Re: Automate my shop with a CNC Driller machine
What a fun project.
Let's start with what is the minimum and maximum hole diameters that you are working with? If the hole diameters are in the right range, it might be possible to use router spindles as the drill heads. I'm picturing hole sizes around 3/16'' or so which means the 2600 RPM would be a bit slow for an efficient CNC drilling machine. Correct me if I'm wrong here.
Rather than 2 gantrys, it is common to install 2 or more drill heads on a single gantry and operate them together. Each head would be independently manually adjustable for lateral spacing at some multiple of the hole spacing then all work together as a unit for drilling the hole patterns.
