FRANKEN introduces the new Alu-Jet-Cut line, a tool line of radically new solid carbide end mills for the large-volume machining of aluminium materials with a silicon content of up to 6%. Due to the combination of an optimum carbide substrate with a newly developed cutting geometry and optimised grinding processes, machining volumes which would have been considered impossible until now can be achieved with the Alu-Jet-Cut.

One of the target markets for this new tool type is the aircraft and space industry. Some of the components which are produced in this industry lose up to 95% of their original weight, all through machining processes. Time is one of the most important factors under such circumstances, and it is defined by the machining volume produced, and measured in litres per minute.

In the course of extensive tests, machining volumes were achieved which will set new standards. Especially important is chip evacuation which until now decided the limits of the possible machining volume.
Now, the limits are defined only by the performance of the machine spindle, provided that work conditions are otherwise as good as they can be. The available torque in the higher speed ranges is the relevant factor here.
