The invention relates to a grinding method for the inner and outer diameters of a step hole thin-wall steel part, which realizes the center alignment adjustment and the positioning clamping of the precise step hole thin-wall steel part by adopting an innovatively designed clamp and solves the problem of scrapping of parts caused by deformation caused by the clamping of the clamp during the grinding processing of the precise step hole thin-wall steel part in the production of products. The invention is suitable for processing various precise step hole thin-wall steel parts, has high positioning precision, simple operation and convenient workpiece loading and unloading, axial clamping force is firmly adsorbed on a working surface by a permanent magnet, radial clamping force can be uniformly acted on a clamping workpiece, and the clamping force can be adjusted in a certain range according to different conditions. The processing range is wide, and the applicability is strong. |
