METHOD OF STEPWISE FEED OF COOLANT-LUBRICANT PROCESS FLUIDS Russian patent published in 2011 - IPC B24B55/02 

FIELD: process engineering.

SUBSTANCE: invention relates to machine building and may be used in metal grinding with using coolant-lubricant process fluids. That fluid is sprayed in machining zone hogging in and removing major allowance while molten solid lubricant is sprayed on revolving grinding wheel in sparking out. Feed of coolant-lubricant fluid and that of molten solid lubricant are separated in time into removing major allowance in dry conditions to dewater grinding wheel surface prior to sparking out.

EFFECT: lower net costs, shorter grinding cycle, higher quality of finished products.
