Chinese CNC machine...whatchathink?

Now having never dealt with water cooled spindles, inverters etc, I'm a little confused by the seller's response to me asking him to quote me for one! (the ad is here... http://cgi.ebay.co.uk/ws/eBayISAPI.d...:X:RTQ:GB:1123 )

Me: "Could you please let me know if this machine can be supplied not only with the 300W spindle (as per your advert) but also a VFD & water cooled spndle + spindle mounting bracket too? If so, how much extra would that be (including shipping) to the UK?"

Sellers reply: "Dear friendthis machine come with water cooled spndle + spindle mounting bracket too but it does not have inverter for you.and This item is ready for using there is no need the inverter
best regards,

This wil be the bit where I get confused - a water cooled spindle but with no inverter that's ready for use?!!

Me: "I am confused at your response....

"this machine come with water cooled spndle + spindle mounting bracket too but it does not have inverter for you"

....but your listed spindle specification doesn't mention 'water cooled' spindle, here's the extract from your advert.....

"Spindle motor 300w dc motor 1000~9500PRM/Min"

So once again, does this listing include a water cooled spindle with mount or not?

All of the water cooled spindles I've seen listed for CNC machines, typically look like this one you have listed....

(also I though all the water cooled spindles *needed an inverter?)

I am familiar that most sellers of the CNC 3040t supply a 300W air cooled spindle...this is why I am confused?

Please clarify asap....many thanks.


Seller: "this listing include a water cooled spindle with mount"




So, can anyone here clarify what the gig is likely to be here - a water cooled spindle will work without an inverter?

This is the problem everyone mentioned, you are buying from someone who cannot speak English he cannot confirm what is supplied how would anyone know what you are gonna get.

In the main water cooled spindles have an inverter but that doesn't necessarily have to be the case.

I was thinking about taking of the fan in a standard router encasing it in a water cooled jacket to cool it and so cut down the noise.

Looking at the link you are gonna get an air cooled spindle of 300W and we already pointed out that that machine is too small for a water cooled spindle.

I bought one of these machines around 3 weeks ago and it seems pretty good. I looked through the youtube vids (some are here http://www.youtube.com/user/DCTTeach.../2/J1QZrtVcv5c) and the guy who uploaded it is a DT teacher in Australia and was very helpful in assisting with the set up(I didnt quite grasp motor tuning). I bought it based on his review of the machine but from a UK supplier.

So far it has made a few nice PCBs and couple of 3d reliefs in MDF and I havent had any trouble except figuring out what type of tool does what :)

CNCDIY will mark the package as a gift, a friend ordered a different size machine and paid only £13 VAT.



On another note without high jacking this thread, where do I buy sheet wood from(pine, birch, oak etc) Im not having much luck and MDF is boring ;)
