If you work with metal you might want to consider "PLASMACAM" CNC to cut metal quickly.
That's pretty cool, haven't seen Plasmacam before.
We will typically send out for laser cutting if it is sheet metal work.
Most common things I get in metal are aluminum aircraft parts where the plane is in for a service and the part is too hard to come by off the shelf.
I had this mild steel router frame on the router machining the guides for it's linear bearing rails and rack plus drill their holes, all machined at right angle to the table.
