Found this Spindle...please comment

Ok

as I was looking for a suitable spindle I stumbled upon this offer.
Itīs a water cooled Spindle with a matching Inverter at an incredible price!
I know, itīs chinese, but otherwise what is not made in china nowadays?
Look at this item and tell me your opinion.
To me it seems a pretty interesting offer for a Spindle of this kind.

Hmmm,
They state that they are using upgraded imported German bearings for three times the bearing life over similar spindles. I wonder...

Well, after several months of using a water cooled spindle, I would do it again. I use mine mostly to route 3/4" pine into furniture parts. It is much quieter than the Porter Cable router it replaced, and can cut the pine in a single pass if I choose. It runs at a comfortable temperature, and the speed control works reliably.
I can't say much about bearings, as I've had no problems to this point, even though I've banged them pretty hard with some stupid CNC mistakes I've made. It all seems to be working fine.

If I had a complaint, it would be that the VFD instructions were a bit vague, and that the fittings on the spindle for water tubing were just too small. If I had it to do over, I think I'd still go water cooled, but maybe with more power. This is somewhat more powerful than the Porter Cable, but I can still get it to stall if I push too hard with agressive cuts or 'accidents'.

Overall, the purchase and ensuing install project was worth it.

Hope this helps.

If my calculations are right the 3 hp pc @ 15 amps is 1.8 kw? Is your spindle 2.2 kw?

Yep. The Porter Cable is the big one at 3.25 hp, at 15 amps. The spindle is 2.2 kw.

But in practice the PC bogs down much faster than the Spindle does. I think the VFD may be a better speed control than Porter Cable has. I remember trying to cut pine in one pass with the Porter Cable. You could do it, but it really bogged down, and I wouldn't normally work the tool that hard intentionally. Also, when it bogs, the cutter speed slows, and results in hot bits and poor cut quality.

The spindle seems to hold bit speed much better. And if it bogs down too much the VFD will shut it off for overcurrent. Not long ago I had a piece of pine get stuck in my dust collector, causing my steppers to lose position. The steppers continued moving the spindle, pushing it thru full depth pine with some knots. When the spindle hit the denser knots it stopped spinning and displayed an error message. I heard the noise, and was there to press the Estop. But the spindle was OK. The bearings were fine, and the bit didn't break this time. The Porter Cable would have just continued bogging down until the magic smoke escaped.

So far so good. I used it all day today again, and it ran fine cutting pine at 160 ipm in two passes.

Hi Gerald,

The Info I provided is reffering to the chinese Spindle and VFD which I am going to use. It seems the same Spindle like Waynec uses but the VFD is different.
Waynec is using a VFD from Andeli.

Greetings

What is the name & model number of your VFD? (I don't see it at the front of the manual.

In a few month's time we will see all these funny names to threads and nobody will know what is inside of them - so everybody just starts another new thread . . . .

I wish that we could give a much clearer list of threads regarding these "Chinese" spindles (even they must have better names?).

I bought same spindle and VFD. It is 2.2KW 220V. I received some information from the seller no how to program the VFD.

I just tell you how to set up vfd as following
Firstly, adjust the PD013 to 8
Secondly, adjust the PD005 to 400
Thirdly, adjust the PD004 to 400
Finally, adjust the PD003 to 400
Note: you should set PD013, PD005 ,PD004,PD003 in order. It mean you should fistly set PD013, then PD005, then PD004, finally set PD003.
Note: after you set the all above, then please recheck the PD005, PD004, PD003 value is 400 or not to confimed that you already set it.
The reason we let you recheck is that if you do not set it at 400, then when you run the spindle motor, the spindle motor will be over-current, then the spindle will very hot and then within 5 minite, it will broken.
Regards Aoran
4. Note, please use the clean water to cool the spindle, and also do not let the dust to dirt the water. If the water not clean, it will lead the spindle to jam.

wary

The Chinese spindles look good.I am a bit wary of a company that does not know their spefications.From their spec chart:
Voltage 220
Amps 8
Power 2.2Kw
From what I know Watts=AmpsXVolts which in this case is 220X8=1760Watts.
In HP 2200Watts is 2200/746=2.94HP
1760Watts is 1760/746=2.35HP
I don't know where Porter Cable gets their specs from neither at 3.25HP.
15Amps at 115Volts would be 1725Watts and be 2.31HP.
Close enough and I would rather have the spindle with less noise.
Another thing they state on E-bay is you pay no duty and taxes as they send it as a gift.As far as I know this is against international law.Be carefull.

Larry, a spindle is a 3-phase motor. A factor of sqrt3, amongst others, comes into play. There are 3 currents, carried in 3 circuits instead of just one.

Porter Cable, and other sellers in the US market, use a "peak" power similar to that used for car audio and ghetto-blasters. For "usable" power (RMS) multiply by 0.7 for a rough indication.

There is no international law in this regard. It depends on the laws of the sending and the receiving countries. They break no laws by sending it out of their country. The onus is on the receiver to check if he is breaking laws in his country. In my country, I am allowed to receive gifts sent to me personally (not to my business name/address) up to a total value limit per year. I suspect that most countries have a similar import control system.

Claudiu, maybe I can be of help to you. What specific specs are you looking for in your spindle? Have you checked out HSD spindles? We have a few spindles that would probable fit your needs. What is your email?
