Works excellent, good quality VFD and spindle

The bad first. The water pump didn't work but it's not why would buy this. Just plan on buying a good quality pond pump. Otherwise it has been great. I've done several 24 hour plus cuts without a hiccup. The VFD is tied into my CNC controller so the G code commands it to start, sets the speed, and to turn off once it's done. After 24 hours the spindle is warm to the touch but not hot. It has lots of power. I use a CMT 2 3/8" surfacing bit set to 8000 rpm. It handles it without an issue. I've even used a 3" half round bit. ust add ferrite beads on the power cable for the spindle.

Great price

I have been using this spindle for my CNC router for 6 months now and it has performed flawlessly. I even checked the spindle runout and detected none. I was able to set it up to work with my Linux CNC program so that I never need to touch the VFD controller. On, off and speed are controlled by the G code. I do have some minor complaints and some suggestions:If you live in the US and know your way around 220 single phase you will be fine. If not, you will absolutely need a qualified electrician. Don't even think about it if you do not know what you are doing.I also ordered a cheap set of collets from another source. YaeKo I think. If you care about accuracy dont do that. I pay about $20 each now for Amana ER20 collets and they are worth the money.Complaints:No spindle wrenches.Not enough tubing.Barely adequate documentation.Suggestions:Offer a 110v pump for US customers. It's partly for this reason that you will need to have an electrician. I happen to be one so it was easy for me. I cut the plug off the pump cord and wired it to the same switch I use for the VFD.Have an option for more water tubing and a flow indicator. Also make a recommendation on the water supply. I use a large plastic storage bin under my CNC table. I mixed in a fair amount of automotive antifreeze to prevent corrosion and to lube the pump. I don't know if I did the right thing because there are no recommendations in the doc's.Finally, provide better documentation. Especially for those wanting to control the spindle from their CNC software.Many users are DIYers that use Linux or Mach 3. It would be great to have specific instructions for these 2 programs.It baffles me why Chinese companies that make very good products like this one, offer such poorly translated documentation. For many American and European DIY'rs, this is a major deterrent. Seeing "excellent documentation" in the comments would easily return your investment on having it done better.

Works great on my onefinity journeyman. It was initially programmed to run half the maximum rpm but it’s an easy fix. Comes with a 220v pond pump so you’ll have to buy one separately if you want to run it on 110v.
