The machine posted in my first link, is supplied with A 300W spindle. That doesn't sound very powerful to me. My main useage would be thin plate alu. Do you think it would cope?

it looks like a reasonably chubby motor so i would have thought the torque would be quite good but i guess there is no real way of saying without knowing more about it/ how its wound

iv an outrunner that looks a similar diameter and will happily cut 0.5mm depth in alli 3000rpm 3mm single flute, the power supply is 350w but im pretty sure its drawing nowhere near that

edit: the one you show in the link will only run as low as 5000rpm not perfect but i would have thought doable with small tooling :)

Hi Mark

Apologies. I am now looking at the slightly larger machine http://www.premiersign.co.uk/proddet...rod=BC-400-300 which has the 300W motor and a variable speed of 1-9000rpm.

I'm just a little concerned how easy it would be to change the spindle to a different type if I had too at a letr date.

Thanks again for all the help

speed of 1000-9000rpm

ahhh!! that sounds better :) i would have though you would be fine with that

if you have access to a lathe making your own spindle would be a cheep option.. easy to make one to fit whatever spindle housing you already have, its not rocket science and they work quite well, there are a couple of threads on here that will talk you through the task but unless your after using larger cutters and heavy cuts im pretty sure the spindle on the BC-400-300 will be fine
