Abstract
Description
Die
Erfindung betrifft ein Verfahren sowie eine Vorrichtung zum Ätzen von
Bohrungen, gemäß dem Oberbegriff
des Anspruchs 1, wie es aus der gattungsbildend zugrundegelegten
Aus
der
Die Aufgabe der Erfindung ist es daher, das zugrunde gelegte Verfahren bzw. die zugrunde gelegte Vorrichtung dahingehend weiter zu entwickeln, dass das Arbeitsergebnis hinsichtlich der Wandung der Bohrung zumindest gleichmäßiger ist.The The object of the invention is therefore, the underlying method or to develop the underlying device to the effect that the work result in terms of the wall of the bore at least is more uniform.
Die Aufgabe der Erfindung wird erfindungsgemäß mit einem Verfahren mit den Verfahrensschritten gemäß Anspruch 1 bzw. mit einer Vorrichtung mit den Merkmalen des Anspruchs 12 gelöst. Durch die gesteuert oszillierende Bewegung – d.h. durch die gezielte Auf- und Abwärtsbewegung – der Durchflussöffnungen innerhalb der Bohrung und entlang der Rotationsachse während des Austritts des Arbeitsmediums kann der Abtrag an Material an der Wandung der Bohrung zumindest gleichmäßiger vorgenommen werden.The The object of the invention according to the invention with a method with the Process steps according to claim 1 or with a device having the features of claim 12 solved. By the controlled oscillating motion - i. through the targeted and downward movement - the flow openings within the bore and along the axis of rotation during the Outflow of the working medium can be the removal of material on the wall the bore at least made more uniform become.
Die Erfindung kann generell zum Strukturieren von Mantelflächen von Bohrungen, vorzugsweise zum Ätzen von Bohrungen verwendet werden. Insbesondere dient es zum Freilegen von Primärkristallen auf der Oberfläche von Zylinderlaufbahnen. Insbesondere kann mit dem erfindungsgemäßen Verfahren bzw. der Vorrichtung die Oberfläche gezielt mit einer Mikrostrukturierung versehen werden; es können dadurch Vertiefungen mit definierter Größe, Geometrie Tiefe und Anordnung in der entsprechende Oberfläche herausgeätzt werden. Diese Verwendung ist unabhängig davon, ob es sich um eine Zylinderlaufbuchse oder eine ggf. bereits eingegossenen Zylinderlaufbuchse handelt. Gleiches gilt für gegossene oder gespritzte Zylinderlaufbahnen. Ferner kann das Verfahren auch noch zur Vorbereitung einer anschließend zu spritzenden Zylinderlaufbahn verwendet werden.The This invention may generally be used to pattern shell surfaces Holes, preferably for etching used by drilling. In particular, it is used for exposure of primary crystals the surface of cylinder liners. In particular, with the method according to the invention or the device, the surface be specifically provided with a microstructuring; it can do it Wells with defined size, geometry Depth and arrangement in the corresponding surface are etched out. This use is independent of it, whether it is a cylinder liner or possibly already cast-in cylinder liner acts. The same applies to cast or injection molded cylinder liners. Furthermore, the method can also to prepare for a subsequent used to be injected cylinder liner.
Sinnvolle Ausgestaltungen der Erfindung sind den Unteransprüchen entnehmbar. Im Übrigen wird die Erfindung anhand eines in der einzigen Figur dargestellten Ausführungsbeispiels näher erläutert.meaningful Embodiments of the invention are the dependent claims. Incidentally, will the invention with reference to an embodiment shown in the single figure explained in more detail.

Bei den Arbeitsmedien handelt es sich insbesondere um abrasiv wirkende Säuren oder Laugen sowie um Spül- und/oder Reinigungs- und/oder Trockenmittel wie insbesondere Wasser oder Druckluft.at The working media are in particular abrasive acids or lyes, as well as to rinse and / or cleaning and / or drying agents, in particular water or compressed air.

Arbeitsergebnis kann dadurch die Wandung
Da es sich bei dem Arbeitsmedium vorzugsweise um eine Säure oder eine Lauge handelt, ist es sinnvoll, den Leitwert und/oder den Druck und oder das Zuströmvolumen des Arbeitsmediums vor dem Austritt aus den Durchflussöffnungen zu ermitteln. Durch diese Maßnahmen kann der dazugehörige Arbeitsprozess auf einfache Weise gesteuert und/oder überwacht werden. Gleiches gilt für die Ermittlung der Temperatur und/oder des Leitwerts des Spülmittels, das nach der Abtragung erfolgt. Insbesondere zur schnellen Trocknung und damit zur Ermöglichung einer raschen Weiterverarbeitung der Bohrung wird der Ringraum anschließend noch von trocknender Luft durchströmt.Since the working medium is preferably an acid or a lye, it makes sense to determine the conductance and / or the pressure and / or the inflow volume of the working medium before Exit from the flow openings to determine. Through these measures, the associated work process can be easily controlled and / or monitored. The same applies to the determination of the temperature and / or the conductance of the detergent, which takes place after the removal. In particular, for rapid drying and thus to enable rapid further processing of the bore of the annular space is then still flowed through by drying air.
