Up for sale is a complete Bridgeport 6F-A version power feed for the table x axis. It is the first version having a seperate box that mounts to the column and houses the pc board. It is the upgraded newer style Seco electronics pc board. This unit was completely taken apart, cleaned and inspected for wear. All the major components were found to be in excellent condition and just a few minor parts were replaced to bring it back to like new condition. Cleaned armature, field windings, and motor end bells of carbon dust and oil residue. Installed new motor bearings, brushes, brush caps and brush seals. Replaced motor wire harness. Tested armature on a growler and verified no shorts, opens and ground faults. Checked commutator for wear and concentricity with dial gauge and trued up the commutator on a lathe with a Jacobs armature chuck. Cutting a commutator on centers will make it true to the center, but I have found that most centers are not true to the bearing and can be off as much as a thou. Cutting with a Jacobs Armature truck ensures the bearing surface is true with the commutator surface. Replaced clutch arm bushing. Install new directional microswitches. Install new oil seal. Inspected main spiroid drive gear for wear and found none. Install new cover gasket, switch boots, and potentiometer knob. Replace safety handle spring, drive pin, washers, bushing & locknut. They are usually dirty on the outside and almost always have sludge in the gear train with unreadable oil sight gauges. How soon before it needs service or repair? Theyr’e between 40 to 60 years old. Full disclosure, no hidden defects, no disappointments.

This thing glides like a champ. I cant find another one in all of the internet.

This listing is for an “on-site” or “at your shop” Bridgeport milling machine service. Pricing is for Midwest region. We can go to any region however the price increases a bit. The things that can cause the price to fluctuate a bit is how far out you are from St. Louis Missouri, where we are located. Also, the condition of your machine, sometimes allows for options on site that cause the price to be a little higher. Typically though it’s your choice to replace these things while we are doing the service. This basic service includes a complete upper housing rebuild, the lower spindle housing gets tuned up and spindle bearings replaced, the transmission housing gets cleaned out and repacked with grease. Things that are an added cost in the head are the splined and spindle gear hubs And the bull gears. Also if your motor shaft is all banged up, sometimes a new motor is necessary, which would be an extra cost. The base of the machine gets completely disassembled, cleaned out and reassembled with new wipers, new leads, screw, bearings, and new nuts. The oil system gets checked and limiters get replaced if they’re clogged also a new reservoir on your oiler is included because they get brittle and have a tendency to crack overtime. Things that would be an additional charge are lead screws, the oiler pump itself, Power feed and read out. Obviously, there are quite a few things they could addressed as we proceeded through the machine that are not listed in the description. Get in touch via the messaging option for further details.
