Upgrade Aluminum Bench Vise Clamp, High-Precision CNC Router Clamp for Unique Shaped Woodworking & Metalworking Milling Project, Size 9.4" x 6.6" x 1.6", Clamping Range 0-5.7"

The media could not be loaded. Works great! I like the quality, and I like that it has a hex wrench that is separate from the knob, which makes it easy to do a final tighten quickly because you can finely twist the knob with your hands and then do a quick final tighten with the hex wrench instead of having a clunky hex wrench permanently installed.The one thing that’s definitely missing from this is that sliding metal piece from the previous version of this model, where you can quickly move the metal piece sort of as a corner stop/locator so you can keep placing parts in the exact same spot. This does have a stopper/block at the very end, but it doesn’t have a sliding one. The problem with the fixed stopper that comes with this unit is that if you have a small piece to clamp, and you try to clamp it in that very left corner, well the clamping force presses against the piece unevenly, and so my tiny piece gets mounted slightly crooked. If you’re able to mount your tiny piece closer to the center of the clamp, it gets clamped very nicely. So I basically 3D printed the same stopper that came with the previous model. (You can look up the previous model to see what I mean).But overall I like the quality and am glad I bought this for my CNC!

This unit is really solidly built and works well. I did find some rust on the lead screws after a month or so, I applied some molybdenum grease and that has prevented any recurrence. This is one of those tools I thought I would use occasionally, but in reality, it gets used every week.

Product works well except that there are only set screws on the handle. If you over tighten, the set screw can strip and the handle will spin

Muy buen producto, excelente calidad, envió rápido.

I was surprised at the weight and quality of this. It does its job exactly as you would like. It works great and I use it more than I expected.

Doesn't fit my 4030v1 or 4030v2 spoil boards, must use clamps on one side. Vice adjustment is reverse threaded.

I was actually surprised at the quality. The machining is excellent. There's very little backlash in the rails. The crank is tight.It can definitely be used for precision metalwork

I own the Genmitsu PROVerXL 4030 V2 (https://www.amazon.com/dp/B0C57YC46Q). I'm a bit disappointed there is no way to directly clamp this to the t-rails on this machine. No orientation makes either the external U tangs or the recessed slots in the body line up.If the body slots had been just a millimeter or two longer, screws could have aligned with the t-slots when the handle is pointing toward the front (this makes the corner with the guide be at x=0,y=max). Or if the shafts had been just a millimeter or two shorter (with optional spacers at the ends if needed for other CNC models), that would also have achieved alignment for the external tangs, although you would need a spacer to lift things up slightly to prevent the knob from rubbing on the MDF. On this modern CNC model, the only way to secure it to the table is you have to use external clamps on the U tangs.It might be possible to create an offset T-slot nut that has just enough extra offset to fit the current slots in the bodies, using the body slots you can get a screw to almost start into the T-slot nut but it's at a slight angle so does not work as is (somebody should make this useful accessory).Another potential improvement would be a few holes in the bottom of the end bodies, so you could insert a small pin (like 3 mm) that sticks out the bottom and could be aligned with the edge of the t-track, to make it's really easy to assure the vice is square with the t-slots. I assume I will have to get out a dial indicator to align this as is.
