METHOD OF POLISHING SURFACE OF POLYCRYSTALLINE DIAMOND COATING OF PARTS Russian patent published in 2022 - IPC B24B1/00 B24D18/00 

FIELD: grinding; polishing.

SUBSTANCE: invention relates to methods of surface treatment of polycrystalline diamonds obtained by chemical deposition from gas phase, and can be used for production of small elements of microelectronics and other equipment operating under conditions of increased friction and wear. Proposed method comprises friction treatment of coating surface by interaction of coating surface with end of rotating disc made of transition metal. Disc is used, on the end surface of which there are diametrically located slots. Disc is pressed to the processed surface with the possibility of tight fit along the whole processed surface. Said parts oscillate along machined surface to allow self-sharpening of disc working surface.

EFFECT: possibility of polishing surface of part coating with polycrystalline diamond of small thickness and increase of processing efficiency.
