A board drilling apparatus, drill bit, and method for board drilling apparatus to drill a board. The board drilling apparatus (4) is configured to drill a board comprising at least a target conductive layer (13), an insulation layer, and a hole (3) covered with conductive material through at least part of the board in thickness, to remove at least part of the conductive material, the board drilling apparatus (4) comprising a drill bit (41) and a controller (43): the drill bit (41) comprising an insulation part (412) at least in center of end of the drill bit (41) and a conductive part (411) at least on edge of the end of the drill bit (41), arranged to enable only the insulation part (412) to be in touch with the conductive material of the hole (3) when the board drilling apparatus (4) is drilling the board, and arranged to enable the conductive part to get in touch with the target conductive layer (13) once the conductive material on the way to the target conductive layer (13) has just been removed; and the controller (43) configured to stop drilling when receiving an electrical signal occurred in response to the drill bit touching the target conductive layer of the board.

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).

A coated tool, such as a rotating, cutting tool, includes a tool body and a multilayer wear protection coating system. The wear protection system coats a functional surface of the tool body that is subject to wear and includes a first undoped diamond layer and a second undoped diamond layer disposed over the first undoped diamond layer. The first undoped diamond layer is electrically conductive and exhibits grain boundary conductivity from delocalized electrons. The second undoped diamond layer is electrically insulating. The first undoped diamond layer is 4-20 microns thick and is made with diamond grains whose size ranges from 4-10 nm. The first and second diamond layers are applied by chemical vapor deposition (CVD) using a hot-wire method. The wear protection system also includes an additional undoped diamond layer that is electrically insulating and is disposed between the functional surface of the tool body and the first diamond layer.

The present invention relates to a PCB drilling method including: performing a drilling motion from an initial location, and generating a first electrical signal when coming into contact with a first conductive layer of the PCB, determining a first conductive location according to the first electrical signal, and obtaining first Z-coordinate information continuing to perform the drilling motion after drilling through the first conductive layer, and generating a second electrical signal when coming into contact with a second conductive layer, determining a second conductive location according to the second electrical signal, and obtaining second Z-coordinate information; continuing to perform the drilling motion and drilling through the PCB to obtain a through hole; and performing backdrilling in the location of the through hole according to a preset depth, and the preset depth is a medium thickness between the second conductive layer and the first conductive layer plus a compensation depth.

A cutting element (1) for a tool with an electrically conductive track (6) formed at a surface region. The cutting element (1) comprises a HPHT produced polycrystalline diamond body. The conductive track (6) comprises graphite such that the electrically conductive track (6) has an electrical resistance substantially lower than that of the surface region.

A snap adapter for a wire stripping tool has a hollow body with a tool end, a component end, and a button. The tool end is sized for insertion into the tool body and the component end is sized for receiving a component meant to strip a cable of a specified diameter. The button comprises a pin feature for attaching the received component. Inserting the component into the snap adapter forces the pin away from the snap adapter hollow body to allow for full insertion of the component into the tool body. A spring disposed between the hollow body and button pushes the pin feature upwards through the hollow body to hold the component inside the snap adapter once the component is fully inserted. Removing the component requires pushing down the button to extract the pin feature, which allows the component to be slideably removed from the tool body.
