Yes, they can cut clean enough for an inlay (no sharp corners though) only as tight as the diameter of the bit you use.
As for thickness, I believe it depends on the machine, meaning the router mounted in the carriage.
1 1/4" hardwood is a lot of material to go through, you'll probably need a 3HP for that.

I work in a shop with a commercially-sized Biesse CNC, valued at just over $100,000. While the motors are certainly capable of pushing bits through hardwood that thick, there is no way that a small diamerter bit would survive doing it in one pass. That is not a problem as it is simply done in several passes. If you want fine detail, you will likely be using 1/16" bits. They will take several passes, and slow feed rates to get through hardwood that thick.

I have a Sienci long mill on order. It will be powered by a 1.25 HP Makita router. The guys that I've spoken to on the forums say that they take 6 or 7 passes to go through 3/4 material. Think about using a router that small by hand. There is no way you could push it through thick hardwood in one go. The CNC is no different. It does not add any capacity to the router and the bit. It simply automates the process.

Like they said you set it to mill 1/8" and go watch TV or do something else and come back 3 to 8 hours later depending on how big the job.

I have the CarveWright and love the thing but it is only x-y cuts only and takes a while to do since it is a small machine and one of the first CNC that were made.

Last the biggest thing about a CNC is not the machine but the software and make sure you get a company that will be around for a while to do updates to it.

As Arlin said
You need to ensure that the unit you get has software that will accommodate that process.

I agree that while cutting using multiple small passes to achieve a final cut depth you don't need high HP but it can be something to consider depending on what and how you intend to use your machine.
There are units with very small motors and as always upgrade are available, like larger motors and even water cooled motors for more demanding tasks. I would suggest, like anything else, get the most you can afford.

I found a millworking business about 30 miles away that is buying a large CNC and plans to have it up and running by December.

I had called him earlier to see if he had a 36" wide planer to flatten out my Claro Walnut burl slab.  He only has a 24" planer but he said once he has the CNC running he would be happy to use the CNC to flatten my slab.

My plans are for mid January once my Xmas framing rush is finally over.

Excited to see what his machine can do.
