Abstract
PURPOSE:To lap concave spherical surfaces with high precision, by rotating and revolving rollers in conical roller bearing, and by enlarging the swinging angle of a lapping rod fixed on one roller. CONSTITUTION:When inner track ring 10 of a conical roller bearing is rotated by motor 15 via driving member 11, roller 8 rotates and revolves between inner and outer track rings 5 and 10. Lapping rod 9 fastened to roller 8 makes the same movement. On the other hand, a work having a concave spherical surface is fixed to work holder 2. This holder 2 produces lapping pressure due to the air pressure supplied between it and guide 3. Consequently, by selecting the central angle of the roller properly, lapping and processing are operated on the entire concave spherical surface of the work.
