OTEC
The quality of stamping, forming and cutting tools can be improved considerably by finishing the workpieces in DF and SF machines from OTEC. Defined edge rounding dramatically increases the life of cutting tools, as a rule by a factor of three. The OTEC process not only rounds the edges but also smooths the surfaces considerably. This significantly reduces chipping and improves chip flow. The friction acting on PVD and DLC coated workpieces can be reduced dramatically by means of a short finishing process which thereby significantly reduces wear. With forming tools, Ra values of up to 0.02 µm can be achieved and the percentage of contact surface greatly increased. Special polishing processes largely prevent corrosion at the tool holder, so that no further anti-corrosion treatment is needed for several months.
