The automatic machine is designed, so that length set-up is done once, and is already affecting all stations. Save floor space by using one machine, that takes further less floor space then 2 or 3 machines traditionally needed to manufacture the same product. Less in-process expensive material that requires floor space, and is subject to damage. No risk of mixing materials. The customer keeps track on the material coming into the machine Save power.
Less power is required for a fully automatic machine, compared to a few semi automatic machines.
Take advantage of the position of the part. For example, in a wheel bolt thread roller, the parts come out of the first station already oriented, ready for the next station. Rolling rather than cutting The industry is leaning toward rolling shapes that used to be cut. The reason is not only for the higher quality and better consistency, but also for saving material and achieving faster speeds. Rolling chamfers by the Videx chamfer system, for example, is extending the blanks by 1.5-3.0mm, which is a considerable saving in raw material.
