450 in-lb Power Feed For Milling Machine

My vertical mill is not a supported model, but I was able to adapt this 450oz/in unit to a LHS drive using a steel plate, few sprockets and a length of chain. the handle has different detents behind it, and it can be converted to a horizontal mount pretty easy. drive shaft was 8mm, so a type 25 chain fit with some relief around what used to be the bevel gear. (B09QSQZY47) Overall, once it got it in, it works as it should, easy to set speed and change direction with the left hand and add oil with the right. The steel support plate doubles as a spot to stick down a large magnetic tray with collets and mill bits. also, my light clips on in just the right spot.

As most have said, some fitting is required. For me, the key way for the lead screw woodruff key was too narrow and too short. I used a hand file to open it up. Did a little bit at a time. Everything else fit the way it should have. I have a Bridgeport J-head. It works well though. The instructions are terrible. That’s what had me drop it to 4 instead of 5 stars.

Great value but this is not a plug and play item on most milling machines. You might require a shaft extension if you have an old Bridgport power feed.

I have a Millrite MVN Milling Machine, and this power feed required a lot of machining to get to work. First when I opened the box, which was in good condition, my power feed had cosmetic damage in the form of scratches on the outside. I tested to make sure it still worked, and my mill isn't exactly new either so I decided to keep going. I couldn't use the mounting bracket this came with due to the casting of the bed ( there is this little circular lip that the dial sits in, so it is not flat). I had to machine a disk to fit in that lip and secure it to the bed. Also the drive gear fits a 5/8 shaft, but the inner diameter of the bearing in the motor assembly is much wider in diameter than 5/8, so I had to machine a bushing for the shaft so the motor assembly could sit true with the shaft. In addition the keyway for the bronze drive gear was smaller and narrower than my mill's lead screw, so I had to use a keyway cutter to widen the keyway so I could actually key it into the shaft. Lastly, in order to attach the manual handle back I needed to machine a 5/8 shaft extension to fit into the bronze drive gear and out so the handle could be reattached at the end of the whole assembly (my lead screw was too short). Some of these things were my own fault for not looking closely before, and some of them was the lack of information from the company, instructions, and listing. It works fine for what'd you expect for a cheaper power feed, but I can't say my experience was particularly pleasant or easy.

I gave this 5 stars ONLY to keep them from erasing the review. They claim that this fits a bridgeport mill. Yes it will but you have to modify it to fit. It is not a direct replacement. The key way in the drive gear is poorly machined , Shim pac was missing, and the instruction un readable. The bracket that mounts to machine had to be modified as well The ONLY WAY i got mine to work was to rob parts from other machine to get it to work. After I got it to work the motor was LOUD and runs ruff .If you contact the seller he will ask for pictures. This is a stall tactic. He uses it on other web sites too!!. I am a season machinist and I can tell you, this is JUNK . GOOD LUCK WITH COSTUMER SERVICE TOO ! Cause as soon as he gets you money the warrant ENDS.

Installed the drive on a 9x42 Jet mill, it fit perfect and installed in about 30 minutes. So far with the proper shims the thing runs smooth and quiet. Directions are sketchy but I’m more of a picture guy anyway so no problem. It was a great price, I purchased one of the opened boxes for 127.00 the box gets tossed anyway, product was perfect.

I have to give this the lowest rating. It says it is a Bridgeport replacement, but, everything in the package is metric pieces. My mill is a bridgeport clone, but I know that a Bridgeport is an American machine not metric, and my machine is SAE as well. The drive bushing is NOT 5/8" as stated. There is no mounting parts I could use. The drive servo itself is smooth and strong, but no mounting hardware was usable.

This is an expensive but very functional X axis power feed that I purchased to,replace the one on my mill. It fit up pretty well with two exceptions. First, one of the four bolt holes that attach the power feed to the table did not line up with the table. Second, the bearing bushing diameter was too small. Neither issue was a show stopper for me. I just modified the parts slightly to fit.
