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.
http://www.zabawajudo.pl/zdjecia/fck/brother-nx-600-manual.xml
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.

( June 2016 ) ( Learn how and when to remove this template message ) An example of a Bridgeport clone. The head is mounted on the ram by joints that allow it to swivel in two directions. The ram can slide back and forth on the turret, which can swivel on the column.

The table sits on the knee, and it can move horizontally in the X and Y axes. The knee rides up and down the column (one form of Z-axis movement), and the head contains a quill in which the spindle can slide up and down (another form of Z-axis movement or, when the head is swiveled, an additional axis). Sharp Machinery brand mill and Anilam brand CNC controllers. It became famous in the following decades for small- and medium-sized vertical milling machines, with an iconic form of quill -equipped multiple-speed vertical milling head with a ram-on-turret mounting over a knee-and-column base. Many other companies have cloned the form. Today the Bridgeport brand still produces this configuration in both manual and computer numeric control (CNC) versions, although tool-changer-equipped machining centers are now equally prominent members of the product line. All of the heads offer variable speeds, the earlier ones via a step pulley (cone pulley) and the later ones via either continuously variable transmission (CVT) systems or variable-speed drive. Typical table sizes are 9? ? 49? (Y and X, respectively) and 10? ? 54?. Machine tapers for toolholding include Morse tapers (on early models) and the R8 taper (a widely used standard that Bridgeport created) on most models. Both Morse and R8 allow for both collets and solid holders; and a drill chuck can be held by either of the latter. Machine slides are of the dovetail type, and rotary bearings are mostly of the roller and ball types.By using this site, you agree to the Terms of Use and Privacy Policy.

(optional) Send Feedback Thank you for making Machinio better. Your feedback is greatly appreciated. Regardless of how pretty and cheap (or ugly and expensive) it is, you’re gonna need to find a good way to move it. A standard Bridgeport-style vertical knee mill will weigh about 2,000 to 3,000 lbs, depending on when it was made and what options it has. To move it, there should be a threaded hole on top of the ram that’s a hoist point. Thread in an eye bolt and start hoisting. I’ll go over some more information that you might find helpful in this post. First, a few more examples of mills and what they weigh. Then I’ll go over the proper procedures for moving them, along with a few tips that can make the job go smoothly-ish. In this post, I’m not getting into the massive horizontal boring mills or things like that. You’re better off searching high and low for that machine manual. Try not to crack the spine when you open that book for the first time. That old glue can get brittle. It usually has information on there like machine weight. A Series 2 Bridgeport is double that at 4,000 lbs (although they’re not nearly as common). They make Bridgeport-style machines and are reasonably in the ballpark in terms of weight. You can find that PDF here. Just scroll down to the bottom and you’ll see their comparison chart of their machines, which include things like machine size and weight. Take your time. It’s better to be an hour late than to no longer have the use of your right hand. Carefully read the max ratings on any lifting equipment and abide by them. Always have a spotter around. You can’t see the other side of the machine when you’re moving it, and you might not notice it tipping, either. Remove all the handles and the DRO. They break really easily if you push on them accidentally.
BAINIHU.COM/upfiles/editor/files/canon-hv20-e-manual.pdf
Here are a few methods. Most milling machines will have feet in four corners and gaps in the middle of the base to accommodate forks. Keep the forks as low as possible. If your forks are nearly touching the ground, you’re way less likely to break the machine or hurt someone. This is where you can used that hoist point (a threaded hole to accommodate an eye bolt) on top of the ram. The ram should have a mark at the balance point, so slacken off those bolts and slide it into alignment. You should also center the table in the X direction. The eye bolt should line up to where the middle of the weight of the machine is. Test it out by lifting the machine slightly and seeing if it tilts or lifts off the ground evenly. If the machine tilts forward, slide the ram further back and vice versa. It’s just way too easy to bump and break a handle when you’re maneuvering a machine out of a tight space, so it’s worth taking the 5 minutes needed to strip off the sensitive bits. Especially on a 2,000 lb machine. It’ll also give you a chance to notice anything that might need maintenance. I wrote out the steps, then added a few videos at the end that more or less show how to pull a bridgeport apart piece by piece. Plus it’s just good manners. Even if you’ve stripped a mill three times over, it’s a good backup to make sure it goes back together right. Use either an engine hoist, A-frame, or ratchet straps from a beam from the ceiling. The head will weigh a couple hundred pounds, so it’s nothing crazy to lift if you’ve got two guys. You just don’t want it falling when the last bolt is off, so secure it snugly. There should be four bolts on the front that you can remove, which will detached the spindle and the motor as one big piece. Keep in mind that most of the weight will be towards the motor. It’s a real pain in the back (literally) if you have to set them down on the ground. There should be four bolts near the base of the turret.
This one’s pretty straightforward, just make sure that the ram is retracted and it won’t tip forward. Once it’s loose, two guys can lift it off. From there, it’s just a matter of using a pallet jack or something else sturdy with wheels to move the machine around. If you’re carrying it in your pickup truck or trailer, it’ll be much more stable. Either way, remember that straps are cheaper than your machine. Use them liberally. If you’re trying to get this into your basement, however, you might want to take it apart in a few more pieces. If that’s the case, let’s continue. The table is pretty heavy, so it’s ideal if you can “catch” it with forks, a table, or something similar. Don’t rush this step. Then pull off the way covers. Pull out the gib, the feed nut bracket, and slide the saddle forward and off the dovetails. One guy can lift it, but two is better. Yank out the elevating crank and shaft (the crank that moves the knee up and down) along with the bevel gear. Make sure that it’s all loose and start lifting. This thing is stupid heavy, though, so you might want to winch it from a ceiling or something. Take your time on this one. It just makes this job so much easier. This is a really good opportunity to clean the machine thoroughly and inspect the wear and tear. Keep in mind that the clones are just that; pretty well exact clones. In fact, many of the pieces are interchangeable. Try not to break anything. My specialty is machining.

