It's some sort of press with a heavy wheel that spins back and forth
presses on the work using a heavy screw.
No audio needed, just watch about 10 seconds
What's the history of these, any is it something uncommon in the US?
**** thats old school! 1800s technology. Has to be a bitch to set
travel as well.
They were very common at one time...but they are tough to setup,
to stop, and as a result..incredibly unsafe.
Hence..they are not used in the US anymore..and havent been for
probably 100 yrs
From what little I saw the top die descends until the workpiece stops
it, which suits them to stamping identical repetitive details on
batches of variably thick hand-forged parts for wrought-iron railings
etc. I think an arbor press would be as or more useful to a machinist.
