I don't want to stray from gremac's original question too far here.
We all know what the okuma's can and can't do.
I think a huge part of a customers impression of a machine is how well they are supported after installation.
If WFL have an office nearby, with skilled staff, and customers willing to vouch for their goods and services, then that is in their favour.
If you buy machine tool XYZ because you want to make A,B and C, then sooner or later your engineer is going to want to make part D and it wont fit!
We've all had to fudge jobs, buy different tooling, or "trick" the machine one way or another to get that last mm.
If WFL rely only on their machine being bigger and better, then leave you to your own devices, then that is not a machine I would want to buy.
