|Van Norman "Ram Type" milling machines are extremely versatile alternatives to the Bridgport style vertical mills that are most common in machine shops today. The unique features of the Van Norman mills are a swiveling cutterhead and a sliding ram. Combined, these features allow the mills to be used as both horizontal and vertical mills. The other outstanding feature of these mills is their great rigidity. Pound for pound, they are much more rigid than the common vertical mills, and they can take much heavier cuts.|
|The mill on the left is a Van Norman #12. This is the most common of the ram type mills. Over 5000 of them were made, mostly during World War II. At 1800 lbs, they are slightly smaller than a Bridgeport. This one is set up in vertical mode, with the ram forward and the cutterhead rotated to point down.|
|This pair of pictures shows how the Van Norman mills convert from horizontal mode to vertical mode. On the left, the mill is set up for horizontal work. The ram is moved back, and the cutterhead is rotated counterclockwise to a stop. Then the knee is raised to bring the work up to the spindle.|
|On the right, the mill is set up for vertical work. After lowering the knee to clear, the ram is cranked forward and the cutterhead rotated clockwise to the vertical stop. Converting from horizontal to vertical or back only takes a minute or two.|

You can figure out when it was made, what kind of collets it needs,

Like all web sites, this one is a work in progress. I have gathered a fair amount of information myself, and other generous individuals have supplied even more. I am always looking for more info.
