The circular sulcus super it finishes, process manner and fluctuation feature

摘要

PURPOSE: To provide a method a for superfinishing an annular groove, which can improve the processing accuracy. ;CONSTITUTION: At the initial stage of superfinishing, a grinding wheel 3 is oscillated at an angle of oscillation (±α₁) in a range of ±14°-±24° against the center line of a circular of the cross section of an annular groove 2 of a material 1 to be processed. At the end stage of the superfinishing, the grinding wheel 3 is oscillated at an angle of oscillation (±α₂) in a range of 0° to ±14° to the center line of the cross sectional circular arc of the annular groove 2.;COPYRIGHT: (C)1994,JPO&Japio
