TAPPING - MANUFACTURING TECHNOLOGY FOR STAMPED AND FORMED METAL PARTS

Precise tapping in automated mass production

The integration of thread forming processes in fully-automated manufacturing solutions on stamping and forming machines offers users the possibility to join complex components with screws. In this process, the thread is produced through non-cutting forming of the material to be machined using the servo-controlled GSE thread forming unit. In the prefabricated punched hole, the material is pressed to the side by the edges of the thread former and thrown up to form a burr. After multiple revolutions of the thread former, the burr takes the form of grooves.

The thread forming process is particularly well suited for materials with good formability and low tensile strength. With more robust tools, threads with smooth surface, high strength and high load resistance can be formed with the highest precision, since the material structure is not damaged.
