METHOD FOR COMBINED PROCESSING OF COMPLEX CHANNEL Russian patent published in 2022 - IPC B23H5/06 B23H5/12 C25F3/16 B82Y30/00 

FIELD: complex-shaped channels processing.

SUBSTANCE: invention relates to complex-shaped channel processing and can be used in instrument making and mechanical engineering when polishing small-section channels in products made of soft materials, as well as conductive coatings made in channels. The method includes anode-abrasive processing of the channel in a flowing electrolyte with electrically polarized charged abrasive composite particles while being exposed to an external magnetic field with the occurrence of vibrational vibrations in the abrasive composite particles or in the workpiece. In this case, abrasive composite particles are used, made in the form of spherical elastic granules (5), in the center of which ferromagnetic or magnetic particles (9) are placed, surrounded by a shell (8) made of plastic modified with graphene and graphene nanotubes (10), wherein graphene nanotubes are placed on the outer layer of the plastic shell.

EFFECT: elimination of caricature of the machined surface and ensuring uniform surface roughness in products made of non-magnetic soft materials.
