The invention relates to an automated punching station for the production of punched components for prosthetic surgery instruments, in particular for instruments able to mill/cut or otherwise carry out tissue removal processes in preparation for, or in the context of, prosthetic surgery operations. The invention also concerns a method to produce said punched components, and a punched component thus obtained.

To provide a pipe drilling tool for forming, in a pipe, a hole for injecting a non-oxidizing gas such as nitrogen, when joining pipes such as refrigerant pipes by brazing, wherein the pipe drilling tool has a compact configuration allowing work thereof to be performed by the drilling tool being gripped by the hand of a user, does not readily generate burrs, and prevents cutting residue and burr residue from remaining in the pipe.

Systems, methods, and devices for perforating louver perforations into a pipe are contemplated. Systems, methods, and devices for transporting pipes for perforation are contemplated. Systems, methods, and devices for performing quality control inspections of such perforations contemplated. A pipe may be oriented vertically and raised over a device that punches perforations into the pipe from the inside of the pipe toward the outside of the pipe. Various supports may contact the pipe for stabilization and to facilitate the formation of perforations without removing cut away pieces from the pipe. Electronic monitoring of the features of the pipe facilitate quality control inspection during processing. In this manner, a structurally robust pipe having a series of louver perforations along the pipe may be formed.

A method of manufacturing a banjo bolt including a shaft portion including a vertical hole provided in the shaft portion and extending in a first direction, includes forming a first lateral hole and a second lateral hole by processing the shaft portion from a first side in a second direction crossing the first direction, the first lateral hole extending in the second direction and connecting an outside of the shaft portion and the vertical hole, the second lateral hole being located on an opposite side of the first lateral hole with respect to the vertical hole and extending in the second direction and connecting the outside of the shaft portion and the vertical hole, the second lateral hole being larger than the first lateral hole and overlapping the entire first lateral hole when viewed along the second direction, and forming a third lateral hole by processing a portion of the shaft portion where the first lateral hole is formed from a second side in the second direction through the second lateral hole, the third lateral hole being larger than the first lateral hole and similar to the second lateral hole when viewed along the second direction.
