Thanks for the quick reply Geoffrey.
Ok spindle it is, the router is out. My old router speed was 30000 the spindles that I was looking at has there speed range 3000 to 12000 for the 600 watt and 24000 for the VFD and spindle all my bits are single flute and V bits.
What do you mean about speed range
what speed range should I be looking for?

I just checked here Cutting Speeds - LittleMachineShop.com
and for a 6mm cutter is says about 2500 rpm for aluminium, I'm no expert on this though so just using the figures given. This implies you do need some speed control and 3000 may be a reasonable lower figure. Having looked at spindles, in some cases 24000 rpm is a special case in that it needs bearings to suite, 18000 rpm max. may be a cheaper route.

Also very important, the power of the spindle is usually quoted for max speed, so a 1.5kw 18000 rpm spindle would deliver 1.5kw at that speed only. At a lower speed it would be derated so would deliver considerably less. With this in mind and the fact you want to cut aluminium at low speed then a 1.5kw spindle would be the minimum I think.
