The following article is focused on the implementation of a CNC machine for the manufacture of printed circuit boards (PCB's) based on open-hardware, this in order to reduce as much as possible costs in the elaboration of said plates, as well as also avoid the use of traditional methods with chemical attack that both affect the health of those who work and provide security to them. The following shows evidence, calculations, assembly and elaboration of the mechanical structure. The design and construction of an automatic lathe involves the development of a mechanical system, an electronic system and a computer system, which interact to shape the printed circuits, taking codes as a guide through the G-Code software.
