    摘要： The invention relates to a method of making a thread or tap on a cylindrical, conical or frustoconical piece to be machined.
    According to the invention, this method comprises the steps of: a) driving in rotation the piece to be machined in one direction), b) carrying out a relative displacement of a first cutting edge of a tool relative to the piece to be machined until this first cutting edge is flush with the surface to be threaded of the workpiece at the beginning of the section to be threaded, c) carrying out a relative displacement of the tool relative to the piece to be machined so that the first cutting edge machines the piece to be machined, d) carrying out a relative displacement of the tool along the longitudinal axis of the piece to be machined, in one direction until the end of the section to be threaded, e) moving away, by a relative displacement, the first cutting edge of the tool from the piece to be machined, and it has the particularity of further comprising the steps of: f) reversing the rotation of the piece to be machined to drive this piece in rotation in the direction opposite to the direction, while positioning or not the second cutting edge, g) moving, by relative displacement, a second cutting edge towards the piece to be machined until this second cutting edge penetrates the thread pitch, h) carrying out a relative displacement of the second cutting edge relative to the workpiece so that it continues the machining of the thread in the piece to be machined, i) carrying out a relative displacement of the second cutting edge in a direction opposite to the direction, until the beginning of the section to be threaded, j) moving, by a relative displacement, the second cutting edge away from the workpiece to be machined, k) reversing the rotation of the piece to be machined, while positioning or not the first cutting edge then l) repeating steps b) to k), while continuing the machining of the thread, until the thread reaches its final dimensions, while positioning the first cutting edge in step b) in such a way that it penetrates the thread pitch already machined.

    摘要： A die stock comprising a substantially cylindrical holder, which is symmetrical to a centric holder longitudinal axis that runs in an axial direction, wherein the holder has a plurality of receiving grooves each of which is configured for receiving a cutting insert and a clamping wedge, wherein each of the receiving grooves extends from a first end face of the holder in the axial direction, said first end face running transversely to the axial direction, and wherein each of the receiving grooves extends from an inner side of the holder in a radial direction, said inner side facing toward the holder longitudinal axis. The die stock further comprises a plurality of cutting inserts arranged detachably in the receiving grooves, wherein each cutting insert has, on a front side that faces substantially toward the holder longitudinal axis, at least one cutting edge. The die stock further comprises a plurality of clamping wedges arranged detachably in the receiving grooves in order to axially and radially fix the cutting inserts, wherein one clamping wedge and one cutting insert is provided for each of the receiving grooves, respectively, wherein the clamping wedges are, in a peripheral direction that runs transversely to the axial direction and the radial direction, arranged alongside the cutting inserts in each of the receiving grooves, respectively. Still further, the die stock comprises one holding means per receiving groove, for fastening the clamping wedges and cutting inserts in the receiving grooves.

    摘要翻译： 一种模具坯料，其包括基本上圆柱形的保持器，其与沿轴向延伸的中心保持器纵向轴线对称，其中所述保持器具有多个接收槽，每个接收槽被构造成用于接收切削刀片和夹紧楔，其中 每个接收槽从保持器的轴向方向的第一端面延伸，所述第一端面横向于轴向延伸，并且其中每个接收槽沿着径向方向从保持器的内侧延伸， 所述内侧面朝向保持器纵向轴线。 模具坯料还包括可拆卸地布置在接收槽中的多个切削刀片，其中每个切削刀片在基本上朝向保持器纵向轴线的前侧上具有至少一个切削刃。 模具坯料还包括可拆卸地布置在接收槽中的多个夹紧楔，以便轴向和径向地固定切削刀片，其中分别为每个接收槽提供一个夹紧楔和一个切削刀片，其中夹紧楔 在横向于轴向方向和径向方向的圆周方向上分别沿着每个接收槽中的切削刀片布置。 此外，模具坯料包括每个容纳槽的一个保持装置，用于将夹紧楔块和切削刀片紧固在接收槽中。
