DEVICE FOR SUPPLY OF SOLID LUBRICANT ONTO GRINDING STONE Russian patent published in 2010 - IPC B24B55/02 

FIELD: metallurgy.

SUBSTANCE: device consists of case with nozzle, of nozzle feeding facility including devices for conditioning compressed air and melted solid lubricant (SL), of control device and of system of pipelines. The nozzle is made with a flexible heat insulated sprayer and is located at angle to axis of rotating working surface of the grinding stone. The flexible heat insulating sprayer consists of a flexible tube for supply of melted SL; this tube is coaxially installed inside an external flexible tube made out of dielectric. Inside the latter there is placed a heating element protected with a shell made out of heat insulated moist-proof material and included into electrical circuit for heating the flexible heat insulated sprayer to temperature exceeding temperature of SL melting.

EFFECT: upgraded quality of treated surfaces of parts of machines and decreased expenditure for SL in production prime cost.
