The basic construction consists of a stable welded steel frame and a protective enclosure made of aluminium profiles with polycarbonate glazing. The dynamic drive of the coordinate axes via recirculating ball screws with servo motors and motion control allows a high traversing speed. Stable C-frames are used for fastening the riveting units. Since 1984, the CNC riveting machine control has been characterised by freely parameterisable riveting programmes. The current CNC control with high-resolution multi-touch display, optional process data acquisition and various interfaces enables easy operation of the machine and thus continues this tradition. Coordinate axes with an X/Y riveting range from 280x180 mm to 350x500 mm are available as standard. All hydraulic and pneumatic FMW Friedrich riveting machines and units can be used for the riveting process.
