Compact Milling Machine Enhances Performance and Accuracy

The CNC portal milling machine FZ40 compact from Zimmermann is designed for the machining of hard materials and aluminum. The inherently rigid machine structure enables simultaneous five-axis high-speed machining. This compact machine has a solid cast base so it does not require a foundation and can be set up on any solid shop floors. The machine table is integrated into the cast baseplate, which enables a table load ranging to 16 metric tons.

Eight mounting elements of the FZ40 compact reduce vibration for high accuracy and optimum surface quality of the workpieces. In addition, the sidewalls are filled with a special dampening concrete mix to further enhance performance. The machine has a fully enclosed working space with a fixed machine table. The structural sound overhead gantry with a reinforced Z-ram make up the moving masses.

The machine’s dynamic two-axis VH60 milling head is very temperature-stable because of the cast monolithic fork design. Furthermore, oscillation and vibration dampening are reduced to a minimum to ensure even more precise machining results. The machine is capable of 102 kW (137 Hp), up to 575 Nm (424 ft lb) of torque and HSK A 100. The backlash-free drives achieve a precise positioning accuracy and repeatability in the A- and C-axis. The milling head is designed for high-speed machining of tough materials such as steel, titanium and aluminum.
