The precision tool manufacturer Simtek is venturing into the field of hard metal with the laser. Laser-cut chip shape geometries are a minor revolution for the production of tools for metal cutting. What previously seemed impossible has now been proven in numerous projects. An interview with the board and experienced tool developer Norbert Seifermann.

Mr Seifermann, since when has chip removal played such an important role in metal cutting?

Norbert Seifermann: Ever since metal machining began, the focus has been on optimal chip removal. This is certainly not yet so relevant in our training workshop, where our apprentices are first taught to get a feel for the chip using a file and tap wrench. They then sweep or blow away their few chips with a broom or compressed air. This changes as soon as the CNC machine is used. In machining, the person who breaks the chip best and brings it under control achieves better production results. In the end, this pays off for the user in many ways through increased process reliability, higher cycle rates, longer tool life and, ultimately, lower costs.
