Fin,

This is probably going to start a flame war but have seen 3 startups recently spend too much time trying to learn CNC and failing due to lack of time.

Because you are aiming for perfection on your face plates, I would suggest you get them outsourced. That way you can claim warranty should the products not be to spec. You will just need to make drawings for your parts that are descriptive and precise.

Should you still want to go and buy a machine, then you will be better served if you look at the 6040 variety with a watercooled spindle. You will need to add a coolant delivery system and probably upgrade the cables and some of the electronics.

Based on the machine you linked to, am I right in assuming you are working on a small budget? Because realistically you will need to spend upwards of £1000 to get a good machine if buying brand new. Then you will need software etc so your budget will be increased. With £2000 you will probably be able to get plenty of perfect faceplates without ever coming close to a CNC machine yourself.

Best regards

George
