A printed circuit board drilling machine is described. This concept reduces inefficiencies associated with machines which employ multiple drill spindles mounted on fixed centers. The drill machine shown in the figure employs multiple drill spindles per drill station with one or more spindles mounted on individually controlled slides. This configuration allows the drilling of more than one hole per drill station at each machine cycle regardless of the product grid system required.
