How it works

The driving motor of the die head sends RPM data to the PLC computer to calculate the correct RPM for the motor powering the ball screw for the selected thread pitch. The PLC computer monitors and corrects the RPM of the ball screw during operation if necessary. The material thereby exhibit significantly more accurate thread pitch than material that has been threaded in a manual machine or with a threading chaser. The optosensors on the die head protection cover signals when the material reaches the dies in order to achieve the exact thread length. Cooling fluid is sprayed on cutting surfaces during threading. When the thread length is reached, the cooling spray ceases, the die head opens and the carriage is fed back to the loading position. If the carriage unintentionally moves to close to the die head, the die head opens automatically.
