Abstract

The invention provides a microsphere yttrium barium copper oxygen high-temperature superconductor grinding method, and belongs to the technical field of micro-machining. A grinding machine is adoptedto grind cubic yttrium barium copper oxygen superconductors to machine out sphere yttrium barium copper oxygen superconductors. Micro yttrium barium copper oxygen samples are fixed in a cylindrical fixture; and the fixture is fixed on a horizontal worktable. An included angle between the worktable and a grinding wheel main shaft is adjusted within 5-10%. The rotating speed of the grinding wheel main shaft is set within 2500-3500 r / min. The feeding quantity of the worktable in the horizontal direction is set within 0.2-0.5 mm / min. Then, the rotating speed of the worktable is adjusted within 200-300 t / min. The samples rotationally move along an X axle. The radius of the samples is about 0.9 mm after machining. The invention realizes a new microsphere yttrium barium copper oxygen superconductor machining method.
