METHOD TO PROCESS NON-ROUND HOLES Russian patent published in 2014 - IPC B23B35/00 B23B41/04 

FIELD: machine building.

SUBSTANCE: invention refers to machine building and can be used in bearing industry at processing of the hole edges in big bearing cages. The method implies imparting of shaping motions to profiling heads with cutters in respect to the part being processed along with matching the axes of the profiling heads' templets and the hole being processed. The part being processed is rigidly and horizontally fixed on at least three supports evenly distributed along its end face circle. The cutters are installed along the axis parallel to the symmetry axis of the hole being processed on the internal and external sides of the part being processed, located at the said part in respect to the said hole and fixed on it to perform processing. Afterwards the cutters are unfastened and slided along the end face of the part being processed by an angular pitch of the next non-round hole position for processing.

EFFECT: reduced overall dimensions of a device, profiling heads with cutters and area of production premises, manual labour is excluded.
