OSCILLATING NEEDLE HOB FOR PROCESSING OF PLANES Russian patent published in 2011 - IPC B23C5/00 

Abstract RU 2428283 C1

FIELD: process engineering.

SUBSTANCE: proposed device comprises need hob to be fitted in machine tool spindle that comprises body with bundles of wire frieze secured thereon. Blunt holes are bored in body face at acute angle β making 0<β<45° to lengthwise axis. Note here that rods are fitted in said bores to slide therein. Note also that needle holders are fitted on rod outer spherical faces to act on processed surface by bundles of wire frieze clamped in needle holders as well as packages of plate springs acting on rod inner faces to create operating pressure. Besides, said body may reciprocate and oscillate relative to lengthwise axis to allow needle holders to oscillate and reciprocate radially. Note that said needle holders are interconnected by helical compression springs.

EFFECT: expanded performances.
