I make a lot of 6061 parts on my Pro4848. I have divided my machine so that a section in the front has a removable spoil board for cutting metal. I mount my vices directly to the frame and the underside has a tray to catch coolant and chips. Surface finish is an issue and I need to take pretty shallow depth of cuts, but it works. 3D profiling is fine, Recently I have done some large thread milled features. It's the older model with the V-con so the new model is supposedly more rigid. I have a separate thread trying to get examples of the difference between the two models for this application.
