The chief innovative concept of the system is based on the criterion of conveying metal chips through a straight collector tube impelled by a rotating screw operating along the entire lenght of the tube. ADVANTAGES: versatility; adaptability to any chipping morphology (dust, short metal chips and long tangled ribbons).; labour savings as no worker is needed to remove metal chips; compaction of conveyed metal chips the degree of compaction of the chippings correlates with their morphology, with consequent reduction in volume.; high conveying efficiency thanks to the considerable reduction in the specific volume of metal chips and continuous running.; forced flow introduction of material into container-compactors for initial storage.; less external space needed outside the machine tool.
