DEVICE FOR FEEDING OF SOLID LUBRICANT ON GRINDING WHEEL Russian patent published in 2009 - IPC B24B55/02 

FIELD: mechanical engineering.

SUBSTANCE: invention relates to mechanical engineering field and can be used while processing of machine elements blanks by means of cutting with feeding of solid lubricant (SL) on grinding wheel. Device contains tank for SL and installed in its bottom part thermal element. With tank and thermal element it is connected temperature control device of SL. Inside the tank case it is located mixer. There are provided nozzle, electrically insulated from the tank and mixer and also device of compressed air preparation, control unit and pipeline system. Nozzle is connected to mixer by means of flexible tubing made of dielectric material. The latter is located inside the flexible thermal element, connected to electric circuit for heating of flexible tubing up to the temperature, exceeding SL melting temperature.

EFFECT: consequently it is provided the ability of SL feeding in restricted conditions, for instance at inner grinding and application of this invention in cases when it can be located in working area at required distance and on the required mitre.
