Description

Verfahren zur Erzeugung gerillter Flächen auf metallischen Teilen von photographischen Kammern Die Erfindung bezieht sich auf ein Verfahren zur Erzeugung gerillter Flächen auf metallischen Teilen photographischer Kammern, bei dem die Rillen mit einem Span bildenden Werkzeug, z. B. einem Fräser, hergestellt werden.Process for producing grooved surfaces on metallic parts of photographic chambers The invention relates to a method of production grooved surfaces on metallic parts of photographic chambers, in which the Grooving with a chip forming tool, e.g. B. a milling cutter.

Es hat sich herausgestellt, daß beim Emaillieren der Lack an der scharfen Kante nicht hält und daß er von der scharfen Kante entweder in die Rille oder nach der Oberfläche der Platte hin abläuft.It has been found that when enamelling the lacquer on the sharp Edge does not hold and that it is either in the groove or after the sharp edge runs off the surface of the plate.

Diesem Übelstand begegnet man gemäß der Erfindung, indem man die gerillte Platte einem Sandstrahlgebläse oder einer ätzenden Flüssigkeit aussetzt, so daß die scharfen Kanten leicht abgerundet oder weggeätzt werden.This drawback is countered according to the invention by the grooved The plate is exposed to a sandblasting fan or a corrosive liquid, so that the sharp edges are slightly rounded or etched away.

Um in der gerillten Platte ein ungerilltes Feld zu haben, in das irgendwelche Mitteilungen, die für den Käufer bestimmt sind, eingraviert werden können, wird ein Teil der Platte ausgebohrt oder durchgedrückt und eine entsprechend große ungerillte Metallplatte eingesetzt. Diese Platte kann auch kreisförmig gerillt sein.In order to have an ungrooved field in the grooved plate in which any Messages intended for the buyer can be engraved a part of the plate drilled out or pushed through and a correspondingly large ungrooved one Metal plate used. This plate can also be grooved in a circle.
