MANDREL ASSEMBLY Russian patent published in 2016 - IPC B24B39/02

Abstract RU 2594771 C1

FIELD: metal processing.

SUBSTANCE: invention relates to tools for finish machining of bores. Mandrel comprises base, gaging tooth and hardening tooth, configured to supply lubricant into processing zone. In front part of base there are nozzles to feed modifying compositions. In hardening tooth there are grooves, which provides creation of a continuous oil film in processing zone. Feeding of modifying compositions and lubricant is carried out via two independent channels.

EFFECT: result is saturation of surface of machined hole with modifying compositions and reduced friction in machining mandrel.
