Embodiment
[0044] Manufacture a samarium cobalt product with an outer diameter of 42±0.01mm, a thickness of 122±0.2mm, a perpendicularity of 0.01mm, a parallelism of 0.01mm, a cylindricity of 0.01mm, radial orientation, and a performance grade of Sm2Co17-34H. The steps are:
[0045] s1) Trimming the six faces of the sintered square blank, and smoothing the six faces of the square blank.
[0046]s2) Mark the two orientation planes of the square blank as A plane and B plane 1 respectively, select two opposite planes from the four planes perpendicular to the orientation plane and mark these two planes as C plane 2 and D respectively noodle.
[0047] s3) Roughly grind C surface 2 and D surface, grind off the scale on these two surfaces, and smooth these two surfaces; draw 2~3 lines perpendicular to the orientation on C surface 2 and D surface The first identification line 5 of the surface.
[0048] s4) Carry out vertical grinding on the A surface and the B surface 1, grind off the scale o...
