This machine is likely to have a very low machining speed due to weak motors and other motion components. You are unlikely to be able to out-compete a professional machine shop making small parts. So while this is nice for hobbyists, it is unlikely to pay for itself in a professional situation. If you want a machine to pay for itself and be more generally useful, you would be better off spending the money on a Chinese manual milling machine.

However: consider the time taken to hunt around for a machine shop; the latency (when the machine shop can actually schedule you in); things like "business hours", etc. and suddenly this machine may become competitive with suitable automation.

I had been through exactly that a number of times before starting a business where you can order custom parts online 24/7.
