Commercial CNC machine lifespan?

Hi Sarah, Can you tell us more about your business and how you plan to use the machines?

Hi and thanks for the question. I am designing products and need to produce small runs to test and refine the prototypes. It's more likely that we will look to licence out our designs than to make large numbers ourselves though we may produce small numbers for commercial sale if we have got the size of the market wrong Best regards Sarah

I forgot to mention that I need to machine complex 3d surfaces so for those elements of the work manual machines are out.
Best Regards Sarah
