Hi All

Can one of you who has got one of the spindles running ,just confirm the usable speed range you are getting .

Thanks

I get from 0 up to 24000 RPM. My VFD reads 400 when it is running at 24000 RPM. I created a chart in a spreadsheet to calculate the exact RPM for a given frequency. Usable is from about 6000 and up.

On my VFD you can set a scale factor (6) to the HZ reading so that it will read in RPM.

Maybe yours has a similar setting.

I will be finding out for myself soon as I have just ordered one of the 2.2Kw spindles with VFD so get ready for the questions on setup

Has anyone tried one of these spindles with flood coolant?

Has anyone measured the runout on these spindles? Does it come anywhere near the published specs?

Could one of these spindles be powered off of 220v clothes dryer connection?

[yngndrw]

They just need a ~220V AC supply of the correct current rating. (7-8A for the 1500Watt spindles, 10A to be sure though.) Either 50 or 60HZ will be fine.

[jalessi]

A 220-240 clothes dryer connection will provide more than enough power for the spindle VFD.

A typical electric dryer consumes over 5000 watts and requires a 30-amp outlet.

Hi All, this is how I did the water cooling
