The standard nuts that come with the spindles require a 32mm spanner. Not sure about the other spanner.. it's about 20mm, but it does vary between spindles so don't order that without confirmation.

The standard nuts that come with the spindles require a 32mm spanner. Not sure about the other spanner.. it's about 20mm, but it does vary between spindles so don't order that without confirmation.
The one that has just been delivered here (last week) I noticed that out of the box the spindle didnt turn... I tried to force it but couldnt grip the spindle. so made a mount... so I could grip it. then managed to release the spindle using a spanner on its throat / shaft
now im concerned.. because now its all wired up... it seems to make more noise than it should... this is quite hard to explain in words.. ive previously owned three of these spindles, and none of them seemed this noisy.
do I, A return it (got it from one of these UK suppliers operating out of portsmouth on ebay), or B run it and hope it beds itself in?
is there any way of greasing them?
Matt,
This might explain it, imagine a slide hammer where the sliding weight is the spindle rotor, now imagine the package being dropped on it's end, it's possible the rotor has moved through the bearings and is now catching on the frame. Can you see evidence of shaft having moved ?. During reassembly of motors it's often found that a tap at one or both ends of the rotor shaft with a hide hammer seems to free things up nicely and removes any tight spots.
If enough force has been applied to the spindle to push the angular contact bearings out of alignment, then the bearings are seriously damaged. I'd return it as it's clearly faulty. This isn't just a generic motor, it's a spindle which uses 'super precision' bearings, for good reason. Having dismantled one of these spindles, I can't really see how it could seize without it being permanently damaged.
If returning is not possible, you may have to replace the bearings which is not too difficult, just expensive.
Hi do these spindles really get shipped from the uk or are their hidden import charges. Thanks
as far as I can tell, the majority of the ones on 'ebay uk' that boast UK shipping, are, UK shippers.
Personally I think although there are 20 different 'seller accounts' selling them, they are all in portsmouth.
Now I am returning them... I have an actual address. which resolves to a generic unbranded unit

to be fair, they deliver next day, well packaged and have always been good at sorting any problems out
maybe a touch more expensive than the UK
I used 'love-happyshopping'
Thanks for the info the prices have gone up to £1220.00 OMG
They put the price up when they are out of stock. Give it a few days and it'll come back down.
Oh ok so if I buy from say lovehappyshopping am I right in saying no duty or anything to be paid? thought this was a bit of a lie as item was really coming from china.
Hi can i ask what's the best ebay make a offer price for a 2.2kw water cooled spindle that's being accepted. Im thinking of getting a different inverter as it seems people don't rate the huanyang vfd. Thanks
Can't answer the price question but the huanyang VFD is fine and about the best of the chinese ones. The earlier versions had some issues but they seem to have sorted those so I wouldn't worry about it.Quote:

Hi Andrewuk
Jazz is right. I have one of these from a supplier on eBay who ships from a warehouse in Portsmouth. It is great. Hold onto your money until the prices come down. It is Chinese New Year so nothing will happen for a few weeks yet. Once they start shipping again from China, the prices should come down. Paid about 230 pounds for mine last year.

PS Jazz I have all the bits now so about to start my cnc build!
Cool, will keep an eye out for the build log !Quote:

Hi has anyone a recommendation for a pump to cool a 2.2kw spindle and a source for a spindle mount or dxf for one. Thanks
Hi Andrew, you can find the mounts on ebay for around £30+, in the rfq section on this forum there has been one or two offers for getting a custom mount made.
For a pump you can use one designed for fish tanks, though personally I prefer the idea of using a central heating pump.

Didn't see this a week ago Mikey. Hope things go well get in touch if needed.Quote:

Or something like this 24 V Submersible Transfer Pump Water Oil Diesel Fuel Boat Camping Car Golden New | eBay if you have 24v supply. They're supposed to fit in a 25ltr container which can be used for the reservoir.
Also available for 12v
That's way more power than a central heating pump etc the one I linked to is only 4.5w and rated for 30000 hours continuously. (ish anyway) ..CliveQuote:

Your right! I got my pluming wrong, I thought he was asking for flood coolant, do you think that would be overkill as well ?Quote:

Why not put a sketch with dimensions up here and see what happens.. ..CliveQuote:

Doesn't matter just don't try starting spindle before setting the parameters.Quote:

I need to buy the spindle and am confused now.
The spindles from Portsmouth are the 3 pin type, I don't know if that means anything.I have to say delivery was fast and it was well packaged,I paid £218.00 from lovehappyshopping.

That looks Good Andrew
I have been running my spindle on and off all day, got it connected to the garden tap and outlet into the kitchen sink,. problem is I keep getting air bubbles, I used PTFE tape but got loads of air then I noticed a leak at the tap so sorted that but I'm still getting tiny bubbles, hope the spindle isn't porous, it has had water running through it most of the day so I would of thought it would of tripped the RCD if it had a internal leak but it hasn't. any ideas. Thanks
Don't worry about it will be fine so long as water is going thru it.Quote:

You won't need much coolant I have a small pump a radiator and 12 metres of pipe work. In all it runs on just over half a litre....even after 2 hours of running the water temp is only 18c. After the install i had small bubbles for 1 hour max since then i have had no bubbles or lost fluid in 7 months. You will be fine. I bet most if not all of your bubbles are coming from the mains tap water. When you do get it all sorted out use pc cooling fluid as tap water in parts of our country can be very hard. You don't want your spindle to scale up. Maybe the water is soft where you are. Cheers Andrew
Hi Jonathan, thank you for this information which proves to be very useful to me. Can you please provide me with an example of the cable as I have tried googling it up and having no result? any help will be greatly appreciated. Many Thanks
This is the type of cable you need for the spindle http://www.csecables.com/acatalog/CY-Cable-4-Core.html 1mm or 1.5mm your choice. ..CliveQuote:
