Patentanspruch:Claim: Verwendung einer zähen, kittartigen und mit Schleifkörneni durchsetzten, plastisch verformbaren Masse wie beispielsweise Isopropylstearat als Weichmacher und Silikonfett als Schmiermittel enthaltender Silikonkitt, die unter Druck an zu bearbeitenden Werkstückoberflächen und/oder -kanten vorbeigepreßt wird, zum Entgraten, Kantenrunden und Glätten der Oberfläche von Werkstücken.Use of a tough, putty-like and plastically deformable one interspersed with abrasive grains Containing mass such as isopropyl stearate as a plasticizer and silicone grease as a lubricant Silicone putty applied under pressure to workpiece surfaces and / or edges to be machined is pre-pressed for deburring, edge rounding and smoothing the surface of workpieces. Die Erfindung betrifft die Verwendung einer zähen kittartigen und mit Schleifkörnern durchsetzten, plastisch verformbaren Masse zum Entgraten, Kantenrunden und Glätten von Werkstücken. Es handelt sich dabei um Werkstücke, die mit durchgehenden Bohrungen oder Kanälen versehen oder in einer zusammen mit dem Werkstück einen durchgehenden Leitkanal bildenden Fassung angeordnet sind, wobei die Masse unter Druck an den zu bearbeitenden Werkstückflächen vorbeigepreßt wird.The invention relates to the use of a tough, putty-like material interspersed with abrasive grains, plastic Deformable compound for deburring, rounding edges and smoothing workpieces. These are around workpieces that are provided with through bores or channels or in one together with the workpiece a continuous guide channel forming socket are arranged, with the mass below Pressure is pressed past the workpiece surfaces to be processed. Es ist bekannt, solche Bearbeitungen mit einer losen, z. B. pulverförmigen oder körnigen Schleifmasse dadurch vorzunehmen, daß entweder die zu bearbeitenden Werkstücke oder die Schleifmasse oder beide relativ zueinander bewegt werden. Um hierbei die Schleifwirkung zu erhöhen, ist es aus der DT PS 9 65 296 ferner bekannt, die Schleifmasse bei dieser relativen Bewegung zum Werkstück unter Druck zu setzen. Nach bekannten Vorschlägen kann dies beispielsweise dadurch geschehen, daß das in einen Behälter eingefüllte Schleifmittel mittels eines mit Spannschrauben anziehbaren Preßdeckels oder eines druckmittelbeaufschlagten Kolbens komprimiert und dar.ii das an einem beweglichen Werkstückträger angebrachte, in das Schleifmittel eintauchende Werkstück im Schleifmittelbehälter gedieht oder anderweitig bewegt wird. Nach einem anderen bekannten Vorschlag kann auch der Werkstückträger ortsfest angeordnet und der Schleifmittelbehälter drehbar oder auf sonstige Weise beweglich gelagert sein. Für eine drehbare Lagerung des Schleifmittelbehälters hat man auch schon vorgesehen, die Drehzahl so zu bemessen, daß die beim Drehen des Behälters auf das Schleifmittal ausgeübte Zentrifugalkraft zur Druckerhöhung in der Schleifmasse ausgenutzt werden kann. Für eine magnetisch ansprechende Schleifmasse, z. B. ein Gemisch aus Karborund, Weicheisenpulver und Schmieröl, hat man auch schon vorgesehen, die Schleifmasse bezüglich eines darin eingebetteten Werkstückes durch magnetische Beeinflussung in eine hin- und hergehende Bewegung zu versetzen.It is known to work with a loose, z. B. to make powdery or granular grinding material that either the to be processed Workpieces or the grinding mass or both are moved relative to one another. To do this with the grinding effect to increase, it is also known from DT PS 9 65 296, the grinding mass in this relative movement to put the workpiece under pressure. According to known proposals, this can be done, for example happen that the abrasive filled into a container can be tightened by means of a clamping screw Press cover or a pressurized piston compressed and dar.ii that on a movable Workpiece carrier attached, workpiece immersed in the abrasive in the abrasive container thrives or is otherwise moved. According to another well-known suggestion, the Workpiece