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"

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.

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!

Great product. I find it so useful on my 4060 pro. You could send longer screws to hold it down on t-slut spoiler boards. Many options on holding.

I purchased this for my CnC machine, to mill parts that I could not clamp down by traditional methods. The clamp itself is very well made, and has a good threat depth. The stand off screws were cheap and will bend if you apply to much pressure, but they are easy enough to find quality replacements at your local hardware store. My chief complaint is with the t-slot nuts that it came with, they are too large to fit the slots on my machine. A description with the size would have been nice, so I could have ordered replacement nuts when I ordered the clamp. All in all it is a very well made, and handy piece of gear...well worth the price if you need a good stable clamp.

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.)

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 fine. horrible customer service

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.
