VEVOR Power Feed For Turret Milling Machine Variable Speed X Axis Torque 135LBS

Other than the plastic drive gear, these units perform as well as the high dollar SERVO brand units. The plastic drive gears are the same as the other brands, so we stock them as a routine maintenance item.

I have a Taiwan Bridgeport clone from the mid 1980's that was missing the X-axis powerfeed. The VEVOR AI-310S powerfeed is a really nice upgrade from the manual turning and provides a much better finish to my parts.

I figured I'd need to make some changes during install and was not disappointed. Had to make a stepped key to drive the bronze gear and a short 4mm key for the handle . Unit works pretty well but does not stop on the limit switches like a Servo feed does

Works great.

This power feed was used on a grizzly 10x50 mill that is no longer made and it worked fine. It was easy to adapt.

I've used a few of these style power feeds over the years, including the old school American brands and I can say they all are pretty similar in function with variations in quality. I bought a couple of the ALSGS branded ones fairly recently and I had a failure almost instantly on one of them (stripped plastic gear inside it). The other gives me fits and starts because it was assembled poorly and I had to dismantle and repair it. This Vevor one worked smooth right out of the box. My only complaint is that the included plastic nut to hold the dial in place is literal trash (it was too large for the threads and stripped instantly), and the old dial nut from my machine would not fit without massaging even though it is a metric thread of presumably the correct size. As others have said, some work may need to be done to the woodruff key and sizing of the bore to make this gear fit. Once set up it's worked flawlessly though.

These have plenty of power for any the X, Y or Z axis on a Bridgeport milling machine. I've even adapted these units to move the table and head vertically on my Rockwell EFI drill press. I can't see any reason to spend two to five times as much for competitive brands...though I have indeed done that and can verify they all work just about exactly alike. And the directions for this unit are just as bad as the directions for the $500 uniits.

Fits the grizzly g3102 mill but IS NOT bolt on and go. First get a 3mm square keyway before you start. Next the directions are useless so roll em up and smoke em because that's all they're good for. You do not use the black bracket. Instead you drill and tap 4 holes in the table endcap. Next you need to machine a 20mm x .375 collar to go behind the supplied bearing race so its centered in the bearing. Next get marking compound like you use to set up ring and pinions to set the brass gear backlash. THIS STEP IS IMPORTANT. IMPROPER BACKLASH WILL RESULT IS POOPY PERFORMANCE AND PROBABLY GEAR DAMAGE. Swap the supplied shims around till you get a good pattern. Next you have to machine .250 off the end of the hand wheel end of the brass gear so the factory hand wheel woodruff key fits in its factory keyway and the hand wheel gets installed back in its factory position. Mount up the stop switch to the 2 factory holes under the cross slide, adjust the stops and you're in business. Hope this helps someone out there with the same mill as me that is wanting a power feed especially since grizzly discontinued this mill and factory power feed option.

Purchased the AI-310S to replace a failed 150 in-lb torque power feed. The added torque is amazing. The installation in this situation was simple as the mounting footprint was identical to the original. The price is the bargain of the year. I was so impressed with the unit that I have order a second unit to replace the Z axis drive and am considering one for the Y axis feed.

Installation was easy and straight forward. Bushing keyway was too small so I made a key to fit. Was really not a problem. I’ve been using it 4 days now and running it hard all day long. It’s been great so far.
