Which drill/grinder to use for CNC mill?

[wodkreso]

Hi.

I'm new in CNC world and ordered my Zen Toolworks. I set it up and put einhell ($30 value) grinder on it. While cutting aluminium, after 30 minutes it just stopped turning.. I guess something is fried inside.

So, question is - which drill/grinder to use for hobby projects to cut aluminium? Is 30 minutes to work at once too much for a grinder?

I got Proxxon FBS 240/E which I'll put on today, but should I be careful and make few minutes pauses after 20 minutes of work?

What are you using, and how long do you keep your CNC running at once?

Thanks,
Kreso
