METHOD FOR BORING HOLES IN PRODUCTS FROM CORROSION-RESISTANT ALUMINUM ALLOYS Russian patent published in 2023 - IPC B23B1/00 B23P23/04 B23B25/00 B23P25/00 

FIELD: metallurgy.

SUBSTANCE: invention relates to boring holes in products made of corrosive aluminum alloys. The workpiece is installed in the cam chuck, and the boring bar rod is installed in the tool holder. The implementation of the generation of ultrasonic vibrations with further transmission of ultrasonic exposure using a magnetostrictive transducer and the formation of the energy of traveling waves to the cutting zone in the double amplitude mode. The boring cutter is fixed in the boring mandrel bar. Using the axial element of the boring bar, a magnetostrictive transducer is installed, the angle of inclination of which is determined relative to the direction of the chip flow vector. The direction of the ultrasonic wave action during operation is opposite to the indicated direction of the chip flow vector. The ultrasonic head is pressed against the tide on the front surface of the boring cutter moving in the direction of feed, and generates the energy of traveling waves from the point of contact with the tide of the front surface of the boring cutter in the direction opposite to the direction of the chip flow.

EFFECT: quality of surfaces is improved as a result of boring holes in products and the wear of the cutting tool is reduced.
