I am looking at getting a new CNC sinker. I have narrowed it down to two machines. The GF AgieCharmilles Form 20 and the Mitsubishi EA8.
I can't speak for the AC machine but we have the EA-8 and can confidently say it's a very good machine.
We also have ONA here and it runs rings around them. Perhaps the AC is as good but I'd buy another EA-8 or indeed an EA-12 in a heartbeat over the AC!
Comes down to personal choice and budget in the end as I'm sure both machines are equally reliable.
Additionally for us we have a 1st rate Mitsubishi support system and at very reasonable costs too.
