The 2.2Kw Chinese Spindles - Info, Setup and Advice + More

This Chinese spindle thing is an expensive lottery (for me at least). If you get a spindle manufactured on Friday or during a football game you may have the AC bearings put in the same direction not face to face or even fewer as designed...

For £36 when your spending £250+ its nothing to have something tested and I know Chai does his best to get his from the better sources in China.

Didn't Solar Jean steal money off you Jonathan when you bought those drives and never got them?

No, different seller.

How do you know? If it's just based on his word, then of course he's going to say that.

When you say you make decent parts I'm taking you on your word. Of course you think you do but can you prove it? Well yes you can, I only need go ask people you've done jobs for or sold services to.

Same principle with Chai. Plenty of happy customers and very hard to find complaints.

At the end of the day its your money, spend it how you will. I've been bitten from not researching exhaustively and being too trusting. Now I'd sooner spend that bit more and go with someone who has a good rep. Take it or leave it I ain't justifying it any more than that!

Can't comment on the 2.2Kw water cooled spindles as although i have a few I have never looked into them.

However when Ketan at ARC was looking at the air cooled range he carries he bought about 6 which we ran and also stripped to see what the differences were.

Basically 4 of the vendors were lying thru their teeth about what was actually inside them, all the lies were about what bearings were fitted.

The two remaining vendors did have genuine high grade German bearings fitted and there was virtually no difference in their products.

I see no reason why the water cooled spindles do not follow this same pattern. Personally if i was in the market for one I'd go with Chai.

BTW guys just a quick question about current pricing and sourcing for these 2.2kw Spindles and VFDs. I've been searching on ebay and now the prices are over £600!! When I looked in February they were around £250-£280. Anybody know why such ar large increase other than supply and demand?

Thanks

Ive been looking the same as you and Ive decided to go for the air cooled ones because its a gamble where ever you get them because you cannot see the bearings without breaking the warranty seal, Just like john said, chai Is great and ive bought plenty of other stuff from him in the past but i may take a gamble on this

Dunno why the price has more than doubled on ebay but that now makes the 3kw spindle setup cheaper at £400

I think i'll do the same, if i get a lemon it wont be great.

I would have thought we would all be looking for ceramic bearings anyway in these, just wondering if we should start advising to go for the cheap ones and then upgrade to ac ceramic bearings anyway? or do ceramic bearings cost to much for that?

EDIT: Best price i can see for a 7005 ceramic angular contact is around the £100 mark lol.

Ceramic is a buzz word.
Ceramic bearing only come into play at speed we can't reach.

Long short is crash a spindle with ceramic bearings in and they are toast, decent steel bearings which can easily stand 24,000 revs with the right lubrication can withstand a crash provided it's not monumental.

Drop a block of steel on a tiled floor, which one comes out best ?
