VEVOR Gem Faceting Machine 180W Jade Grinding Polishing Machine 3000RPM Rock Polisher Jewel Angle Polisher with Faceted Manipulator Led Light and Water Pump Flat Grinder for Jewelry Polisher(110V)

This is easy to use. Customer support is amazing! Helped me at every step. Well worth the money, good tool.

Not terribly full-featured, although, the programmable controller may have features of which I am unaware (the instructions are obviously translated into English, and thus are difficult to understand -- not a recommended course of action for something as highly technical as a PLC). Still, the speed control is very intuitive. Also, the mast is good and solid, the faceting arm likewise, and, despite another user's complaint, my unit did come complete with a master lap, 4 dop sticks, the water pump, water supply drip valve and pipe (although I'll be replacing the hose clamps with something of better quality), and the faceting angle stop, plus a 60-grit lap. Add a water-drip tank, a drain catch bucket, and various higher grit laps, and dopping equipment of ones choice (I recommend a 45° adaptor, dopping wax, and a melt pot), and this unit is ready to cut and polish gemstones.

Missing parts. Unshielded electrical. Still looking forward to using this machine once issues are fixed

I bought this march 6th. Used it maybe once a week (April 24th) and the base is no longer spinning. The motor is spinning. I checked the tension nut that is there and it’s tight. I can’t even exchange it. Waste of time and money.

Happy with my first setup!

Awesome product. I’ve already bought 17 more for my students to use.

The machine is ok for cutting, but hard to replicate your settings. I bought the Digital display angle manipulator from Amazon for $93, and the Angle Dop 45/90 degree combo with the dop jig transfer from Amazon for $129- they have a 14 buck model that looks like it might work. I haven't received the transfer jig or angle combo yet, but the digital manipulator fits the machine and has graduations on the vertical shaft, I have high hopes. Will put lines on the base of the machine so I can return more accurately to the distance from the turntable when polishing. Cuts good with the 600 grit wheel, and I can see how it will make quality gemstone cuts, 1200 grit might be better, but it's fast. The water dripper works ok, you adjust it and forget. Nice to have the variable speed. I did the cutting on my first stone at about 12 or 13, that way the water doesn't get flung off the turntable. The plastic splash guard has a removable insert for cutting the waist at 0 degrees. You might have to get creative with spacing so your stone sits right. I took the vertical adjuster off for that. The brass bushings that help everything fit the vertical shaft are nice and tight, I used a little peanut oil to lube them (I had some cooking oil that was turning rancid, it was a nice light oil). I ordered some aluminum oxide polishing disks from a lapidary store and I'm planning on using the aluminum table that came with the machine to put them on. The cheapest good machine I have seen is about 2 thousand bucks, so for getting an idea of what is involved, this is a good machine. You have to figure everything out for yourself, the assembly pictures are ok, but the translation is hilarious! The indexer is a nice feature, and you should be able to get other indexers for different cuts, but the locking collet for the dopstick is iffy, if you take the dop stick out, good luck getting it back in exactly. There is a bag of green things that are included in the box. I have no idea what they are. Not wax, better buy some or use glue to attach your stones. Maybe the green things are practice stones?

The product does not have any rubber seals on the screws that hold the water basin to the body of the machine so if the basin backs up it will drain directly into the motor.
