Spindle recomendation?discussion for small 3020t router

Right chaps and lasses,

I currently have a 200w spindle motor which I have been told by numerous people it is just weak as wee. So im looking to purchase a better one today, I am aware that I have to be carefull of the weight as my z axis isnt the strongest, that said I still want to try and get the best I can afford (not much as usual)

I have been looking brushless 600w spindle motor:

Is this too powerful? or do you lot think this is a good upgrade for my machine? I would like to mill soft ally mild steel at some point if poss (although I doubt it will do it)

Main duty for the machine will be mild engraving into fibreglass and soft ally.

Let me know your thoughts :-)

I'd personally say stick with what you've got until you either kill it, or reach it's limitations.
It's certainly not a powerful spindle, but it should be good enough to use while you get to grips with the rest of the machine.

I don't know the details of your machine but something like this or a water cooled one would be far better; http://www.ebay.co.uk/itm/1-5KW-AIR-COOLE-SPINDLE-MOTOR-ER16-CNC-MILL-ENGRAVING-INVERTER-DRIVE-VFD-/272043740785?hash=item3f57120e71:g:ox8AAOSwFGNWRDP u

Eddy I don't think it would fit on their machine http://go.redirectingat.com/?id=20518X781349&site=mycncuk.com&xs=1&isjs=1&url=http%3A%2F%2Fwww.ebay.co.uk%2Fitm%2F2323472905 74%3F_trksid%3Dp2057872.m2749.l2649%26ssPageName%3 DSTRK%253AMEBIDX%253AIT&xguid=c7f539f199da664b8141121af7dc960d&xuuid=ca150a3d055b313849504ddbd83ba98e&xsessid=&xcreo=0&xed=0&sref=http%3A%2F%2Fwww.mycncuk.com%2Fthreads%2F1100 0-Hello-here-is-my-new-machine%3Fp%3D91858%23post91858&pref=http%3A%2F%2Fwww.mycncuk.com%2Fsearch.php%3Fs earchid%3D2046630%26pp%3D%26page%3D3&xtz=-60

That't the trouble when people don't keep their posts in one place for the same problems

'machine' ? I almost choked on my milk stout, I suppose it's okay for PCB's and small light stuff.
In that case, I'm thinking m_c had the best answer.

Nice to see you around Eddy :thumsup:
