Oerlikon UB2

Another unusual feature is this drill press is rated for milling and boring service as well. That basically means the spindle is strong enough, and accurate enough. If you try milling with a normal drill press, the performance is poor and something usually breaks. They sold an XY table for this purpose, though I don't have one.

This press is rated for drilling steel up to 1" diameter - that's using a twist style drill bit. In cast iron, it's rated at 1-1/4". To give you a reference, the famous Bridgeport mill is rated for 5/8" in steel.
In a machine shop where i once worked, we had a horizontal drill, which looked kinda like yours, only 2 or 3 times bigger.
The name, "Oerlikon", I wonder if it is in anyway related to the AA guns US Navy ships used in ww2.
