12. Cone gauge Cone angle tolerance band distribution of several types? A: conical gauge cone angle tolerance zone distribution shown in Table 3, there are 5 types. 13 conical gauge diameter of the cone diameter tolerance zone is distributed? A: conical gauge diameter of the cone diameter tolerance band is symmetrical distribution, as shown in Figure 1. 14. With the work of measuring the cone diameter of the workpiece, the work surface in the gauge how to make the axial displacement of the marking line? A: The work of the cone diameter test workpiece, the gauge surface of the displacement line Z is based on the axial displacement indicator Workpiece cone diameter tolerance according to its taper to calculate the allowable axial displacement (ie
