METHOD OF MACHINING NOZZLE DIAMOND INSERT CHANNEL Russian patent published in 2013 - IPC B24C5/04 B82B1/00

Abstract RU 2472608 C1

FIELD: process engineering.

SUBSTANCE: invention relates to machining jet-forming channels in nozzle diamond insert for gas- and hydroabrasive machining. Nozzle insert channel is roughed by coarse diamond powder. Then, channel surface is finished by polishing using the mix containing nanodiamond powder, powder of iron and alloy of aluminium with copper or nickel the following ratio of components in wt %: nanodiamond powder 2.0-3.0, powder of iron 10-13.0 and alloy of aluminium with copper or nickel 0 85.0-88.0.

EFFECT: decreased labor input, higher wear resistance, higher efficiency of blasting.
