Abstract of the Disclosure The spinning rotor is made from steel for an open end spinning machine and is provided with a thinwalled rotor wall with a fiber collecting groove and a locally limited hardened zone (11) comprising the fiber collecting groove at the largest inside diameter. Due to the partial hardening of the rotor wall, high wear resistance is achieved for the fiber collecting groove while the finished shape and roundness of the spinning rotor made from unhardened steel is maintained.
