Bridgeport Milling Machine
Bridgeport 12/BR w/ 1 HP 3 phase 220/440 volt motor. Step pulley J head with working quill power feed and R8 Spindle. 9 x 42 table with working gear box power feed for x axis. Power feed motor is 220v 3 phase. Bridgeport vise w soft jaws. New Fafnir motor bearings. New Timken spindle pulley hub bearings. New Nachi low gear drive shaft bearings. Original Fafnir splined gear hub bearings unshielded (perfect condition, change not needed). Recently replaced SKF Germany matched pair abec 7 lower spindle bearings with correct preload. New Fafnir upper spindle bearing. Spindle bearings are unshielded for total loss oil lube system. Spindle bore run out is. Spindle exterior is perfect. No dings, gouges or marks. New spindle pulley brake. New felt oil filter washer. New feed trip lever. New reverse trip ball lever. New felt way wipers and covers. New bull gear oiler. Excellent quill, no gouges, scoring or wear marks. Just a few small minor dings. Smooth easy quill travel. Ram and turret have smooth easy travel. Now for the bad, and its totally subjective. Table has an average amount of drill and mill marks on its surface. Some filled with epoxy. Its not pristine but I have seen much worse. There are also some tapped holes for hold down studs. X axis movement is smooth. There is wear in the x lead screw with a backlash of. 025 in the center and. 010 at the ends of table travel. The y axis is also smooth however there is some wear in the saddle and knee ways at midpoint of travel but its not horrible and doesn’t make the machine unusable for moderate precision work and can be controlled by adjusting the saddle lock while milling. Y screw backlash is. 003 at the ends and. 018 in the center. If you are looking for a super precise machine over the entire X Y table travel, or want to make parts for NASA, this one is not for you. You should be looking at machines 5K and up. This machine is priced accordingly to its accuracy, usability, and level of restoration. I have tried to give an honest assessment as to not waste your time and ask you not to waste mine with low-ball offers. Once it leaves my shop, you own it. I can load machine onto your truck or trailer with my forklift at no charge. Thanks for looking and good luck. The item “Bridgeport Milling Machine” is in sale since Tuesday, January 29, 2019.
