Question and answer of national standard "cone gauge and its verification system"
12. What are the types of conical gauge cone angle tolerance bands? A: The conical gauge cone angle tolerance band distribution has five types shown in Table 3. 13. How is the cone diameter tolerance zone of the cone gauge distributed? A: The conical diameter tolerance zone of the cone gauge is symmetrically distributed, as shown in Figure 1. 14. When using the working gauge to check the cone diameter of the workpiece, how to make the axial displacement marking line on the gauge working surface? A: When using the working gauge to check the cone diameter of the workpiece, the axial displacement marking line Z on the gauge working surface is based on The workpiece cone diameter tolerance is calculated according to its taper to allow the amount of axial displacement (ie
