We are about to purchase a Haas VF3, but I have heard that the MYNX 5400 is a compatible or even better machine. I want to get some feedback before I pull the trigger on the VF3. Does anyone have any positive of negative experience with these machines?
Dude, it's like night and day difference. The Mynx will take cuts on a day in and day out basis that the VF-3 won't even touch. There's no comparison, the Mynx is a real machine while the VF-3 is a toy in comparison. The MTBF on a Fanuc control is currently 33,000 hours, on the Haas it's measured in days between failure.
I've run both and if the money isn't an issue the Doosan will run rings around the VF-3.
