The deviation between the minimum limit cone and the basic cone in the axial direction is the axial deviation (the outer cone code is esz, the inner cone code is ES_z), and the deviation between the maximum limit cone and the basic cone in the axial direction is the axial downward deviation (outer cone code) For elz, the inner cone code is
