I built my own using many parts from openbuild. Nice forums for help.

So much depends on what you are trying to do with the machine, what is your budget, what available space you have, available electric service, air, vacuum, etc.

So much to consider.

A 4’×8’ bed and spindle are not going to be inexpensive and will consume considerable space. A CNC that size should probably have an ATC as vacuum hold down which increases the original cost.

I agree with DS above you need to consider what you are trying to do, create a list of desirables, cost, pros and cons of various available CNC machines. I did that before I made my choice and it took me over a year as there are many things to considder. And, don’t forget about support as it can be worth more than you think.

My CNC have a working envelope of 24”×48”×5” with a 2.2hp spindle. With the capability of optional extensions for 48”×96”×5” but I have yet not needed that option. I am not going to provide the name of my CNC to cloud your selection.

I’m guessing that if you want that size, this is for a commercial use. Correct?

The shop where I work has a Biesse 4×8 machine, with a vacuum bed. It was just north of $150,000. There are many that are more expensive in this size. Some are less, but not as robust.

I can’t edit my post. Just disregard it. Sorry. I didn’t see that you want multiple spindles.

this is my idea of a “Multi-Spindle CNC Wood Carving Machine”.
it is not for the hobbyist – so the OP must be structuring towards a commercial application.
