The Shop I work for has a 350W. We are a job shop and we don't see large production runs. It is mostly used for specific parts that really benefit from that type of machine. If tools break and the machine has to be stopped, it can be time consuming to get it up and running again, especially if it is a long program. I think ours has an OSP100 control. When we machine aluminum, and can leave it alone, it seems to be pretty efficient. I have found that the lower turret is extremely accurate, while I will see up to .oo2 deviation on diameters that are turned by the upper turret, as the machine heats up. The lower turret stays within tenths, even after weeks of sitting. But that might just be ours. I know it has been crashed pretty hard in the past. I really like Okuma controls, and I think they are pretty simple to learn. I will say that we have several Okuma turning centers and they are extremely reliable. But the Macturn seems to be quite problematic compared to those. Another thing different about this kind of machine is making sure you have a good post processor for it.