carrier arranged stationary and the abrasive container rotatable or movable in some other way be stored. For a rotatable storage of the abrasives container it has already been provided to measure the speed so that the centrifugal force exerted on the abrasive when rotating the container can be used to increase the pressure in the grinding compound. For a magnetically appealing Grinding compound, e.g. B. a mixture of carborundum, soft iron powder and lubricating oil, one has already provided the grinding compound with respect to a workpiece embedded therein through magnetic influence in to make a reciprocating motion. Bei allen diesen vorbekannten Oberflächenbearbeitungen von Werkstücken mit pulverförmiger oder körniger, flüssiger, brei- oder pastenförmiger Schleifmasse kommt die letztere nur mit verhältnismäßig niedrigem Berührungsdruck an den zu bearbeitenden Werkstückoberflächen vorbei. Die Schleifmasse muß nämlich in allen diesen Fällen in ihrer Konsistenz und Fließfähigkeit so eingestellt sein, daß sie die Erzeugung einer dem Bearbeitungszweck angepaßten Relativgeschwindigkeit zwischen Werkstück und Schleifmasse nicht beeinträchtigt. Auch den Anforderungen zum Fördern durch Leitungen mit einer Umlaufpumpe oder zum magnetischen Fördern in wechselnden Richtungen muß sie entsprechen. Dabei haben höhere Relativgeschwindigkeiten zwischen Schleifmasse und Werkstück häufig den Nachteil, daß Wirbel oder Totzonen im Arbeitsbereich des Schleifmittels entstehen können, die die Gleichmäßigkeit der Bearbeitung beeinträchtigen.In all of these previously known surface treatments of workpieces with powdery or granular, liquid, pulp or paste-like grinding material, the latter only comes with a relatively low amount Contact pressure past the workpiece surfaces to be machined. The grinding compound must be in In all of these cases, their consistency and flowability must be adjusted so that they produce a dem Processing purpose adapted relative speed between workpiece and grinding material is not impaired. Also the requirements for conveying through lines with a circulation pump or to the magnetic It must correspond to conveying in alternating directions. They have higher relative speeds between the grinding compound and the workpiece often has the disadvantage that eddies or dead zones in the work area of the abrasive, which affect the uniformity of processing. Der Erfindung liegt die Aufgabe zugrunde, die Wirtschaftlichkeit des Entgratens, Kantenrundens und Glättens der Oberfläche von Werkstücken nach dem vorbekannten Verfahren, nämlich dem Vorbeibewegen einer Schleifmasse an ortsfest angeordneten Werkstücken, zu verbessern.The invention is based on the problem of economy deburring, edge rounding and smoothing the surface of workpieces according to the previously known Method, namely moving a grinding compound past fixed workpieces, to improve. Diese Aufgabe wird erfindungsgemäß gelöst durch die Verwendung einer zähen, kittartigen und mit Schleifkörnern durchsetzten, plastisch verformbaren Masse wie beispielsweise Isopropylstearat als Weichmacher und Silikonfett a!s Schmiermittel enthaltender Silikonkitt, die unter Druck an den zu bearbeitenden Werkstückoberflächen und/oder -kanten vorbeigepreßt wird.This object is achieved according to the invention by the use of a tough, putty-like and with Plastically deformable material interspersed with abrasive grains, such as isopropyl stearate as a plasticizer and silicone grease as a lubricant-containing silicone cement, which is applied under pressure to the Workpiece surfaces and / or edges is pressed past. Bei Verwendung einer derartigen Schleifmasse muß der Förderdruck zum Bewegen der Schleifmasse wesentlich erhöht werden, was gleichzeitig zu einer erhebliehen Steigerung der Schleifleistung führt.When using such an abrasive mass, the delivery pressure for moving the abrasive mass must be substantial be increased, which at the same time lead to a levy Increase in grinding performance.
