Description

Verfahren zum Herstellen von Werkzeugen,. insbesondere zum Bearbeiten von Prägewalzen für ``"`verfilme Die Erfindung bezieht sich auf ein Verfahren zur Herstellung von Werkzeugen, deren eigentlich arbeitender Teil aus besonders hartem, kristallinem Stoff, z. B. Diamant, besteht. Derartige Werkzeuge werden hauptsächlich zur Bearbeitung von Gegenständen aus hartem Werkstoff verwendet, beispielsweise für zum Herstellen von Linsenrasterfilmen bestimmte Stahlwalzen, in die Rillen eingearbeitet werden. Method of making tools. especially for processing embossing rollers for `` "` `film The invention relates to a method for the production of tools, the actually working part of which is made of particularly hard, crystalline material, e.g. B. diamond. Such tools are mainly used for processing objects made of hard material, for example for steel rollers intended for the production of lenticular films, into which grooves are machined.

Bei der Herstellung der Walzen kommt es ganz besonders darauf an, daß die Rillen, sauber und .äußerst genau in die Walzenobe2' fläche eingearbeitet werden. Dies ist nur mit solchen Diamanten möglich, die mit großer Sorgfalt geschliffen werden und die erforderliche genaue Form besitzen.In the manufacture of the rollers, it is particularly important that the grooves are clean and worked into the surface of the roller surface extremely precisely will. This is only possible with diamonds that have been cut with great care and be in the exact shape required.

Die vorliegende Erfindung bezieht sich :nun auf ein Verfahren zur Herstellung einwandfrei geschliffener formgenauer Werkzeuge zum Bearbeiten von Prägewalzen für Linsenrasterfilme, die aus einem Ein- oder Spaltkristall bestehen. Für Werkzeuge sind bereits Stücke von Kristallen verwendet worden, jedoch in unbearbeitetem Zustand. So werden beispielsweise für Schnittzwecke Diamantsplitter ausgesucht, die eine keilförmig ausgebildete Kante aufweisen, die beim Schneiden in den Werkstoff eindringt. Es ist bereits vorgeschlagen worden, Werkzeuge zum Bearbeiten von Prägewalzen aus einem geschliffenen Arbeitsdiamanten so herzustellen, daß die Erzeugende einer etwa zylindrischen Arbeitsfläche parallel zu einer der Diamantachsen gelegt und gleichzeitig die Arbeitsfläche parallel zu der Erzeugenden geschliffen wird.The present invention relates: now to a method for Manufacture of perfectly ground, dimensionally accurate tools for processing embossing rollers for lenticular films that consist of a single or split crystal. For tools Pieces of crystals have already been used, but in an unworked state. For example, diamond chips are selected for cutting purposes that have a Have wedge-shaped edge that penetrates into the material when cutting. It has already been proposed to use tools for machining embossing rollers to produce a cut working diamond in such a way that the generatrix is about cylindrical work surface parallel to one of the diamond axes and placed at the same time the working surface is ground parallel to the generatrix.

Gemäß der Erfindung wird die Arbeitsfläche des Werkzeuges, die in an sich be-{ hannter Weise ganz oder angenähert die Form eines Zylinders hat, lediglich parallel zu der Erzeugenden des Zylinders geschliffen, also in beliebiger Richtung zu den Kristallachsen, ausgenommen jedoch parallel zu diesen. Auf diese Weise ist Gewähr dafür gegeben, daß die Bewegung des benutzten Schleifwerkzeuges längs der ganzen anzuschleifenden Fläche stets unter gleichem Winkel zu den Kristallachsen verläuft. Die Härte des Kristalls ist infolgedessen überall gleich groß, so daß bei gleicher Schleifarbeit pro Flächeneinheit an allen Teilen des Kristalls gleich viel Werkstoff abgetragen wird. Es ,ergibt sich also bei einer derartigen Bearbeitung des Werkzeuges der wesentliche Vorteil des immer gleichbleibenden Widerstandes.According to the invention, the working surface of the tool, which is shown in in a manner known per se has wholly or approximately the shape of a cylinder, only Ground parallel to the generating line of the cylinder, i.e. in any direction to the crystal axes, except, however, parallel to them. That way is Guaranteed that the movement of the grinding tool used along the entire surface to be ground always at the same angle to the crystal axes runs. The hardness of the crystal is consequently the same everywhere, so that with the same grinding work per unit area on all parts of the crystal the same a lot of material is removed. It thus arises from such a processing of the tool the essential advantage of the constant resistance.

An dem in den Fig. i und 2 dargestellten Diamanten soll die dachartig geformte Fläche längs der Kante i zylinderförmig abgerundet werden. Die endgültige Form dieser Abrundung, im zugehörigen Schnitt durch die gestrichelte Linie 2 angedeutet, wird dadurch erzeugt, daß das Schleifwerkzeug 4 parallel zu der Kante i bewegt wird, während der Diamant zweckmäßig um die Achse 3, die der ;endgültigen Abrundung 2 entspricht und in Fig. i durch die strichpunktierte Linie 3 angedeutet ist, geschwenkt wird. Diese Achse verläuft also parallel zu der rund zu schleifenden Kante i, so daß die Arbeitsfläche somit immer parallel zu der Erzeugenden der Zylinderfläche geschliffen wird. Auf diese Weise wird erreicht, daß die Schleifrichtung stets die gleiche Lage zu den Kristallachsen einnimmt.On the diamond shown in FIGS. I and 2, the roof-like shaped surface along the edge i are rounded cylindrically. The final Shape of this rounding, indicated in the associated section by the dashed line 2, is generated in that the grinding tool 4 is moved parallel to the edge i, while the diamond expediently around the axis 3, which is the; final rounding 2 corresponds and is indicated in Fig. i by the dash-dotted line 3, pivoted will. This axis therefore runs parallel to the edge i to be ground round, see above that the working surface is thus always parallel to the generatrix of the cylinder surface is sanded. In this way it is achieved that the grinding direction is always the occupies the same position to the crystal axes.
