Description
Das Feinschleifaggregat 5 weist eine zentrale Exzenterwelle 8 mit einerseits angeschlossenem Exzenterzapfen 10 auf, der mittelbar oder unmittelbar (z. B. unter Zwischenschaltung einer Kugellagerrolle Il oder dergleichen) mit Schlitzführung in einen mit dem Werkzeugträger 6 verbundenen Oszillationsschlitten 12 einfaßt, wobei femer der Oszillationsschlitten 12 über eine Oszillationsschlittenführung 13 mit einer die Exzenterwelle 8 umgebenden Lagerhülse 14 verbunden Ist. Die Lagerhülse 14 ist auf- und niederbewegbar und ihrerseits im Maschinengehäuse 15 gelagert. Der Drehantriebsmotor wurde nicht gezeichnet, er gibt sein Drehmoment auf das in der Figur eingezeichnete, auf die Exzenterwelle 8 aufgesetzte Ritzel 16 ab.The fine grinding unit 5 has a central eccentric shaft 8 with an eccentric pin 10 connected on the one hand, which directly or indirectly (e.g. with the interposition of a ball bearing roller II or the like) with a slot guide in an oscillation slide 12 connected to the tool carrier 6, with the oscillation slide 12 Is connected via an oscillation slide guide 13 to a bearing sleeve 14 surrounding the eccentric shaft 8. The bearing sleeve 14 can be moved up and down and is in turn mounted in the machine housing 15. The rotary drive motor was not shown; it outputs its torque to the pinion 16 shown in the figure and placed on the eccentric shaft 8.
Die Lagerhülse 14 ist mit ihrer Oszillationsschlittenführung 13 und dem angeschlossenen Oszillationsschlitten 12 zum Zwecke der Einstellung der horizontalen Oszillationsrichtung um ihre Achse verdrehbar. Sie ist dazu mit einem entsprechenden DrehsteUtrieb ausgerüstet, der im einzelnen nicht gezeichnet ist, jedoch an dem auf die Lagerhüise !4 aufgesetzten Ritzel 17 angreiftThe bearing sleeve 14 is with its oscillation slide guide 13 and the connected oscillation slide 12 rotatable about its axis for the purpose of setting the horizontal oscillation direction. she is equipped with a corresponding rotary drive, which is not drawn in detail, but on the on the Lagerhüise! 4 attached pinion 17 engages
Die Exzenterwelle 8 ist in der Lagerhülse ί-ί mittels Vertikalstelltrieb 18 vertikal verstellbar und besitzt einen in bezug auf die Exzenterwellenachse 19 schrägen Exzenterzapfen 10. Dieser ist zum Zwecke der Einstellung der horizontalen Oszillationsamplitude bei vertikaler Verstellung der Exzenterwelle 8 unterschiedlich tief (mittelbar oder unmittelbar) in die Schlitzführung des Oszillationsschlittens 12 eintauchbar.The eccentric shaft 8 is in the bearing sleeve ί-ί means Vertical actuating drive 18 is vertically adjustable and has a slope with respect to the eccentric shaft axis 19 Eccentric pin 10. This is for the purpose of adjusting the horizontal oscillation amplitude with vertical Adjustment of the eccentric shaft 8 different depths (indirectly or directly) in the slot guide of the Oscillation slide 12 can be immersed.
Der DrehsteUtrieb und der Vertikalstelltrieb 18 sind unabhängig voneinander zu betätigen. Der Vertikalstelltrieb 18 ist im Ausführungsbeispiel ein einfacher Spindelstelltrieb mit Stellmutter 20, so daß diese vertikale Verstellung der Exzenterwelle 8 von Hand durchgeführt werden kann. Eine einmal getroffene Einstellung ist auf geeignete, aber nicht gezeichnete Weise festsetzbar. — Das Feinschleifwerkzeug 21 besteht aus Gießharz. Es wurde in der funkenerosiv hergestellten Auskammerung 2 geformt und ist durch Schrumpfung beim Aushärten ein wenig kleiner als die Auskammerung 2. Der Spalt zwischen der Auskammerung 2 und dem Feinschleifwerkzeug 21 erscheint in der Zeichnung übertrieben, ist jedoch so groß, daß das Feinschleifwerkzeug 21 die beschriebenen Feinschleifbewegungen ausführen kann.The rotary actuator and the vertical actuator 18 are to be operated independently of one another. The vertical actuator 18 is a simple spindle actuator with adjusting nut 20, so that this vertical Adjustment of the eccentric shaft 8 can be carried out by hand. An attitude made once can be fixed in a suitable, but not shown, way. - The fine grinding tool 21 consists of Cast resin. It was formed in the cavity 2 produced by electrical discharge machining and is due to shrinkage when hardening a little smaller than the cavity 2. The gap between the cavity 2 and the fine grinding tool 21 appears exaggerated in the drawing, but is so large that the fine grinding tool 21 can perform the fine grinding movements described.

Zur Lösung dieser Aufgabe lehrt die Erfindung, daßto work.
To solve this problem, the invention teaches that

DE-PS 28 27 543). Das wird im hergestellten Auskammerung andererseits in Kauf ge- folgenden anhand einer Zeichnung ausführlicher erläunommen werden müssen und stören. Zum Feinschleifen 55 tertThe invention relates to a generic, but the cast resin molding can also be used to manufacture a fine grinding tool without such an admixture, based on casting resin for fine grinding a spark erosion (see Rompps Chemie-Lexi-Werlcstück, in which fine grinding the fine grinding con. Volume 2, 1279). According to the invention, a tool is obtained with the addition of a fine grinding agent in the fine grinding tool, which is very precisely the countersunk in the way of the cavity and r <; The chambering of the fine grinding to be machined, spark erosion is initially adapted for a vertical grinding process, oscillating. or a cast resin molding is molded with which the fine circular movement is made. grinding process is carried out. The fact that the known method for producing a casting resin experiences a shrinkage as it hardens. Fine grinding tool (Machines and Tooling, 1969, 40 is in the context of the invention in a special way No. 4, pp. 43 to 45), the casting resin is used in the hollow mold. This shrinkage is in fact enough space in a special shape for the production of the fine grinding tool to be poured into the fine grinding tool and formed in the mold next for the vertical grinding process and then also a cavity by hardening. The fact that the casting resin only experiences sufficient play in small shrinkage during hardening of the fine grinding means and can in this way give the cavity, producing the play for very precise fine grinding tools. A fine grinding tool, which can be used in advance of the horizontal grinding process, can be enlarged for the fine grinding process by first performing the vertical fencing of a cavity made by spark erosion in the grinding process,
a metallic workpiece is not particularly well suited to the process according to the invention, because the tolerances between the mold hollow-set fine grinding tool is in particular determined space in the special shape for the manufacture of the for use in a device that is in special fine grinding tool on the one hand and the spark erosion rer way works (see. DE-PS 28 27 543). On the other hand, this will have to be explained in more detail in the produced chambering based on a drawing and will be disturbing. For fine grinding 55 tert
