Thread Forming & Tapping

Precise Tapping in Automated Mass Production

The integration of thread forming processes in a fully-automated manufacturing solution on a stamping and forming machine offers users the possibility to join complex components together using screws. In this process, the thread is produced by forming the material 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 is 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, because the material structure is not damaged.

Advantages of Bihler tapping units:

  • Production speeds of up to 260 threads/min.
  • Rapid retooling system for shortest possible setup times
  • Increase of tool life up to 50%
  • Wide range of applications and easy handling
  • Units can be integrated in any manufacturing concept
  • GSE K: Flat design for use in presses and / or where tool installation height is low
  • GSE KS: Narrow design for use in restricted spaces
