DEVICE FOR COMBINED GRINDING Russian patent published in 2003 - IPC

FIELD: machining; deep finish grinding of materials liable to deformation at control of heat flux directed to part. SUBSTANCE: proposed device has hub helical working member provided with abrasive layer. Axial shift of working member is effected by means of axial delivery and fixation units made in form of elastic toroidal bottle with adjustable pressure source. Said bottle is mounted on hub between ring adjoining movable end of helical working member and end face of nut screwed on hub. Such construction makes it possible to perform roughing at maximum pitch of working member and finish grinding at minimum pitch, thus increasing productivity. EFFECT: increased productivity; improved quality of grinding. 3 cl, 3 dwg
