MULTI-CUTTER DEVICE FOR LATHES Russian patent published in 2024 - IPC B23B29/00 

FIELD: metalworking.

SUBSTANCE: invention can be used for turning the outer surfaces of axisymmetric parts. A device for turning the outer surface of an axisymmetric part contains a tool holder with roughing, semi-finishing and finishing cutters installed in the axial direction and a hydraulic amplifier for the vibration amplitude of the finishing cutter installed between the cutter holders. The amplifier housing is rigidly fixed to the tool holder, and it contains two hydraulic cylinders connected in series. The transfer of vibrations from the rough cutter to the finishing cutter is ensured with a gain greater than unity. The finishing cutter body has a built-in cutting insert for semi-finishing, which is rigidly fixed in it. The cutting plate for finishing is mounted on two cylindrical guides and is fixed relative to the cutter body by elastic elements mounted on the cylindrical guides.

EFFECT: improves the accuracy and quality of processing.
