Abstract |

[DE] Die vorliegende Erfindung betrifft ein Verfahren zur Erzeugung von Schraubgewinden in Werkstoffen mittels einem, eine Drehbewegung erzeugendem Werkzeug, wobei durch einen oder mehrere rotierende Bohrer mit einem kegelförmigen endständigen Schleifrad, das um seine eigene Achse rotiert, sowie um eine weitere zur Drehachse des Schleifrades parallele in einem variierbaren Abstand von dieser befindliche zweite Achse planetenartig gedreht und dabei in Richtung des Werkstückes bewegt wird, gegebenenfalls unter Zugabe einer Flüssigkeit, Suspension oder Paste mit Hartstoffen, Schraubgewinde mit vorgegebenem Durchmesser und vorgegebener Steigung in einem Arbeitsgang erzeugt werden.
[EN] The present invention relates to a method of producing screw threads in materials by means of a tool producing a rotary movement, in the course of which screw threads of predetermined diameter and predetermined pitch are produced in one operation by one or more rotating drills with a tapered end grinding wheel which rotates about its own axis as well as in a planetary manner about a further second axis, parallel to the axis of rotation of the grinding wheel and located at a variable distance from it, and in the process is moved in the direction of the workpiece, if need be with the addition of a liquid, suspension or paste with mechanically resistant substances. <IMAGE> |
