PLANAR SURFACES DIAMOND-ABRASIVE WORKING METHOD WITH USE OF PULSE LOADING Russian patent published in 2007 - IPC B24B7/00 B24B1/00 B24D7/06 

FIELD: machine engineering, possibly grinding and polishing flat surfaces of parts of hard-to-grind metals and alloys having trend to occurring burnings and micro-cracking.

SUBSTANCE: method comprises steps of imparting to intermittent end tool with diamond-abrasive segments rotation and cross feed for each doubled stroke of table with blank; imparting to diamond-abrasive segments pulse reciprocation radial motion; using tool mounted in spindle with central lengthwise opening and having body with radial T-shaped grooves on its end. Cleats with rigidly secured to them plates for mounting diamond-abrasive segments are mounted in grooves of body with possibility of radial motion. Cleats have inner end inclined by acute angle α relative to cross plane of cleat. Tension springs are arranged in grooves of body and they are secured to outer ends of cleats and to body for shifting cleats to center of tool. Mechanism for pulse loading of diamond-abrasive segments is in the form of hydraulic pulse generator whose striker is mounted with possibility of percussion action upon wave-guide. In the result sad segments perform axial oscillation non-related with revolution number of tool.

EFFECT: enhanced efficiency and quality of working, intensified grinding process, enlarged manufacturing possibilities of grinding process.
