ABSTRACT:
A drilling machine operable to drill holes in desired patterns and diameters in circuit boards and similar items and the machine is provided with a base upon which a planar support is movable parallel to the base respectively in directions transverse to each other by power mechanism, an elongated support mounted above the planar support in parallelism therewith and at least one turret-like head is rotatable about the axis of and is supported by the elongated support. Power means are operable to move the elongated support and head perpendicularly toward and from the planar base and a plurality of drill heads respectively supporting bits of different diameters are connected to power means and are mounted radially upon the head in segmentally-spaced relationship to each other, power means are connected to the turret-like head and drill heads thereon and are operable to rotate the head to dispose a desired diameter of bit perpendicularly to the planar support, and computer-type control mechanism is connected to all the aforementioned power means to energize them in sequence and in a manner automatically to drill holes in a circuit board, when positioned upon the planar base, in a desired pattern and of selected diameters.
