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 possesses 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. 

Experience how close maximum mechanical accuracy comes to perfection. From portal milling machines in classic design to 5- and 6-axis gantry milling machines and horizontal machining centers, all Zimmermann milling solutions guarantee the highest quality and precision.

Our milling solutions make use of the optimum drive for the machine concept in question. The extremely dynamic and particularly low-maintenance rack-and-pinion drive provides excellent performance at a reasonable cost. All imaginable axis lengths are possible and cover an extremely wide range of applications. The classic among the drive designs is the ball screw drive. It is characterized by its high precision, low cost and outstanding economic efficiency. The linear motor is the ideal solution for applications involving largely stationary masses.
