The application of cooled air helps to reduce temperatures in the cutting area which in turn permits higher cutting speeds and increases tool life. This type of cooling will bring out the full advantages of modern coatings, because the cutting edge can no longer be damaged by thermal shock.
The function of the cold-air Nozzle is based on the principle of the vortex tube, in which two opposed, rotating air streams are generated (without any moving components). The internal air stream exits from one end, in the form of useable cold air with a temperature up to -30°C. The only thing that is needed is a normal pressurized air connection.
