This is a picture of an older Enco tool and cutter grinder I acquired some years ago, though w/o the air bearing. There is very little available on the internet or in forums from people who have or use this machine. I'm posting this note on the possibility that members might have experience with it. It works fine for me; I'm curious how others use theirs. So far I've only used it to grind lathe bits and horizontal milling cutters.
