Hey Guys,
As the title states, where is the best place to buy 2.2kw water cooled spindle and VFD? there seem to be loads on eBay all stating they have higher grade bearings and original vfds. I dont want to pay extortionate prices but I also don't want to end up with some fake cheap tat that will fail in 6 months. I'd also prefer to avoid import duty if possible.
Cheers,
Charlie

Charlie. It is mainly the vfd you have to watch out for see this one https://www.ebay.co.uk/itm/2-2KW-ER2...AAAOSwyy5dHuUtQuote:

Charlie,
As the most trusted manufacturer for the cheap Chinese VFDs and spindles seems to be Huan Yang it made sense to me to go direct to them and avoid the risk of getting a counterfeit unit. They have a store on Aliexpress called Haun Yang Drive which is where I bought mine a few months ago. By buying the spindle and VFD as a set I saved some money and was confident of getting components that matched and while setting up the VFD it appeared to have most of the programming already set to the values recomended elswhere on this forum for that spindle. Delivery was prompt and I have had no problems so far. The spindle arrived with a 4-pin socket with one pin already connected to the case. You will have to buy suitable cable and wire up the supplied plug yourself. You will also need to buy whatever size ER20 collets you require other than the 6mm one provided.
The only thing I didn't like was the absence of any reply to my pre-purchase enquiry about what warranty they offered but I think you'd be lucky to find anyone giving good answers to such enquiries at these prices.
I'm in Australia. Whether there's a European supplier (you are still in Europe for the time being even with Bozo in No.10 :wink:) that can save you signifficant import duty is for you to discover.

Cheers, I already have er20 collects for my mill and I have 1.5mm 4 core CY cable for the spindle, is that big enough?[emoji848]
I've found this one on EBay, looks right...what do you think?

That looks like it is similar to the one I linked to. 1.5mm is more that enough but make sure that you securely clamp the cable to the Z axis so that there is no strain on the plug as if the plug comes loose or breaks a wire it will let the magic smoke out of the VFDQuote:

Silly me l did not notice that I was mainly looking at the vfd. Yes go for the water cooled one
You should also take a look at these spindle motors:

probably the best engineered stuff I've seen come out of China
Charlie,
When you do look at the cooling I found that using larger diameter water pipe greatly inreased the water flow from the pump I bought. The spindle fittings take 5mm id pipe but I get double the flow rate through 5m of 8mm pipe with short 5mm stubs at the spindle end than I did through 5m of 5mm pipe. PVC pipe diameters and wall thickness may vary the world over but the 5mm supplied by my local hardware store is a tight fit inside the 8mm size so gluing in the stubs was no problem using the standard glue for PVC plumbing. One of the plastic barbs supplied with the pump was just right for the larger tube, the 5mm size required an expensive extra brass barb so there's a saving to be made there as well!

Thanks, If I build another with atc I'll check those out. They look good but I'd already ordered the eBay one.Quote:
