With the FZ100 portal milling machine Zimmermann has managed to achieve 6-axis machining using the newly developed M3 ABC 3-axis milling head. This concept sets new standards in the volume machining of aluminium, composite and model making materials as well as in the high speed cutting of steel and cast iron, where conventional 2-axis fork heads with A- and C-axis have long reached their limits in the 5-axis simultaneous machining.
