The design was done in 1936 and the knee mills went on sale in 1938. They became famous as the standard for manual milling machines, and that fame continues to this day. And Knee Mill vs Bed Mill? This diagram should help: The main difference is that with a knee mill, the table moves up and down in Z, whereas with a Bed Mill it is the spindle that moves up and down. If you’re familiar with a drill press you’ll know what a quill is.

The quill moves just the spinning part of the spindle, not the motor, up and down in Z. This is usually done with the familiar X-shaped handle on the right side of the spindle head. Knee Mills are capable of a whole bunch of things that are more trouble on a Bed Mill: On a Bed Mill, you’ll have to set the workpiece at an angle to accomplish the same. That’s going to be more trouble and potentially require more expensive fixtures. Indicate from a known spot reachable by prior travels and keep going. The biggest downside is the lower rigidity of a knee mill versus a big bed mill such as is found on a modern CNC VMC. Bridgeport Mills are not just Knee Mills, they are Turret Mills as well. Knee Mills have two methods of travel in Z: their quill and cranking the table up and down. This is problematic because both are needed. The quill has limited range, and while automating its motion in CNC is the simplest and most common, the lack of travel can be annoying. Even so, back in the days before VMC’s took over and made them dinosaurs, there were many CNC Knee Mills available from Bridgeport as well as companies like Tree. Do you still use your Bridgeport Mill? What for? They’re in all the schools. The brand has a loyal following. In general, when a machinist hears “Bridgeport Mill” they think good things. They realize these mills have their limits, but that’s not the point. They also have their uses and they have served well over the years. They can’t imagine spending time to program a CNC machine to do that sort of work. Plus, the CNC machines sitting on the main part of the Shop Floor are expensive beasts. They need to be kept busy generating barrels and barrels of chips on high paying jobs. No time to help out a machinist needing a quick hole for a simple bracket. Tapping holes by power tapping on the Bridgeport is a great example. It’s easy: A fixture with the right stops will make this easy to do for multiple parts. It will pull itself in as it threads.

In the Toolroom, we’re making fixtures and perhaps a few quick prototypes or bits of tooling. You can throw together a simple plate fixture with a bunch of Mitee Bite clamps or similar very quickly on a Bridgie. Suppose you’re setting up a brand new job shop. You want a machine to perform the tasks on the side that are too expensive to run on your CNC VMC machines. I’d buy a small CNC machine. Something like this Tormach would be perfect: Present mature machinists want to know what the heck I’m thinking. Well, it’s pretty simple, really. But this is the only category where the Bridgeport wins hands down. A Tormach 1100M fits in 6 x 5 feet. Pretty close. Tooling for these two will be similar, though with a CNC some kinds of tooling are not needed (like a rotary table).BTW, think of your Tormach CNC Mill as a Manual Mill that has Power Feeds and DRO’s on all axes. It’s a little closer to the Tormach’s price. But, there are a couple secret weapons that will put a CNC Mill like the Tormach way ahead of the Bridgeport Mill. It’s built right into the Tormach’s Path Pilot controller and makes all sorts of operations super easy. In the end, you answer a few questions from a Wizard and the machine jumps in and just does it. And boy, it’ll do things that require a lot more effort on a Bridgeport Mill. It’ll do them faster, and it’ll do them right and accurately the first time every time. This is something that’s just not possible on a manual machine like a Bridgeport Mill. All that’s needed are a few g-codes and knowing how to type them in for manual execution. Don’t worry, it’s super easy and we have a great article and cheat sheet to make it even easier. All it takes is an afternoon to get the hang of it. If you’ve never used one, you may just have to take my word for it. True story! Geez, they’re completely programmable just like your VMC with the same g-code.

Our local Tormach dealer, Santa Cruz Electronics has also regaled me with many stories that are essentially Tormach purchases for second ops. I’d say they’re pretty cost effective! Normal machining is obvious and easy. More specialized uses are also common. For example, applying glue, paint, or special coatings is easy to do. Try using your Bridgeport Mill to assist with that. Crazy cool stuff! These things are money makers for a lot of folks. It’s quite easy to do on one, and it should be obvious how helpful a CNC mill would be for such an application. For sheer flexibility given its tilting head and ability to hang parts off the side of the table, it beats a machine like a Tormach. But geez, when was the last time you really needed to do that. And how many people do you know with Bridgeports that would let you borrow some time if push came to shove? They’re very handy to have around. But they are not the undisputed challengers for their niche. Canny buyers should be looking at whether the latest crop of inexpensive small CNC Mills wouldn’t be a better bet for their needs.

