Hello guys, I hope you're all doing well.
Not so long ago (or may be yes) I recall reading someone on this list talking about an idea of using plastic pellets as closing valves for an MDF vacuum table. The basic idea was: The pellet falls into a spherical hole that has a round groove with a slight angle on its side. So when the vacuum is not applied the plastic pellet can slide thru the groove and leave the hole open (I imagine that the vacuum pump could be reversed so one can blow to clear the holes and force the pellets to the groove quicker). When there is a part over that hole and before the pump is on, the vacuum will be immediately sealed by the part, not allowing the suction to suck the pellet. Once the hole is again free, the suction will slide the pellet until the hole is sealed (useful to avoid vacuum loses on the path where the tool cuts the material). Are there any practical examples or any real life experience of this idea? That would be more than useful. Thanks as always! _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
