<p>It is desired to improve a coordinate drilling machine with regard to the centering in an economically simple manner in such a way that workpieces can be clamped in a grid in a defined manner at any grid point. This is achieved by a computer allocated to the machine being designed and programmed in such a way that a grid clamping plate (3) and a spindle head (13), with regard to a tracer provided on the spindle head (13), can be moved by means of electronic handwheels (5, 6) up to the stop on a clamping means, and the computer can be taught this position as a relative zero point of the clamping means, and by the computer knowing the corresponding relative zero point after the input of the type of clamping means and the allocated reference hole of the grid clamping plate (3), and by it moving the grid clamping plate (3) relative to the spindle head (13) after the input of the coordinates of the desired centering bore with regard to the relative zero point. This coordinate drilling machine permits the centering and spot drilling of any workpiece with the shortest possible ancillary and production times. <IMAGE></p> |