I am interested in purchasing a Bridgeport vertical knee mill, but I don't understand enough about the various models to be able to make an educated buying decision. When it does come time to look at a machine and to make the decision, I will have knowledgeable friends with me who can look the machine over. But in the mean time, I would like to be able to do the legwork myself and to track down the correct machine before involving my friends. Thus I need to understand the differences between the models. I am hoping some of you gurus will answer some questions and offer some advice. 1) I have seen references to series I and series II models. What different types of heads are there and which head do you recommend. I have been told to stay away from the variable models and to go with a model with pulley adjustments because they are more reliable. 3) I assume more horsepower is better. I know that I want a DRO and a table with power feed and power lift. Anything else you suggest. How does a CNC bridgeport compare to a CNC milling center. As a computer programmer, I can see the value of CNC so as to be able to duplicate parts. Other than an automated tool changer with the milling center, are there other huge differences between the two. Thanks, DaveTry to get one from the 1960's or newer. I can't recall when they stopped making the round ram and the M head. Just my opinion. Others may disagree.

5) The condition of these is very hard to evaluate unless you are experienced with one, and you take the one you are looking at for a test drive. ScottBelt drive and Vari-speed. Most recommend to use the step pulley model with a VFD drive. Vari-drive is just a little noisier. Don't know much about the Series II, 2 HP models. 4.Vary good location for information is here.Is it a math calc. with the hertz setting on the VFD ??? or a pre made chart. Thanks, MarkTry to get one from the 1960's or newer. Just my opinion. Others may disagree. 5) The condition of these is very hard to evaluate unless you are experienced with one, and you take the one you are looking at for a test drive. Scott That model had a Series I 2hp head mounted onto the heavy Series II base, and the head was tagged as a Series II Special. That machine weighed 4000 to 5000 lbs. My Series I mill has a Series II Special head that someone removed from the heavy Series II-Special machine and then installed it on mine. Heads are interchangable between mills Last round ram was 1955. 'V' rams started production in 1956.pg As a computer programmer, I can see the value of CNC so as to be able to duplicate parts. Other than an automated tool changer with the milling center, are there other huge differences between the two? Dave If you are doing production you want a VMC. Big difference is in speed, performance and maybe a bit of accuracy. But you can make fine, high quality parts with a nice CNC kneemill. If you want a CNC machine right off the bat I would try to find some Series 2 BOSS machine that is in good condition. They are excellent machines and as close as a knee mill comes to a VMC. They use box ways and the table never overhanges the saddle. Very solid machines. The ways are in very good condition. ScottBelt drive and Vari-speed. Don't know much about the Series II, 2 HP models. 4.Vary good location for information is here.Excellent reading on those pages. It answered a lot of my questions.
If you are doing production you want a VMC. The ways are in very good condition. Scott How does one tell if the ways are in good shape or not. Is that something that requires special tools. Thanks, DaveI will need to make an adapter to fit it to the overarm. I know that the qull travel is less. There are also some collet issues, but there are MT2 spindle heads available. As an alternate, there is the R head, which is heavier duty, but with a fixed quill. I think the movable quill would be a nice feature to have. I have leads on a few M heads in good condition, which I why I am asking.Also VFD's can normally be setup to turn the drive motor at higher than normal Hz rate. So for instance, if you set the max Hz rate in the VFD to 120, the spindle could be turned 1440 RPM's with the belt positions at 720. Running a machines motor at very low RPM's loses HP and the cooling fan on the motor is not running as much air through the motor, so prolonged use can cause overheating. Over speeding the motor can also cause problems, so I don't do it.Everyone's replies have been very helpful. I'm feeling better about being able to make an educated buying decision. I posted a couple of other questions earlier in the topic. How does one tell if the ways are in good shape or not. Is that something that requires special tools?How does one tell if the ways are in good shape or not. Thanks, Dave He had listed this Series 2 machine in the classified here several times and had no takers. Their loss, my gain. The more it disappears, the more worn the ways are. Sometimes the gibs are worn worse than the ways. Sometimes only several of the way surfaces need to be scraped to achieve good performance, etc. You could write a book on this. This would include refitting the gibs. As for the scraping vs grinding, scraping is done by hand with a manual or power scraper. Takes a lot of talent and experience.Put a little reflective tape on the spindle and point the laser. Cool,.
As usual, flat-rate shipping a rip-off. Joe Just put it on a disk mounted to an arbor with the image pasted on the arbor side, so it's up when it's in the mill. (in fact, mount one on both sides of the disk and you can use it on both the mill and the lathe). Then your flourescent lights become the strobe light.
