MACHINING OF BORES IN METAL STRUCTURES Russian patent published in 2014 - IPC B23B35/00

Abstract RU 2524469 C2

FIELD: process engineering.

SUBSTANCE: proposed method comprises heating of cutting zone to processed metal softening temperature. To up the efficiency of bore machining cutting zone is heated by generation of heat by the end of revolving tool composed of heat-resistant bush connected with core drill which allows adjustment of spacing there between.

EFFECT: higher efficiency.
