I've never used a Biesse, but I've use similar Italian machine for the last 24 years.
Is this a pod and rail machine, or a flat bed? Does it come with vacuum pumps?
What ype of parts do you cut?
Typically, these machines will be much faster and smoother running than a Mach3 machine. And they'll usually be much simpler to use, but not as flexible as a Mach3 machine.
This was probably a $125,000 machine when it was new.
The biggest issue with these machines when they get older is the cost of repairing them.
If you need to get the drilling block repaired or rebuilt, that can easily cost $5000-$10,000. Some of the electronics can also get up into that range.
But, if well maintained, these machines can last a long time.
I'm currently using a 2007 Morbidelli, and it's not required any major repairs since it was new, and is still used daily in a production environment.
