This CNC portal milling machine is designed for the machining of hard materials as well as aluminum. With its solid cast base, 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 allows up to 16 metric tons of table load. Eight mounting elements of the FZ40 compact reduce vibration – the basic requirement for high accuracy and optimum surface quality of the work pieces.
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 combination of high strength and rigidity, constant moving masses and dynamic drives, will meet the industries high demands.
This design ensures outstanding temperature stability and posses- ses integrated oscillation and vibration damping for even greater milling precision. The A-axis is powered by a zero-play torque drive package, and the C-axis is powered directly by a torque motor. A liquid cooling system dissipates the heat from simultaneous machining. Both heads are suitable for milling aluminum, composites, steel and cast iron.
The integrated vibration and vibration damping ensures maximum surface quality and cutting performance. Due to the backlash-free drive, the 2-axis milling head achieves precise positioning and repeat accuracy. Suitable for HSC machining of aluminium, CFRP and GRP, achieves a maximum performance in volume cutting.
The drives, which incorporate zero-play torque motors, ensure outstanding dynamic behavior and maximum material removal rates in the machining of different materials. This extremely efficient milling head features a flexible MuST® spindle change system for precise execution of complex milling jobs. Roughing and finishing of various workpieces can be carried out without reclamping, which considerably reduces setup times.
