CNC Spindle, MYSWEETY 500W Air Cooled 0.5kw Milling Motor and Spindle Speed Power Converter and 52mm Clamp and 13pcs ER11 Collet for DIY Engraving

I ordered this to replace a smaller 300 W spindle on my 3040 CNC router. The reason i picked this one is, it has the same diameter and fits the same holder. Some 3040’s require a little bit bigger operation to swap out the spindle for a bigger motor than this. I changed all my wiring and connected the new motor. First I thought the spindle wasn’t running, but then I noticed my speed pot was in the bottom third of its range, at about 30%. This spindle runs so quietly, I just didn’t hear it. After you turn it up past 50%, you can hear it running. I would say it’s at most 30% of the noise of the original drive. It’s running very quietly, no noticeable run out, plenty of torque. Actually it has about 66% more torque than my old 300 W spindle. I have not cut much with it yet, but I am still extremely happy. I wish I would have started with this drive. One comment I would have for people wanting to use this as a mill. We run other bigger machines as well. To me a mill is probably mostly used to machine aluminum and other metals. That requires lower rpms and more torque. That’s not what these smaller routers and spindles are designed for. These smaller machines and spindles are for routers and engravers. That requires higher rpms and normally less torque. This spindle works perfectly for that purpose, and it can perform these functions at a great speed and accuracy. As one can see in the attached pictures, I used this to route 3/4 in maple for my backlit acrylic picture holders, I run 1/2 plastic, HDPE, 1/4in acrylic, and I use it to engrave my backlit acrylic pictures. So, clearly it does all these jobs, and I think it does a great job. But you need to pick the right speeds and bits for the job. I would definitely recommend this spindle and I am very happy with my purchase.

Excellent spindle for the price. I have been using a 2 hp router on my CNC with the ensuing noise and power consumption. I would have preferred a 1 hp or approximately 750 watts air cooled spindle with a higher RPM for a competitive price, but this one seems to be a good entry unit. The noise level at full RPM is less than 1/4th of what the router made and is quite comfortable. Installation was easy, except that no wiring diagram or schematic came with the unit, so I had to go back online to see what went where. The bolts for the clamp did not come with nuts or even the metric size and thread count to accommodate using them. The holes in the clamp easily fit 1/4" bolts.I do almost all my work with hardwoods and discovered that 500W is adequate thus far. I will be doing some pocket work and will discover how accurate this is. Most of my work is with 1 to 1.5 mm bits for lettering and 10-degree engraving bit for fine detail.My complaints are minor, and I believe this is a good value, works as it is advertised and I am hoping that a brushless motor will last a good long time.Some Additional information as I have now used the spindle for some work:I like the spindle because it is much quieter than my 2 hp router that I had been using, however, I have some concerns and probably should have gone with a 1kw spindle. 1. It does not seem to be as stiff as I had expected. The cutting bit under heavy load would deflect about 1.6-2.0 mm. I had to reduce the depth of cut and feed rate to compensate. I believe that it is the length of the shaft below the motor housing which may be deflecting.

I had an old 3d printer that was 300x300x400mm format. I took this spindle motor and combined it with the cnctopbaos 3 axis grbl controller. The controller works great but it has absolutely no documentation with it so you will need to be at least intermediate level with electronics or I wouldn't recommend going this route. The controller board has a spindle motor output from 0 to 24volts and this motor controller needs a 0 to 10volt signal to control speed. I created a cheap voltage divider and then connected this signal up to the pins that are shown with the potentiometer, now the software controls all 3 axis and the speed of the motor. Be careful using this with a cheap control board, on most of them you cannot drive this motor directly, it draws too much power and could burn up the control board. If you use this motor control and find a way to get a 0 to 10 volt signal out of your controller you won't have any problem.

The media could not be loaded. Did not work. First I had to google translate the instructions because it did not come with any. When I finally got it working, It was severely underpowered. Worse than my original 75W spindle. Guess I have to take it all apart and start over.

Awesome spindle. Dead quiet and nice power for a DC unit. The mount is pretty useless unless you design around it and I ended up making my own. I haven't measured runout but just by moving it by hand it's very solid and so far has cut flawlessly for me. I've cut a bunch of 18mm birch plywood, teak panels and aluminum engraving like a dream. Next step is to cut aluminum. Packed nicely in a well thought out Styrofoam box insert. One thing I would change is to lower the price to about $110 or so and only offer a few collets (1/8, 1/4, 5/16 and maybe a 4mm). All the other sizes never be used.

Bought this to replace a bad spindle in a 3020 Pro Max. If fit perfectly and has better run out than the original.

This spindle was an alright upgrade from my 60w with my fox alien CNC. It was still lacking some power from what I was looking for. I am cutting hardwoods more than anything. If you are debating between a spindle or router, I would hands down go for the router. The power is just not reliable. I am disappointed it took me so long to realize, but it was well worth the upgrade to the router.

Good product, working good
