Embodiment 1
[0027] The invention is applied to the surface finish grinding of 01 parts and 22 parts of large thin-walled bearings YRT460 / P4 bearings. Part material: GCr15SiMn, nominal sizes are Φ518×Φ600×22 and Φ560×Φ461×16; grinder model: MGK7363; parts accuracy requirements: width deviation ≤50, width variation ≤6, straightness ≤5, flatness ≤5 , Roughness≤0.125, unit: μm.
[0028] Take 20 finely ground parts of the above two parts, respectively use the conventional grinding method and the method of the present invention to grind 10 parts each of 01 and 22 parts. After the grinding is completed, the instrument is tested. The test results are shown in Table 1 and Table 2. When the flatness of the parts processed by conventional grinding is improved to about 10 μm, the flatness quality cannot be further improved, and the processing accuracy of the product is unqualified, and the accuracy of the parts processed by the invention meets the design requirements.
