Need info on coining
(OP)
(also posted in Machines and machining engineering)
I'm looking for information on coining. The application is a vending machine that makles coins as you watch. What I need is some information on the tonnage required for coining and if the speed is critical. I have seen coining presses in the mint on TV and they operate at high speed. Can you press a coin slowly? I want to use hydraulics with a small motor (cycle time around 30 to 45 sec.). Does anybody know of any good sources of information on the coining process either on the web or books?
TIA

In all types of coining, the press must be capable of absorbing the impact load or the coining tonnage without a breakdown of the lubricant film in the bearings - in other words, make sure it is a coining press.
