Das Tieflochbohrgerät nach Anspruch 1, bestehend aus den obengenannten Pos. 1-11, arbeitet mit einem Leitstrahl- Steuerungs-System, automatisch selbstzentrierend gemäß nachfolgender Beschreibung:The deep hole drilling machine according to claim 1, consisting of the above items 1-11 , works with a beacon control system, automatically self-centering according to the following description:

Zum Beginn des Bohrvorgangs wird der Bohrkopf zum Werkstück gefahren. Zum Ansetzen des ersten Schnitts wird das Drucklager (8) vor Bohrbeginn zur Stabilisierung durch 2 Halbschalen abgestützt, solange sich das Drucklager außerhalb der zu fertigenden Bohrung des Werkstückes befindet. Auch bereits in dieser Stellung kontrolliert und regelt das Tieflochbohrgerät bereits seinen Bohrkopf ins Zentrum der optisch geraden Soll-Achse der Bohrung. Funktionsablauf: Der vom Laser ausgesandte Leitstrahl (10) löst beim Auftreffen auf ein beliebiges Meßfeld des Lichtelements (5) in der Steuereinheit (11) eine Funktion aus, durch die, mittels der Hydraulikzylinder (7) das Zentrum (9) der Lichtelemente mit dem Laserstrahl zur Deckung gebracht wird. Das als Empfänger wirkende Lichtelement setzt sich aus vielen kleinen Einzelelementen zusammen, welche kreisförmig um das Zentrum herum in Ringsektoren angeordnet sind, von denen jeder einzelne mit dem, von ihm zu beeinflussenden Steuerbereich verbunden ist. Unabhängig von mechanischen und hydraulischen Faktoren hält die Tätigkeit der Steuerung so lange an, bis der Laserstrahl und das Zentrum der Lichtelemente in Deckung stehen. Damit ist die gestellte Aufgabe erfüllt. Neu auftretende Verlagerungen werden auf die gleiche Weise bereits im Feinbereich nachgeregelt.At the start of the drilling process, the drill head is moved to the workpiece. To make the first cut, the thrust bearing ( 8 ) is supported by 2 half-shells for stabilization before the start of drilling, as long as the thrust bearing is outside the hole to be made in the workpiece. Even in this position, the deep hole drilling machine already controls and regulates its drill head in the center of the optically straight target axis of the hole. Functional sequence: The guide beam ( 10 ) emitted by the laser triggers a function when it strikes any measuring field of the light element ( 5 ) in the control unit ( 11 ), by means of which, by means of the hydraulic cylinder ( 7 ), the center ( 9 ) of the light elements with the Laser beam is brought to congruence. The light element acting as a receiver is composed of many small individual elements which are arranged in a circle around the center in ring sectors, each of which is connected to the control area to be influenced by it. Regardless of mechanical and hydraulic factors, the control system continues to operate until the laser beam and the center of the light elements are aligned. The task is now complete. Newly occurring relocations are readjusted in the same way in the fine area.
