Die bekannten Maschinen dieser Ausbildung leiden unter dem Mangel, daß zur Bildung des Lichtvorhanges bzw. der jeweiligen Lichtvorhänge zahlreiche optische Umlenkelemente an der Maschine angeordnet werden müssen, die relativ leicht verschmutzen, dejustiert oder beschädigt werden können. Auch gelingt es nicht immer, den Zugriffsraum der Maschine zum Arbeitsbereich zwischen Ständerkopf und Sockel von derartigen optischen Elementen freizuhalten, so daß die Arbeitsmöglichkeit an der Maschine beengt wird. Das Be- und Entladen der Maschine mit dem zu bearbeitenden Werkstück erfordert deshalb besondere zusätzliche Arbeitsgänge, die der Sicherung und Beseitigung von Teilen der Lichtschranke für die Dauer des zugehörigen Arbeitsvorganges angehen.The known machines of this training suffer from the deficiency that the formation of the light curtain or the respective light curtains numerous optical deflection elements must be arranged on the machine, which relative easily soiled, misaligned or damaged can. It is also not always possible to reduce the machine's access area to the work area between the column head and To keep the base free of such optical elements, so that the possibility of working on the machine is restricted. The loading and unloading of the machine with the workpiece to be processed therefore requires special additional operations, the safeguarding and removal of parts of the light barrier for the duration of the associated work process approach.
In Verbesserung von Maschinen der eingangs näher bezeichneton Bauart wird der vorliegenden Erfindung entsprechend vorgeschlagen, daß am Kopf des Maschinenständers an jeder der drei freien Zugriffsseiten der Maschine ein Mikrowellensender angeordnet ist, dessen ausgesendete Mikrowellenstrahlung die Zugriffsfläche überdeckt und über die Aufstellungsfläche der Maschine reflektiert einem am Kopf des Ständers angeordneten Mikrowellenempfänger derart zugeführt ist, daß Sender, Mikrowelle und Empfänger einen Bewegungsdetektor bilden, der den Sicherheitsschalter steuert.In the improvement of machines as specified in the introduction Design is proposed according to the present invention that at the head of the machine stand on each A microwave transmitter is arranged on the three free access sides of the machine, the microwave radiation of which is transmitted covers the access area and over the installation area the machine is fed to a microwave receiver arranged on the head of the stand in such a way that it reflects is that the transmitter, microwave and receiver form a motion detector that controls the safety switch.
Die Anordnung kann bevorzugt auch derart getroffen sein, daß Tür die drei Zu.rriffsf lachen der Maschine ein am Kopf der Maschinenständers befestigter gemeinsamer Bewegungsdetektor vorgesehen ist. The arrangement can preferably also be made in such a way that a common motion detector attached to the head of the machine frame is provided in the door of the three access areas of the machine.
Die vorgeschlagene Anordnung bietet den Vorteil, daß bepondere zusätzliche Umlenk- und Führtmgsel emente für dieThe proposed arrangement has the advantage that bepondere additional deflection and guide elements for the

Fig. 2 zeigt eine Funkenerosions-Senkmaschine zur Senkbearbeitung metallener Werkstücke.Fig. 2 shows an electrical discharge machine for countersinking metal workpieces.
In Fig. 1 bezeichnen 1 den Sockel der Maschine, der auf einer Aufstellungsfläche z.B. auf Beton aufgestellt ist. Sein aufrecht stehender Ständer trägt einen Ständerkopf k, der den Sockel 1 teilweise übergreift und über einen (nicht näher dargestellten)Antriebsmechanismus einen U-förmigen Bügel 5 durch einen Rechner gesteuert in der Horizontalebene nach zwei Koordinaten verstellt werden kann. Er trägt als Bearbeitungswerkzeug eine drahtförmige Erodierelektrode 6, die als Bearbeitungselektrode an eine elektrische Spannungsquelle angeschlossen ist, die eine impulsförmige Arbeitsspannung einstellbarer Frequenz erzeugt. Die Elektrode 6 dien.t zum funkenerosiven Schneiden einer Metallplatte 7» die in einer (nicht dargestellten) Einspannvorrichtung in einem Dielektrikumsbehälter 8 gelagert ist. Der mit einem flüssigen Dielektrikum, z.B. Petroleum, gefüllte Behälter 8 ist auf dem Sockel 1 auf einem Holztisch gelagert und nach zwei Koordinaten in der Horizontalebene verstellbar. In Fig. 1, 1 denotes the base of the machine, which is set up on an installation surface, for example on concrete. Its upright stand carries a stand head k, which partially overlaps the base 1 and a U-shaped bracket 5 can be adjusted by a computer controlled in the horizontal plane according to two coordinates via a drive mechanism (not shown). As a machining tool, it carries a wire-shaped eroding electrode 6 which, as a machining electrode, is connected to an electrical voltage source which generates a pulse-shaped working voltage of adjustable frequency. The electrode 6 is used for spark erosion cutting of a metal plate 7 which is mounted in a clamping device (not shown) in a dielectric container 8. The container 8 filled with a liquid dielectric, for example petroleum, is mounted on the base 1 on a wooden table and can be adjusted according to two coordinates in the horizontal plane.

Das Gehäuse des Senders Io nimmt gleichzeitig entsprechende Mikrowellenempfänger auf, die den drei Seiten 11, 12, 13 zugeordnet beim Eingriff des Bedienenden in den Mikrowellenvorhang ein Schaltsignal· erzeugen, das den elektrischen Impulsgenerator der Maschine abschaltet. Gleichzeitig werden die Antriebsfunktionen der Maschinen, d.h. die Verstellung des Kreuztisches, die über elektrische Antriebsmotoren erfolgt, und die Verstellung der drahtförmigen Erodierelektrode 6, die ebenfalls über entsprechende Antriebsmotoren erfolgt, stillgelegt.Op len radiation that tightly covers the hazardous areas and reflected on the installation surface 2 towards the transmitter Io is returned. The housing of the transmitter Io takes at the same time corresponding microwave receiver that the three sides 11, 12, 13 assigned to generate a switching signal when the operator intervenes in the microwave curtain, which switches off the electrical pulse generator of the machine. At the same time, the drive functions of the machines, i.e. the adjustment of the cross table, which takes place via electric drive motors, and the adjustment of the wire-shaped erosion electrode 6, which also has corresponding Drive motors takes place, shut down.
Durch Druckknopfbetätigung läßt sich die Maschine - nach Beseitigung des Eingriffs - wieder in Betrieb setzen.The machine can be opened by pressing a button - after removal of the intervention - put it back into operation.

Der Dielektrikumsbehälter 8 nimmt wieder ein (nicht dargestelltem) Werkstück auf, das mittels einer Bearbeitungselektrode 2o die mittels eines im Ständerkopf k angeordneten Antriebsmotors in vertikaler Richtung verstellbar ist, bearbeitet werden soll. Der Dielektrikumsbehälter 8 ist wiederum mittels eines Kreuztisches, der auf dem Sockel 1 angeordnet ist, motorisch nach zwei Koordinaten in der Horizontalebene positionierbar. In Fig. 2, 1 again designates the base of the machine, 2 the associated installation surface, 3 the upright stand and k the stand head of the machine. The dielectric container 8 again receives a workpiece (not shown) which is to be processed by means of a processing electrode 2o which is adjustable in the vertical direction by means of a drive motor arranged in the stator head k. The dielectric container 8 can, in turn, be positioned by a motor according to two coordinates in the horizontal plane by means of a cross table which is arranged on the base 1.
