First let me say the Cheap-O Chinese machines with the better spindle will be strong enough.! . . BUT. . .Unfortunately there's even more to it than what you think.?
To cut this stuff with any kind of finish you'll need flood coolant or a very Good Mist system with compressed air.
Then you have the problem of Holding down very small parts and Thin material.? It's a night mare and Even Vacuum won't help unless used with special Jigs has the parts are so small.
If you are bent on CNC then I wouldn't recommend the Chinese machines anyway has they are poor quality and can be troublesome which if your not CNC savy you won't want to deal with.
Router Style machine will Cut what you want no problem and just has good has any mill can. But Like the Mill it will need the correct cutters and tool-paths along with Flood coolant/Mist and serious thought on best way to hold down.
My honest opinion is to Seriously look at using a Punch press if volume is needed or stay with the Scroll saw thinking.!

With the scroll saw you could get sharp internal corners but will a mill/router they would only be as tight as the cutter diameter allows then you're into hand filing. (unless there's a method I don't know about)

Agree, the scroll saw sounds far better when it comes to small thin metal pieces. I have a Rexon scroll saw which is okay if I need very tight curves otherwise I'd use a bandsaw every time but you would need to make a better insert from wood around the blade with a smaller gap than the original.
For your job maybe one of these ?
