemical action of the solution, a seizing of the grinding wheel avoided. It is preferable to rinse the abrasive powder-containing Solution before the last sanding and sanding with sanding powder-free Solution after. Very cheap it is before the beginning (of the grinding using the solution to apply a layer to the surfaces to be ground., for example a phosphate layer.

Das erfindungsgemäße Verfahren kann nicht nur angewandt werden in Fällen, in denen. zum Gegeneinanderlaufen bestimmte Flächen miteinander eingeschliffen werden sollen, sondern. es kann auch angewandt werden, um eine vorbereitete Fläche mit Hilfe einer Schleifform auf idie gewünschte geometrische Form zu bringen. Das: erfindungsgemäße Verfahren ermöglicht es, die größtmögliche Tragfähigkeit eines Paßsitzes zu erzielen.The method according to the invention can not only be used in Cases where. to run against each other certain surfaces ground together should be, but. it can also be applied to a prepared area to bring it to the desired geometric shape with the help of a grinding mold. That: The method according to the invention allows the greatest possible load-bearing capacity of a To achieve a snug fit.

Als Lösung für das Einschleifen von Gußeisen eignen sieh beispielsweise Phosphatierungslösungen, z. B. eine solche mit 19,5 g Zink je Liter, 23 g P2 05 je Liter, 24,5 g NO, je Liter. Dieser Lösung setzt man vorzugsweise Netzmittel zu, um das Eindringen zu der einzuschleifenden Fläche zu erleichtern. Das Verfahren ist ünsbesondere anwendbar für solche Flächenpaare, die als gegeneinander schnell laufende Maschinenteile eingesetzt werden und bei denen sehr hohe Passung und beste Gleiteigenschaften erforderlich sind.As a solution for the grinding of cast iron see, for example, phosphating solutions, z. B. one with 19.5 g zinc per liter, 23 g P2 05 per liter, 24.5 g NO per liter. Wetting agents are preferably added to this solution in order to facilitate penetration of the surface to be ground. The method is particularly applicable to those pairs of surfaces that are used as machine parts that run against each other and that require a very high degree of fit and excellent sliding properties.
