The invention relates to methods for producing a thread with a predetermined thread pitch in a workpiece.

Methods and device for producing a thread, comprising a gear unit

A drilling tool for producing a bore with a cylindrical inner wall can be rotatable in a rotary movement with a predetermined rotational direction (VD) about a tool axis (A) extending through the drilling tool, and at the same time is movable in an axial forward movement (VB) in a forward direction axially to the tool axis. The drilling tool comprises at least one drilling area () arranged in a forwardly located region of the drilling tool at a forward or free end, but preferably not having a thread forming region. The drilling area has a number n of drilling edges which are arranged offset to each other in the rotational direction, and at least one chip divider is arranged on at least one or each of the n drill cutting edges, where the chip divider forms an interruption of the respective drill cutting edge.

Drilling tool and method for producing a borehole

A thread forming tool comprises a thread generating region that extends along a helical line with a thread pitch angle and a thread direction of the thread to be formed and has an active profile corresponding to the thread profile of the thread to be formed, wherein the thread generating region has a thread tooth having a thread profile with a front thread tooth profile flank and a rear thread tooth profile flank, has a front flank relieved surface, adjoining the front thread tooth profile flank and has a rear flank relieved surface, adjoining the rear thread tooth profile flank, wherein the front flank relieved surface is isolated relative to a front thread tooth flank envelope, wherein the rear flank relieved surface is displaced relative to a rear transverse plane wherein the helical line is inclined to the rear relative to the rear transverse plane by the thread pitch angle.

Tool and method for forming a thread, in particular an internalthread

A method for forming a thread with a predefined thread pitch and with a predefined thread profile in a workpiece, in which a tool is used, wherein, during working movement, a thread generating region forms a thread, wherein the tool is moved during a second working phase further into the workpiece in the same forwards direction as in the working movement, as far as a reversal point, wherein the decelerating movement comprises a rotational movement in the same rotational direction as in the working movement, wherein during the decelerating movement, the axial feed movement is controlled in dependence on the rotational angle of the rotational movement of the tool and wherein the axial feed of the tool during a complete revolution, is smaller in terms of amount than the thread pitchat least during part of the decelerating movement and is zero at the reversal point.
