A two axis cnc machine with a manual quill can generate
a three axis program, if you have time and patience
Just use the single block mode, and you control the Z depth.

Old school, real old

In the early 2000s I equipped my University of Washington (UW) Mechanical Engineering shops with three Southwestern Industries TRAK 2-axis CNC milling machines.

The mills were Taiwan Bridgeport clones, actually more rigid than traditional Bridgeport mills.
(I have a similar one [manual] for my home shop.)
With manual Z axis control, the the X-Y axis CNC TRAK mills were the perfect learning machines for my students.
They annually machined nationally winning race cars in my Shops.

I really wish I could have acquired a TRAK mill for my home shop. Above my budget, though.
I used these UW machines to mill the Stephenson valve links for my Allen Ten Wheeler.
Such a simple operation for these mills! I miss access to them.
