DEVICE FOR SEQUENTIAL DIAMOND-ABRASIVE AND FINISHING-STRENGTHENING PROCESSING OF PARTIAL SPHERICAL SURFACES Russian patent published in 2008 - IPC B24B39/04 

FIELD: technological processes.

SUBSTANCE: device contains individual drive with spindle with deforming element, helical cylindrical spring, which is wound with one end and rigidly fixed at spindle, and cartridge with slots, which is rigidly fixed on the other end of helical cylindrical spring. Device is made based on condition of its longitudinal axis passing through the center of processed spherical surface of preform and installation of the axis at the angle to the plane that is perpendicular to longitudinal axis of preform. Deforming element is arranged in the form of ring, on the ends of which on its internal surface deforming part is installed in the form of toroidal surface and diamond-abrasive part in the form of truncated cone with diamond-abrasive layer. Two transverse axles are arranged on the external surface of ring, by means of which ring is installed in slots of cartridge with the possibility of deforming part or diamond-abrasive part turning to preform.

EFFECT: technological resources are expanded; efficiency, quality and precision of processing are increased.
