I’m looking for ideas on a pallets or mass workholding or fixture plate or something, that fits on the nomad and can handle 38mm diameter rounds 1mm thick for diamond drag engraving. I’m making them one at a time now, but I want to make a production run of it.
My first experiment was with pockets milled out of aluminum plate and eccentric nuts that partly intrudes in to the pocket. Unfortunately it is proving to be extremely difficult to use that. The rounds i bought or not precision and can be out of round by as much as as 0.48mm which means I need an over sized pocket and a lot of force on the eccentric nut. I’m having the rounds spin and occasionally pop out.
Is there a better way to do this? I make about 150 a month so doing them one by one is excruciating.
