If one decides already at the point of the purchase – for a rather small extra charge – for an accordingly larger system, one is on the safe side for further extensions. The system can then be equipped either right from the start or later with more than one spindle. Compared with several smaller systems (which have the same total working area) there is a price advantage and less space required in the production hall.

Thus Frank Benzinger, vhf managing director, advises not to choose a basic system which is too small: “Often one does not observe at the moment of the purchase what a great increase of efficiency such a small additional charge can mean for the serial production.” The large working areas of vhf engraving and milling systems, which amount up to 2 x 4 m, offer a large potential to process many workpieces at once.

For instance, if three spindles are used at the same time, the working time will be reduced to less than one third in comparison to a system that has only one spindle. The reason for this is that additional positioning moves become obsolete. The gain of productivity is the higher, the more spindles can be used at the same time. The control electronics allow to switch all spindles simultaneously by software and to regulate their rotational speed. Generally, all spindles offered by vhf can be used for multi-spindle solutions.
