Info on Chinese suppliers, their reliability and reputation

ok ... so can I be more specific :) I'll ask about one component at a time ...

Any recommendations on where to buy a spindle ?
What power should I consider for cutting MDF ? (and as with most people , there is that desire to cut ally ! lol )
(I'm currently using a 500w Bosch Router)
should I get the VFD with the spindle ?
Stateside, they seem to like the Hitachi controlers ?

Whatever spindle you get I would highly recommend one with an ER20 collet so you can use up to 1/2" shank cutters.
As you will be aware there is a wide choice and even wider price range so it might be easier to set your price range first then see what's available within it.
I know the 1.5kw and 2.2kw Chinese spindles are popular and come packaged with a VFD all at a very good price, myself I went for an Elte spindle and an ABB inverter
because I want it to work and keep on working. The spindle was expensive but what I'll save building the machine myself will cover it and as it's for the wife and me to use
I thought we were worth it.

Yes.

Depends how fast you want to cut it, but generally people get the 2.2kW spindle simply because it has the larger collet size.

should I get the VFD with the spindle ?

Yes. I don't know anyone whose broken one in normal use.

Whilst were on the subject of spindles ... I keep forgetting, I have a Freud 2.2kw router 1/2" collet with speed control, that I haven't used for years ! ... what are the advantages of a water cooled spindle, over using a big router ?

[Want2build1]

ok
I'm going to buy this one ... as it came up cheapest ... and they have a big feedback ... ?

Fingers crossed ...

At ebay there are for the same money or just a bit more, shipped from UK warehouse. Why don't you check?

[Want2build1]

too late :) ... paid :/

any way .. I'd like to try out the "ali" process and see if it works out ok .. the rails and bearings seem very cheap ! :)

one of my routers spun a bearing today (I have a couple of backups).. so it made the spindle issue more urgent :)

[Want2build1]

so ... to bring this thread back ...

I've bought a 2.2 wc spindle off of Ali

Linear rails/bearings next ..

anything to avoid ? or just go by price ?

Thanks

Avoid sellers without rating.

Stick to trusted sellers. /Chai or Fred/

Avoid TBR or SBR rails, buy square supported. Chinese, TBI, Hiwin,THK, Rexroth, / ordered by price/. TBI or Hiwin are the usual choice.

The 15 size are strong enough but the usual choice is 20.
