Abstract: The precision lapping and polishing device for external cylindrical surface of disk part and its taper error adjustment method. The device composes a circular baseplate, slant rails, baffles, pressure plates, copper blocks, a washer blanket; blanket plates, a set of bead shafting, a friction driving wheel, a DC motor, a mobile power supply, a LED lamp and a cover body. By adopting the working principle that the generatrix rotates around the fixed axis to form the cylindrical surface, the ultra-precision machining of the cylindrical surface of disk part is realized. The radial-continuous-automatic-micro feeding of the disk part is realized by thinning the thickness of the circular baseplate which is internally tangent to the generatrix of the circular baseplate during the process of lapping and polishing. The device has the advantages of operating simply, adjusting conveniently, low cost and is of important value for popularization and application.
