Hollow motor shaft
It is possible to reduce the diameter at both ends of the pipe and form a flange at the reduced diameter section. Since it can be formed from thick-walled pipes without cutting, and can achieve flange formation through plastic processing, it allows for a reduction in material costs. Compared to forging, this process involves less cutting and does not waste resources. It contributes to carbon neutrality and the SDGs.
By elongating the end of the material shaped by forging, it is possible to extend the forming limits of forging.
In the molding of long and hollow shafts, it is possible to utilize existing forging equipment. Sequential molding using spinning machines raises the limits of forging. Mass production of shafts that could not be molded due to stroke limitations becomes possible. Because it is sequential molding, entry into new products can be achieved with low equipment investment.
