DEVICE FOR FINISHING TREATMENT OF SPHERICAL SURFACE Russian patent published in 2009 - IPC B24B39/04 

FIELD: mechanics.

SUBSTANCE: device contains casing and located in it operating tool, firing-pin and waveguide, which is implemented with ability of application to it of periodic pulsed load by means of firing-pin. Casing is implemented with radial grooves, stepped hole and with ability of rotation from individual drive. Operating tool is implemented in the form of bundles of metallic fine wires pile, V-shaped bended inside the casing with formation of working concave spherical surface. Pile bundles are installed on butt of casing in its radial grooves and are implemented in the form of cutting or deformation element. Wave guide is located in stepped hole of casing from the condition of providing of additional movement of metallic fine wires pile and its straightening with creation of additional interference at influence of periodic impulsive load.

EFFECT: manufacturing capabilities are expanded, it is increased productivity, and reduced costs.
