METHOD OF SEALING COOLANT-LUBRICANT FEED ASSEMBLY IN DRILLING DEEP HOLES Russian patent published in 2011 - IPC B23Q11/10 B23B35/00 

Abstract RU 2432245 C1

FIELD: process engineering.

SUBSTANCE: invention is intended for cooling and lubing in drilling or boring deep holes. Annular groove is made on face surface of machined billet to mate with annular ledge of lubricant-coolant feed assembly that has body wherein jig bush is fitted. In making annular groove, tool is centered on guide surface of jig bush. Then, annular ledge of lubricant-coolant feed assembly face surface is pressed against face surface of machined billet.

EFFECT: higher accuracy of machining deep holes.
