The bearing aperture size accuracy on the crankshaft is generally required to be IT6 and the surface roughness is R_o3.2. Boring on a lathe often leads to dimensional aberrations. When the size is too small, it needs to be repaired. When the size is too large, it can only be set, and the surface roughness can not meet the requirements, which affects the product quality, production efficiency and manufacturing cost. In response to the above problems, we designed the self-guided floating reamer shown in Figure 1, and achieved good results. Lowering the table
