NC Fanuc press with planetary roller screw
The G3 Press revolutionises the world of cutting with its special motor and planetary roller screw drive concept. This principle allows innovative fast, flexible and precise programming of cutting or sharpening cycles using the "Fanuc Power Motion i-model A" control and its touchscreen. The tooling moves by means of a planetary roller screw which allows each step of the cutting or sharpening cycle to be configured in detail. The strip is powered by an efficient motorised system, mounted directly on the frame, with automatic control of the feed depending on the strike speed.
The cast iron base of the G3 Press, on "Silentbloc" mounts, gives it a great deal of stability making for a particularly quiet machine on which the operator can enjoy a comfortable seated work position due to the hollow frame, the armrests and to the motorised safety protection. For added safety, the "double part" check stops the cycle if the cut part has not been removed, therefore preventing overlapping of parts and damage to the tools.
