This is a CNC Router that I built based off of the book “Build Your Own CNC Machine”. The bulk of the machine is built out of Medium Density Fiberboard (MDF). The bearing rails are build out of 6061 aluminum angle. The machine is driven by 3 stepper motors using 1/2-10 Acme screws. The machine table is approximately 2’x4’ and the usable area several inches less than that.
One of the first operations after doing a few test cuts was to have it drill holes every 2 inches to provide a good way to clamp pieces to the table. You can see this operation in the second picture.
The third and fourth pictures show two of the first pieces I cut using the machine. They are cut with a half inch V-Groove router bit to about 3/8” depth.
