The notching process is one of the cheapest methods to grant the interference between shaft and lamination stack and / or shaft and commutator. Dema has designed and developed a machine whose name is “Shaft Cut” that could be stand-alone or integrated in line. This machine is a full automatic station for cutting rotor shafts. It is not only able to perform the notching function but it also guarantees process quality, high reliability and simplicity of configuration and regulation.
The advantages are: cheaper machining cost (thanks to the fact that it is no more necessary to buy cut shafts from suppliers) , process stability in time (because in case of variations any corrective intervention would be done immediately) and then high coupling repeatability of shaft/lamination stack coupling, as well as a very high reduction of possible rejects.
