6. Punching inside / outside



Punching is based on the principle that a narrow punch (die) is positioned inside the tube and then the tube is fixed around the punch with 2 split tool halves. A cutting punch is then pressed very precisely onto the outside of the tube below the cutting punch hole at high speed and force, creating a hole. The tubes are fed in using a servo motor and the tube can be punched several times within one cycle. The systems are equipped with a punching hole control, which ensures that the quality of the output product is guaranteed. There are also DMC readers on the system for data transfer and quality control of the end products.
