Customer Reviews for VEVOR Jewelry Pneumatic Engraving Machine 1400 RPM Adjustable Speed Pneumatic Hand Engraving Machines 60Hz 80W Pneumatic Graver Handpiece with Single-Head for Jewelry, Crafts and Wrought Iron

As someone new to pneumatic engraving, I was nervous about getting started, but this machine is actually pretty intuitive. The instructions could be a bit more detailed (especially for setting the PSI), but once you get it, it’s easy to use. The foot pedal makes adjusting depth super easy while you work, which I found helpful for both delicate and deep engravings on metal.

This is my 2nd engravor the first one gave us so much problems, so I’m hoping you can help me with that. We purchased it over a year ago, and haven’t had use out of it for 6 months . First thing was the foot pedal then one was finally sent after 6-8 weeks, then this plastic piece that looks like a regulator of sorts broke, so we just ordered straight from the company. So now we would like to take all these parts send them to you and see what kind. Of price I might get for a new one sent to my studio Donna Voelker Out of This World Jewelry and Gemstones

Would be nice if it had come with a air inlet hose. But works good with my medium size air compressor.

This is a great little power engraver. Like most in this category, it's air cooled internally, so you will always hear a little air going through inside when it's running. It works well and doesn't leak. I'd recommend another regulator between this and the compressor just to ensure that you don't hit this thing with more PSI than you should have (I think around 40-45 PSI is what this is expecting and what the handpieces can handle as a maximum). It comes with a filter in the mix, but you could buy a regulator/filter and bypass the one it comes with if you want to. The handpiece chucks don't quite fit 1/8" standard gravers, common here in the US from a variety of jewellery tool companies, so I had to take the chucks and drill them out to 1/8". It was easy and quick, and now I can use a variety of carbide gravers and standard HSS gravers. You slide the graver in and tighten a grub screw (set screw) to hold onto things. The handpieces leak air (only a tiny amount) but this is NORMAL. It's common in all of these, and it's just the way they're designed. Since the air has to go to the handpiece to move it, the excess has to go SOMEwhere, so it's designed to leak out the handpiece. One of my handpieces leaks a little more than the other, but not enough to really notice a difference in usability. I use an 8 gallon quiet compressor with this, and it kicks in relatively often. My compressor is designed to kick on at 90PSI and shut off at 120PSI, so it kicks on maybe every 4-5 minutes. If I had a larger compressor, it would kick on less often. If I had it set to kick on at a lower PSI, it would kick on less often. But it's a CAT compressor, and really very quiet as compressors go, so it's not a nuisance. I barely even pay attention when it kicks on and off. My shop exhaust fan is much louder. This uses 6mm OD tubing. It will TAKE 1/4" OD tubing without much in the way of issues, but you should really use 6mm if you can find it. It's cheap online from a variety of places. It does not come with enough 6mm tubing to do much more than connect the foot pedal to the main box. Connecting your compressor to the air filter and the air filter to the main box means you're going to need more tubing of your own. Controls are standard. There's a switch to switch between handpiece 1 and handpiece 2 (it comes with TWO handpieces, which is crazy for this price, but great). And then there's an 'auxillary' connection that's designed for other kinds of tools that require air. There's a 'bias' dial, which controls the starting point of the foot pedal. The bias knob should be closed when you're adjusting the machine.There's a primary air pressure knob (good for different kinds of handpieces and controlling how strong you want the pressure to be, dependent on what the handpiece will take (they're all different)). And there's a speed control knob. A FANTASTIC engraver!