VintageMachinery.org does not provide support or parts for any machinesPlease remember that safety standards haveIt is up to the individual user to useThe VintageMachinery.org. It was first manufactured in 1938, by two immigrant Swedish engineers Magnus Wahlstrom, a toolmaker, and Rudolf F. Bannow (died 1962) a pattern maker and radio ham.

By 1929 they were in business together and attempting to develop an electrically-powered hedge clipper; however, when this idea was abandoned they began work on a vertical-milling attachment designed to fasten to almost any of the hundreds of thousands of plain horizontal millers then in use. With this much more useful specification business began to pick up and, by 1938, with sales of 500 units per annum, and seeking further expansion, the partners decided to incorporated the head in a completely new design of highly-versatile milling machine that they would produce themselves - the Bridgeport. Apocryphal, no doubt (but with the ring of truth) the initial sketches were said to have been drawn by Rudy Bannow on a paper bag whilst waiting to unload patterns at a customer's works. Today it can be found at the Precision Museum in Windsor, Vermont, U.S.A. Because the Bridgeport was extremely well thought out its versatility was quickly appreciated in both toolrooms and production plants; not only did the whole upper turret pivot on the main column, but the round horizontal ram (driven by a rack and pinion on some but not all versions) could be moved forwards and backwards over a distance of 12 inches; once that setting had been achieved the whole assembly could then, if needed, be swung left and right and the head tilted over under the control of a large worm-and-wheel gear - the latter arrangement ensuring alterations could be made quickly and with great precision. The value of this latter feature can only be truly appreciated if you have ever have struggled to hold 75 lbs of cast iron in one hand - over at an angle in perfect alignment with an engraved mark - whilst simultaneously trying to tighten a miserably-small nut buried in some dark and oily recess hidden away at the back of the machine.

Probably due to difficulties with rigidity, not all models had a clevis on the vertical-head end of the ram, later types being fitted with a more robust flat surface but retaining a clevis at the other end to mount a slotting attachment. As an interesting aside some early (round-ram) machines have been found with a Type C head having a much-improved quill travel of 5 inches, rather than the usual 3.5. Continued below: A further advantage of the side-drive motor was that the quill was left clear for a draw bar to pass through and retain cutters or their holders - some millers of this type, while having the same quill-feed arrangements, employed a motor fastened to (and so blanking off) the top of the spindle housing - so forcing the employment of awkward-to-use screwed retaining rings on their noses (a further consequence often being the need to use expensive custom or at least non-standard or modified cutter holders). Details of the various milling, drilling and boring heads can be found here. On March 18th, 1954 the 20,000 th machine left the Bridgeport factory (a building newly-erected two years earlier) bound for the Pioneer Electric Research Corporation of Forest Park, Illinois. Despite one machine being produced every 45 minutes, such was the demand for machine tools in the early 1950s that a sixteen-month backlog of orders, totalling over 3,600 machines, was not an unusual position for Bridgeport to be in. Some versions were adapted for CNC control and the very first Bridgeport CNC miller owed much to the design of the Series 1. By 1963 more than 60,000 examples had been manufactured, with plants in Bridgeport Connecticut, USA, Leicester and Bridlington in England - and Singapore. It was also a widely copied machine, with dozens of companies in Taiwan - and even fourteen in Spain at one time - turning out examples of greatly varying quality and performance.

Today Bridgeport makes not just millers but turning and grinding machines as well, a sale being made to Rolls Royce in 2006 of a large and complex grinding machine on which to finish jet-engine parts. As the years went by demand for the machine changed and costs came under increasing scrutiny; under various ownerships production was shifted around the globe and when owned for a time, by Textron, the machines for the USA market had their main castings poured in India and then shipped to England where the column, knee and table were built up. In 2002 (at machine Serial Number BR-247388) Hardinge took over the rights to Bridgeport's knee-mill designs (on a 7-year arrangement) and then, in November 2004, acquired full rights to the Bridgeport name to join Hardinge-branded high-precision lathes, Kellenberger cylindrical grinding machines, Hauser jig grinders, Tschudin high-production cylindrical grinders, Tripet internal-grinding machines and Hardinge-branded collets, chucks and indexing fixtures. The continued use of the Bridgeport name seems assured with Hardinge currently having over 800,000 square feet of manufacturing capacity in its operations in England, the United States, Switzerland, Taiwan and China. An interesting article about manufacturing the Bridgeport can be found reproduced from the American Machinist Magazine for November 2000.
