METHOD OF TURNING TREATMENT Russian patent published in 2009 - IPC B23B1/00 

FIELD: technological processes.

SUBSTANCE: method consists in the fact that rotation with cutting speed is imparted to part, and feed motion is imparted to double-blade cutter. In order to increase efficiency of treatment, tops of cutter blades are installed higher and lower than axis of part rotation symmetrically relative to it. Treatment may be carried out at least in two cuts, at the same time return cut is executed with cutting feed. Part rotation may be varied to an opposite one in process of cut or in case of cut changeover.

EFFECT: improved efficiency.
