GRINDING DEVICE Russian patent published in 2003 - IPC

FIELD: mechanical engineering; metal working. SUBSTANCE: invention can be used at two-side grinding of particularly thin walled blanks. Delivery of lubricating-and- cooling liquid is provided through bushing and axial holes in left0hand and right-hand spindles of grinding wheels. Two chambers with uniformly spaced inclined nozzle orifices are provided in device, said chambers being mechanically coupled with spindles of grinding wheels. Semi-closed zones are found on end face surfaces of grinding wheels. Axes of outlet nozzle orifices in chambers are radially aligned with axes of semi-closed zones with possibility of delivery of lubricating- and-cooling liquid into chambers and spaces of semi-closed zones. Lubricating-and-cooling liquid penetrating under high pressure into zone of wheel-to-blank contact decreases effectively calorific intensity at two-side grinding. EFFECT: increased capacity and improved quality of machining. 2 dwg
