This is my friends families' machine shop on the southwest side of Chicago. It was started by his grandfather; not surprisingly German. They have an absurd amount of really large heavy machines that can make just about anything you can dream up - to absurd tolerances.

Large plate bender.

Painting area.


Large CNC mill.

More large CNC's.

Bridgeport endmill.

Surface grinder. It magnetizes the rotating bottom disk and uses a very large abrasive wheel to grind the face of the part flat.
