Axial deviation is an unavoidable technical problem when drilling deep holes, and its rectifica?tion is an urgent task posed before the deep-hole drilling professionals both domestic and overseas. Analyz?ing the mechanism of the axial deviation in drilling holes, the paper proposes a new theory and method to rectifying the axial deviation of holes. The key is to specify a proper rectification point and apply a station- ary force, as have been verified in drilling experiments. The proposed procedure prdvides a theoretical and practical basis for the rectification of the axial hole deviation in deep hole drilling.
