Sliding Surface Indexes

9. Sliding Indexes Sphere Surface Index
Sphere Index allows for misalignment of part, while still providing index along its axis
Alpha Numerical Index Locations
Each sliding index has multiple index locations for different panel sizes. Each panel style is assigned a letter.
Plates can be removed and new index locations can be added

16. Part Loading
Because the intermediate form boards are under the panels, they block hole locations during drilling. They need to be moved after the first machine pass to allow machine to drill all holes.

17. Sliding/Retract Surface Index
Sphere Index can be retracted 100mm, while the slider plate remains in position.
This allows the Intermediate board to move while under a panel after first machine pass.

18. Intermediate Edge Clamp
Edge clamps on these boards also have retract feature
Clamp is now open and retracted, ready for form board to move to next location

19. Loading Method
Step 1: All index locations are set

20. Loading Method
All edge clamps are opened

21. Part Loading
Panel is brought into the cell Via crane

25. Drill Cycle

26. Part Loading
Intermediate Form Boards can be released, moved and re-indexed to allow for missed drilling

27. Parts Loading
Sphere indexes are retracted, and intermediate form boards are shifted to the new positions
