1.All BP tables are 9 inches wide and various lengths, 2. The X axis travel varies between table lengths and if it has a "Bridgeport" brand, X axis drive or other drives. I believe mills installed with the Bridgeport drive, has a lead screw and travel that is 3" shorter; table length the same. 3.All J heads (series 1) are the same casting.
The good thing about the other makes is that although usually more substantial than a Bridgeport they dont have the name Bridgeport on them so tend to be cheaper, or at least in the UK that is the case, I paid £400 for my series 1 CNC Bridgeport 3 years ago but only £200 for the Beaver NC5 last year and the Beaver is far far superior to the ...
At work we recieved a bridgeport series 1 cnc knee mill with a analim control. the analim had a mind of it's own, it would follow codes once or twice then go to the back field.

We recently bought a series ! with a non functional Anilam control. We were told that thePC cards were destroyed by a lightning hit.

Centroid using old motors 2 axis Trak We would prefer a 2 axis machine.
