At the moment we are laser cutting plates and assembling them by hand, which is very tedious. There are channels at the entrance and exit of the device that couldn't be done with a CNC machine unless doing several plates, and we would then still have to assemble them by hand. So at best the CNC machine would replace our laser cutting machine, so it's not worth it.
