螺纹，特别是内螺纹的生产包括在最初在周边部位上插入工件（16）开口之后，将具有轮廓突起（20）的刀柄（10）在螺纹的头部（18）上径向放入工件中 的开口并执行360度相对圆形运动，同时保持旋转轴线的偏心度（EX），同时螺纹头部还执行对应于螺纹间距的恒定轴向相对向前移位运动（BV） P）。 还包括用于生产线程的工具的独立权利要求。

Described is a tool for the production of threads, in particular of internal threads that allows a manufacturing process in which the inner surface (16) is machined of a workpiece bore by means of non-cutting pressure deformation. The tool has a forming head (18; 118) with at least two trained after the manner of a thread mill and in a constant axial distance (T) to each other profile projections (20) around the circumference throughout and with circumferentially varying radial extent (ERMIN , ERMAX) are formed, so that in the region of each profiled projection (20) over the circumference of at least one pressing lands (22; 122) is formed. The profile projections (20) form with the circumferentially changing radial extent (ERMIN, ERMAX) over the circumference each more pressing lobes (22; 122) from. The pressing lands (122) of adjacent profile projections are offset from one another in the circumferential direction. To thread of different nominal diameter to be able to produce in the region of the thread particularly economically and with improved fabric quality, the thread is formed in that the tool is initially retracted at a peripheral location of the workpiece bore into the workpiece, preferably is brought to full thread depth, and while maintaining the set to the axis of the workpiece bore eccentricity of the rotation axis performs a 360 ° continuous relative circular movement (circular movement) with respect to the axis of the workpiece bore, while the shaping head simultaneously performs a constant axial relative advancing movement by the dimension of the manufactured Gewindsteigung.
