Need Help Identifying What Machine These Items Are For.

I recently purchased some items from an auction and in one of the boxes were some EDM parts for a Fanuc EDM. I would like to try to sell these on ebay if they are even worth messing with. However I cannot seem to figure how what these parts are actually for or how much they are worth. If someone could shed some light on this for me it would be very much appreciated. Here are the part #s
