Thread: CNC Spindles on Ebay

Rod,
Any recommended suppliers of VFD's to suit these spindles?

Hi Geoff,
Mumbo jumbo to me once you get into the electrics.

Best I do it put them together after asknig questions and they work but I do not understand fully what is happening. The VFD converts single phase to three phase and becomes the speed controller. 800RPM to 24,000RPM so they are ideal for cutting all materials.

If you have a look at spindles on the Kelling site you can get a bit more of an idea and he has VFD's on there as well.

Ask the ebay seller and he should be able to supply or point you in the right direction.

To give you an idea of price I paid $140US plus shipping last Frdiay for a 1.5kw VFD but different seller. Collets are under $50 and it gives you a good range of shank sizes to select from.

If you search for the video posted by Greolt you can see one of these in action on his machine.

There's something to be said for wet weekends, you get to spend more time at the computer for research

MS-Motor have air and water cooled spindles and can supply VFD's as well. I'll ask them for prices and post the results here.

I would have thought a high power spindle router on full speed would easily heat up and get damaged too easily on air?

I've been looking at the spindles for some time trying to see if its worth it over a quality die grinder, now that the price is down there it might be worth it.



I wanted to know whats the difference between the E11 and E16 collets? I tried searching on google but didnt get any results as to what it is. I gather its the size of the collet but is E11 1/4" and E16 1/2"???





BTW Rod that supplier of yours is GOLD. Asked him about some slides and he can get the best prices out of everyone I have asked.

The worst of this is I just brought a 800 watt spindle for a another machine on Friday and paid more for the spindle and shipping.

For wood workers there is little difference between the ER11 and ER16 collets. The diference is a ER11 collet holds up to 7mm and a ER16 collet holds up to 10mm. As there are very few 3/8 shank router bits you are limited to 1/4 shank for both collets. If you are using mill bits then the ER16 lets you use larger sizes over the ER11.

Geoff is it a magnificent day in Perth with the sun shining. I have moved my bench outside and changed to a short sleeved shirt. Off to do some more work and soak up a bit of sun.

They look to be the same build as my spindle and the rice look good as well as them if they can supply a VFD as well they should be able to source them.

Otherwise Greolt has a company in the US that will supply to Australia I just cant find the email ..

Here it is,

For just a little bit more money I decided on an Hitachi drive rather than a no name Chinese one. Something you need to decide for yourself.

EDIT: Looking at that ebay add that Rod posted, is that cooled by compressed air? Looks like it. Can see no fan for cooling.

That would be no good for me. Getting rid of noise is one of the reasons for getting a proper spindle for me. Running a compressor does not fit the bill there.

I think you are right about the compressed air. It would be useless for me for the same reason - noise.

Hello Rodm

You might be right about the compressed air but it is also used to provide a positive
pressure differential within the spindle, this is to help keep the dust out, or it is at least what the docs say on mine, also the flow rate is to low to provide much cooling.

Has anyone in Australia tried the air cooled spindles?

My workshop is plonk in the middle of 80 acres, so noise is not a major problem ... except for the cows maybe! Two of my workshop jobs are to run compressed air around the workshop with the compressor outside the main workshop (still under cover) and to also move my dust extractor to the same spot and duct it around to the various machines including the forthcoming 'Alpha Zoot'.

I have not previously considered a spindle because of the cost and did not like the idea of pumping water around, but an air cooled spindle could tempt me down the track a bit.

Cheers,

Alan

Thanks Ed - It makes sense.

Hi Alan,
It is a much for the operator as it is to avoid complaint. Running a router continuosly for a couple of hours does get a bit tiresome.

Did you get the prices yet, I have asked for the 800 spindle and a VFD and just waiting for a price now. You have to be really careful when dealing with them, ask twice and then verify that is what you will be buying

Sorry, that was one of many jobs that slipped through the cracks.

Hi Geoff,

Would have been nice to compare them, not to worry
