Thank you all guys.I am a teacher and supervisor in the area of metal mechanics at a professional education school in Brazil.
These machines are in the lab I'm responsible for.
@3DDave - No, they still have. I searched the nameplates on the internet. but of these machines there were only resellers. and since they are from a few years ago, it's hard to find.
@EdStainless

Please, someone helpme identify what is the purpose os these machines.
I don't know if here are the right place to post. but I need help.
