The mechanical structure is based on a main steel traverse beam, a longitudinal light alloy beam and a vertical axis in aluminium, on which are mounted the hard quenched steel prismatic rail runways for the re-circulating ball bearings resulting in very low friction. Movements are powered by brushless servomotors, controlled by an incremental reader which is coupled to a epicyclical gearbox with limited backlash The transmission is through rack and pinion with angled teeth or through toothed belt. Larger models are equipped with a pneumatic closed loop compensation system on the vertical axis. Vertical axes come in both fixed and telescopic movement, and for low headroom applications a triple-scopic version is available.
Each model can be supplied with Euromap 67 interface or an interface that is fully integrated with the Negri Bossi machine control system.
The Flash Sy robots can be customised to suit the end users application with a wide range of optional equipment: standard or special modular pick up systems, additional vacuum circuits, adjustable wrist pneumatic rotations 0°-90°/0°-180°, servo driven wrist rotations 0°-320°, additional I/O modules.
