Abstract: The disclosure relates to a machining station for machining platelike workpieces (1) by means of at least one tool (10, 13, 14). The machining station has a measuring device (16) for acquiring data relating to the position of bores, a drill (10, 13, 14) for generating bores in the workpiece (1), and a data processor (17) for processing data of the at least one measuring device (16) and/or for controlling the at least one drill (10, 13, 14). The data processor (17) is here suitable and set up for performing an adjustment between a desired drilling position and/or a desired bore depth and an actual position and/or actual depth as determined by the at least one measuring device (16) for a bore present in the workpiece (1), and adapting the drilling position and/or bore depth for generating bores by means of the at least one drill (10, 13, 14).

Abstract: The invention relates to a device and to a method for machining, in particular, drilling printed circuit boards (PCB) having several conductive layers (Ln). The device has a drilling spindle (2) bearing an interchangeable drilling tool (1). The drilling tool (1) has a lateral surface that has a non-conducting layer (9) at least in sections, and a core (8) that is conductive at least in sections.
