Retrofit

After some years of productive use, even a well-maintained machine needs to be overhauled or modernized. Since quality requirements and rationalization measures are constantly increasing, it is not enough to “just” update the existing machine tool. When changing the given parameters or expanding the machine with new components, you also have to constructively reevaluate and redesign its concept. With these measures, we often achieve more efficiency than with a standard new machine. Therefore, a retrofit of your old machine is often an economic alternative to purchasing a new machine.

Type PFH 75

This new slider featuring an angular milling head can be applied both horizontally and vertically. This slider and angular milling head are the main reason for the machine's increase in performance from 60 to 135 kW. For this, we widened the gap between guideways on the crossbeam. By combining this redesign with the existing components, we achieved a significant performance increase. We built in new electrical equipment with a Siemens control system as well as an additional tool changer and a pick-up-station for additional angular heads, all of which led to the machine being significantly more efficient.
