The invention relates to a method and an arrangement for introducing boreholes into a surface of a workpiece (W) mounted in a stationary manner using a boring tool which is attached to the end face of an articulated-arm robot (KR) and which can be spatially positioned by said robot. The method has the following method steps: - positioning the articulated-arm robot-guided boring tool at a spatial position which lies opposite a specified machining location on the workpiece surface at a specified distance therefrom, - producing a rigid mechanical connection which supports the end face of the articulated-arm robot (KR) on the workpiece and which can be released from the workpiece surface, and - machining the surface by moving the boring tool towards the machining location and subsequently engaging the boring tool with the workpiece (W) at the machining location on the workpiece surface while the end face of the articulated-arm robot (KR) is connected to the workpiece. The invention is characterized by the combination of the following method steps: the boring tool is moved towards the workpiece (W) by means of an NC advancing unit attached to the end face of the articulated-arm robot (KR), the boring process is monitored on the basis of information obtained using a sensor system which detects the position of the boring tool relative to the workpiece surface and which is attached to the end face of the articulated-arm robot (KR), and the boring process is terminated upon reaching a specified boring depth.

Three systems for the destruction of the data storage portion of electronic media storage devices such as hard disk drives, solid state drives and hybrid hard drives. One system utilizes a mill cutter with which the hard drive has relative motion in the direction of the axis of the mill cutter to destroy the data storage portion. A second system utilizes a laser to physically destroy the data storage portion. The third system utilizes a chemical solvent to chemically destroy the data storage portion.

A roof-bolt drill bit may have a forward end, a rearward end, and a rotational axis extending between the forward end and the rearward end. A cutting element for the roof-bolt drill bit may include a cutting face and a peripheral surface extending around an outer periphery of the cutting face. The cutting element may include at least one chamfer region and a peripherally extending chamfer extending from the at least one chamfer region along the outer periphery of the cutting element, a width of the at least one chamfer region being greater than a width of the peripherally extending chamfer.

摘要:
The present disclosure relates to a drilling worktable for manufacturing tube support plates of a steam generator constituting a primary system of a nuclear power plant. The drilling worktable includes a plate (100) having a drill insertion groove (110) formed to face a position at which a heat transfer tube insertion hole is drilled in a member to be processed. In addition, the present disclosure relates to a method of manufacturing tube support plates using the drilling worktable for manufacturing tube support plates. The method includes fixing the member to be processed after locating the member to be processed on the upper surface of the seating section, and drilling the heat transfer tube insertion hole in the member to be processed using a drill unit.
