Manufacturing processes:
1. The bottom surface is processed and the processing volume is guaranteed;
2. The benchmark of the casting blank is corrected, and the 2D and 3D surface margins are checked;
3, 2D, 3D profile roughing, non-device non-working plane machining (including safety platform surface, buffer device surface, platen plane, side reference surface);
4. Before the semi-finishing, the correction of the side reference surface ensures the accuracy;
5, semi-finished 2D, 3D profile, finishing all types of equipment working surface (including the limit block device surface and contact surface, the insert device surface and the back surface, the punch device surface, the waste cutter device surface and the reverse side , spring device surface and contact surface, various stroke constraint working surface, wedge device surface and back surface), semi-finishing all kinds of guiding surfaces, guiding holes, leaving the remaining precision machining technology reference hole and height reference surface, and Record data;
6. Check and check the processing accuracy;
7. The setting operation of the fitter;
8. Before finishing, the reference hole of the technical reference hole is corrected, and the remaining amount of the insert is viewed;
9. Finished surface 2D, 3D, side punching surface and hole position, finishing technology reference hole and height reference, finishing guide surface and guiding hole;
10. Check and check the processing accuracy.
