A CNC drilling and milling machine comprised of a movable drill motor platform (20) with a laser reference point finder (30) in the form of a laser (34) that is attached to the machine adjacent a spindle (22). The reference point is aligned on the workpiece (26) with an identical reference located in a CNC computer (38). A workpiece holder (20) has two opposed bars (42) attached to a T-groove base of the drilling and milling machine, with each bar having a longitudinal notch (44) for holding the edges of a workpiece (26). A plate compression support and debris collecting member (62) collects debris and provides support for the workpiece (26). The entire platform is moved to drill or mill at predetermined computer selected positions, having the initial reference point (32) located with the calibrated laser beam.
