Abstract

The present invention permits the simultaneous facing of a storage disk from both sides, with regulation of uniform machining pressure and approximately the same relative machining speed in all diameter ranges.

Description

Planparallel erzeugte Programmträgerplatten, z. B. nach P 35 33 856.3, benötigen für bestimmte Anwen­ dungsfälle noch eine Bearbeitung zur Oberflächenver­ besserung. Da die Platte aus anwendungstechnischen Gründen sehr dünn sein muß, darf die mechanische Be­ lastung nicht überschritten werden. Außerdem be­ nötigt man, um eine sogenannte "Fließzerspanung" zu erzeugen, bestimmte Vorschubgeschwindigkeit = 20 m/s, die in allen Durchmesserbereichen gleich sein soll. Es ist nicht zu vermeiden, daß außerdem eine bestimmte Bearbeitungsstruktur entsteht, die jedoch in konzen­ trischen Ringen liegen sollte, um die spätere Pro­ grammier- und Ablesesicherheit zu unterstützen. Beide Bedingungen werden mit der vorliegenden Vor­ richtung erfüllt. Die Bearbeitungsgeschwindigkeit setzt sich aus der Umfangsgeschwindigkeit der Platte (1) und der der Werkzeuge (2 und 3) zusammen. Im Bereich des Außendurchmessers liegen diese Rich­ tungen nahezu rechtwinklig zueinander, und es bildet sich eine Komponente ; im Bereich des kleinen Durchmessers liegen beide Geschwindigkeiten in einer Ebene, so daß die Effektivgeschwindigkeit die Summe aus V 2 und V 3 ist.Program carrier plates generated plane-parallel, e.g. B. according to P 35 33 856.3, need for certain applications still processing for surface improvement. Since the plate must be very thin for technical reasons, the mechanical load must not be exceeded. In addition, in order to produce a so-called "flow machining", certain feed speeds = 20 m / s are required, which should be the same in all diameter ranges. It is unavoidable that a certain processing structure also arises, which, however, should lie in concentric rings in order to support the later programming and reading security. Both conditions are met with the present device. The processing speed is made up of the peripheral speed of the plate ( 1 ) and that of the tools ( 2 and 3 ). In the area of the outside diameter, these directions are almost at right angles to one another, and a component is formed; in the range of the small diameter both speeds lie in one plane, so that the effective speed is the sum of V 2 and V 3 .

Da die Platten zunehmend aus Glas gefertigt werden und sehr dünn sein müssen (0,6-1,9 mm), muß der Bearbeitungsdruck so einstellbar sein, daß er sich vollständig ausgleicht u. im übrigen permanent über­ wachbar ist. Mit einer Berührungserfassung, z. B. nach Patentanmeldung P 36 08 156.6, wird der erste Kontakt jedes einzelnen Werkzeugs (2 und 3) mit der Platte (1) erfaßt und über den Membranzylinder (4 od. 5) wird sofort reagiert. Die Platte wird über die Aufnahme (6) mit einer bestimmten Dreh­ zahl, angetrieben über den Motor M 3, wobei die Strom­ aufnahme des Motors nach dem gleichen Verfahren, wie obengenannt, die Gesamtleistung der Werkzeuge über­ wacht. Bei Überschreitung festgelegter Werte wird ein Nachschärfvorgang für die Werkzeuge erforderlich. Zu diesem Nachschärfvorgang wird statt einer Programm­ trägerplatte eine Nachprofilierscheibe eingespannt und über ein bestimmtes Programm zum Nachprofilieren zwi­ schen die Werkzeuge gebracht. Über die rechnerkontrol­ lierten Antrieb M 4 und M 5 wird ein definierter Werk­ zeugabtrag erzeugt, der zu einem neuen 0-Punkt führt, über den die Enddicke der Programmträgerplatten ge­ steuert wird.Since the plates are increasingly made of glass and have to be very thin (0.6-1.9 mm), the processing pressure must be adjustable so that it completely balances u. is also permanently monitored. With a touch detection, e.g. B. according to patent application P 36 08 156.6, the first contact of each tool ( 2 and 3 ) with the plate ( 1 ) is detected and the membrane cylinder ( 4 or 5 ) is immediately reacted. The plate is on the recording ( 6 ) with a certain speed, driven by the motor M 3 , the current consumption of the motor by the same method as mentioned above, the total power of the tools monitors. If the specified values are exceeded, the tools need to be resharpened. For this resharpening process, a re-profiling disc is clamped in place of a program carrier plate and brought between the tools via a specific re-profiling program. Via the computer-controlled drives M 4 and M 5 , a defined tool removal is generated, which leads to a new 0 point, via which the final thickness of the program carrier plates is controlled.

Die Nachprofilierscheibe hat eine definierte Dicke, die in diese Rechnung eingeht. Die gesamte Vorrichtung ist so gestaltet, daß eine optimale Handhabung mög­ lich ist, d. h.: Die Platten können auf die Aufnahmen (6) gegeben werden, gleichzeitig wird über einem Hub S 3 die Spannabe (7) gegen die Platte gefahren und über einem einstellbaren Basisdruck auf die Mem­ branzylinder (4 und 5) eine Spannkraft erzeugt, die ein sicheres Halten der Platte garantieren. Die Spann­ nabe (7) orientiert sich an der Aufnahme, so daß eine Mehrfachlagerung ausgeschlossen ist. Die erfor­ derliche Kraftregelung wird über ein Kardangelenk (9) übertragen. Die Ruhelagerung (8) für die Nabe tritt nur in der Ent- und Beladephase in Aktion.The post-profiling disc has a defined thickness, which is included in this calculation. The entire device is designed so that optimal handling is possible, ie: the plates can be placed on the receptacles ( 6 ), at the same time the hub ( 7 ) is driven against the plate via a stroke S 3 and over an adjustable base pressure on the Mem branzylinder ( 4 and 5 ) generated a clamping force that guarantee a secure hold of the plate. The clamping hub ( 7 ) is based on the receptacle, so that multiple storage is excluded. The necessary force control is transmitted via a universal joint ( 9 ). The resting position ( 8 ) for the hub only comes into action in the unloading and loading phase.
