METHOD FOR FEEDING CUTTING FLUID TO GRINDING ZONE BY ACTION OF HYDRAULIC SHOCK Russian patent published in 2002 - IPC

FIELD: machine tool manufacture, material cutting, possibly systems for feeding cutting fluid to grinding zone. SUBSTANCE: method comprises steps of feeding technological cutting fluid through axial cavity of rotating mandrel to radial openings communicated with cavity and to grinding zone through radial ducts provided in near-end portions of grinding disc. Said portions have variable height due to acute inclination angle α of central portions having no ducts relative to plane normal to rotation axis. In description of invention relation is given for determining value of above mentioned inclination angle α in depending upon height of maximum outer diameter of grinding disc and height of its central portion without ducts. Cutting fluid is sprayed by action of impulse pressure to axial cavity, openings of mandrel and ducts of disc by means of hydraulic shock created by concentrator arranged on rod of hydraulic striker. EFFECT: enhanced strength of abrasive tool and efficiency of grinding process, reduced wear of tool, lowered temperature. 2 cl, 7 dwg
