Abstract
The spinning system according to the present invention performs spinning properly, by driving a working tool in revolution, on an unrotatably supported member to be machined, and also performs other work such as cutting, etc. after the spinning. For that purpose, the spinning system according to the present invention comprises a first rotor (24) provided at the tip of the outer tube (21) and a second rotor (25) provided at the tip of the inner tube (23), forms a first guide route (guide groove (25a)) and a second guide route (guide groove (25b)) on this second rotor (25), and movably supports a first working tool (roller (28)) and a second working tool (cutter blade (30)) respectively, on the first rotor (24), along those first and second guide routes, to rotatably drive the outer tube (21) and the inner tube (23) in one same direction, on an unrotatably supported member to be machined (tube material (4)), and rotatably drive them relatively, as required, in a way to produce a difference of rotation between the two.
