 der Schrauben   1a   festgespannt, ein Werkzeug im   Träger     3'7   mittels der Schraube 39 festgeklemmt und mittels der Schraube 37'der Träger 37 im Schlitten 15 axial gegen die zu schneidende Scheibe bewegt. 



  Durch Drehung der Kurbel 6 wird der Schnitt bewirkt. 



   Wie ersichtlich, ist jeder die Schnittgenauigkeit gefährdende Handgriff durch die Erfindung vermieden. 



   Ebenso wie im vorliegenden Falle das Werkzeug bzw. der Werkzeugträger alle Einstellbewegungen ausführt, kann natürlich auch der   Werkstüokträger   (die Einspannscheibe) die Einstellbewegungen ausführen. In diesem Fall ist das Werkzeug ortsfest und die Einspannscheibe auf einem, vor der Werkzeugspitze verstellbaren Schlitten angeordnet. 



   PATENT-ANSPRÜCHE :
1. Vorrichtung zum Schneiden von Uhrgläsern aus durchscheinendem oder durchsichtigem Material, gekennzeichnet durch die Anordnung zweier messlehrenartig gegeneinander beweglicher Arme oder   Anschläge   (35,   36),   von denen der eine mit dem   Werkzeug-oder Werkstückträger   derart fest verbunden ist, dass bei Einstellung der Arme auf den Durchmesser der Uhrglasfassung die Werkzeugspitze sich in der Arbeitsstellung in dem dem erforderlichen Uhrglashalbmesser entsprechenden Abstand von der geometrischen Achse des   Werkstüekträgers   (Einspannscheibe) befindet.

 of the screws 1a, a tool is clamped in the carrier 3'7 by means of the screw 39 and by means of the screw 37 'the carrier 37 is moved axially in the slide 15 against the disc to be cut.



  The cut is effected by turning the crank 6.



   As can be seen, any manipulation that could jeopardize the cutting accuracy is avoided by the invention.



   Just as in the present case the tool or the tool carrier carries out all the adjustment movements, the workpiece carrier (the clamping disk) can of course also carry out the adjustment movements. In this case, the tool is stationary and the clamping disk is arranged on a slide that can be adjusted in front of the tool tip.



   PATENT CLAIMS:
1. Device for cutting watch glasses made of translucent or transparent material, characterized by the arrangement of two arms or stops (35, 36) which can be moved relative to one another like measuring gauges, one of which is firmly connected to the tool or workpiece carrier so that when the arms are set on the diameter of the watch glass frame, the tool tip is in the working position at the distance from the geometric axis of the workpiece carrier (clamping disk) corresponding to the required watch glass radius.

 

Claims (1)

2. Vorrichtung nach Anspruch 1, dadurch gekennzeichnet, dass die Anschläge (35, 36) auf zwei gegenläufig bewegbaren, von einer mit zwei gegenläufigen Gewinden gleicher Steigung versehenen Schraubenspindel betätigten Schlitten (15, 34) angeordnet sind, von denen einer das Werkzeug oder den Werkstückträger (Einspannseheibe) trägt. 2. Device according to claim 1, characterized in that the stops (35, 36) are arranged on two oppositely movable carriages (15, 34) operated by a screw spindle provided with two opposing threads of the same pitch, one of which is the tool or the Workpiece carrier (clamping disk) carries. 3. Vorrichtung nach Anspruch 1, dadurch gekennzeichnet, dass das Werkzeug im Werkzeugträger axial verschiebbar und feststellbar ist und der Werkzeugträger ebenfalls axial einstellbar am Schlitten angeordnet ist. 3. Apparatus according to claim 1, characterized in that the tool is axially displaceable and lockable in the tool carrier and the tool carrier is also arranged axially adjustable on the slide.
