Genmitsu 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"

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 turned out to be a very high-quality vice which sped up my production by making it easier to change out wood and be exactly aligned where I wanted to be. It holds securely and accurately very happy.

Genmitsu makes products using great quality materials. Thats not to say you won't run into any issues. That being said, Genmitsus customer support and service has been amazing. Dont hesitate to reach out to them.

I took a "T8 8mm Lead Screw 10.24 inch / 260mm Length, Right and Left Hand Bi Direction Lead Screw with 2Pcs Brass Nuts " and this Vise, I got for the fiber laser and retrofitted it to be a self-centering vise. Self-centering vises are very expensive. So for about $100, I now have a self-centering vise for my Laser! It did take some drilling with some larger sized drill bits. It took about 2 hours to drill, mill out for the brass bushings and then tap for screws to hold the brass bushings. Worked out great and definitely makes workflow faster with Lightburn's hot key to center an object.

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.

I have two of these now. I mounted then side by side on my 3030 prover max. I had to grind the sides a little, and finesse where I bolted it. However, having two in has been really great. I get good coverage across the width of the bed. Also, having two vices allows me to clamp irregular shapes more easily. In the photo, the block is milled to the height of the vise so I can use the touch probe even when the vise is full and to find the stock bottom. (This baby cnc is a beast.)

My review IS ONLY 2 STARS in REGARDS TO IT BEING SOLD TO WORK WITH A 3018. I have the v2 of the 3018, and when you put this clamp on the aluminum table, it makes the cnc unusable because it is excessively tall and eats up about 80-90% of Z-Axis so that even with a bit shoved all the way up in spindle as far as you can get it, and on a really short bit to begin with ..... you can barely clear the top of the clamp/have no working Z-axis remaining to work with and makes the clamp unusable with the 3018 v2 for sure. NOW THAT BEING SAID. Other than wishing it had a dual speed rotation or a quick slide adjustment for going from narrow to wide setups because it takes A LOT OF SPINNING to get from narrow to wide ...Other than that one thing I think the quality, the design, the concept, etc is EXCELLENT and on a bigger CNC like my Axiom AR8-Pro ... it would be a really nice clamp to throw some t-slot nuts on the bottom and use to clamp very small jobs on my 2'x4' CNC ...so the quality of the products is very nice .... but once again I will also point out, the amount of time it takes to open from a narrow width to a wide width is still so excessive .... I still would never it use it much unless I was just doing the same small job alot, or varying widths of the jobs / holding needs to a very minimum level as it takes far to long to get from the narrow to wide spread. All in all, with that one quick-adjust design change it would actually be an exceptional clamp in my opinion and probably be worth the price tag ...but as is, with the super slow adjustment going from one extent to the other ...means I won't / wouldn't use on my large CNC and more importantly, I'm also still very frustrated that it was marketed specifically towards the 3018 and it's so so close the the upper z-limit mounted to the table that you would even have to reconfigure all your movement limits/clearance move limits to a really tight level to even be able to use it at all and then, with only a couple of bits, and with a very very limiting job-range limitation on top of that.

Good quality. Works as described. Fast Shipping.

I don't think this was intended for the 3030 but its the best low profile vice I can find online. I needed to tap a few holes on my aluminum plate of the sainsmart 3030, making sure things were still square but it works very well.

Brilliant little CNC vice, nice and low profile so as not to lose too much Z height work volume. Very sturdy and well made hold my blanks perfectly. Saves me LOADS of time setting up workpieces. Only annoying bit is that only one side lines up with the spoilboard holes at a time on my Genmitsu 4040 Pro Max, so I have to use clamps on the other side, this works fine though (you would think Genmitsu would have standardised on this)

Content de cet étau, il est précis. Il ne remonte que de quelques centièmes quand on le ferme, du côté mobile. Etonnant que le serrage soit inversé, il faut tourner à gauche pour fermer les mâchoires.

Excellent quality.

Ottima morsa, materiale robusto e di qualità. La uso su CNC e mi ha risolto il problema delle micro vibrazioni. Consigliata.
