Advantage of the portal design

Portal milling machines are masters of versatility. Moving masses are extremely low, above all facilitating machining of large workpieces. Whereby 5-sided, 5-axis machining helps to mill even complex shapes from a block of material in just a short time. The construction reduces any vibrations which occur to a minimum, permitting high dimensional accuracy and surface finish as well as maximum machining performance to be achieved. For anyone aiming at optimal machining results, the portal is the gate to success!

 

 

5-axis machining

5-axis machining permits optimal milling of even the most complex contours.

Large side-steps can be achieved using toric tools, resulting to good surface finishes and considerable time savings.

 

 

5-sided machining

5-sided machining makes it possible to machine even complex and large parts in a single setup.

This leads to greater precision and reduces throughput time.

 

Structural stiffness

Portal milling machines from Zimmermann are characterized by the high structural stiffness of the side columns. This is achieved through the use of fibre-reinforced materials, leading to good vibration damping and thermal stability of the machine.

 

 

Low moving masses

Advantages are also derived from the FEM calculation of the portal structure. Thus, by taking the dynamic behaviour of the machine into account, optimal structural rigidity can be obtained. Only a small mass needs to be moved, the stability is still maximized. Efficient machining is the result.

 

 

Individual working areas

When defining working areas within the portal milling machine, creativity knows hardly any limits. Zimmermann has already implemented various clamping table concepts, integrated partition walls, tandem or duo versions and a variety of pallet changers.

 

 

Control systems

The right control system for each application scenario – with an adaptive software concept and the support of control systems from leading manufacturers, Zimmermann offers maximum flexibility in this area.
