20120079918 | METHOD AND DEVICE FOR PRODUCING LONGITUDINAL COMPONENTS OF METAL WITH HELICAL GROOVES, IN PARTICULAR SPIRAL DRILL BITS OR SCREWS - A device and associated methodology for producing longitudinal components of metal with helical grooves, in particular spiral drill bits or screws, is provided. The method is suited for mass production and improves the cost effectiveness of production. The method includes providing at least one cold forming stage in which a blank is inserted in a guide mold and cold formed in a split mold with at least two movable jaws. The inner wall of the jaws includes at least one section with a contour designed as a negative of the helical grooves. By a heading tool which is movable in axial direction and which engages the free end of the blank positioned in the guide mold, the blank is pressed at least partially through the central opening of the closed split mold. Thus, helical grooves are produced during the contact with the mold contour by plastical cold forming. | 04-05-2012 |
20120266725 | Computerized, Segmented Steel Rule Type Die Making System and Method - A steel rule die making system produces a steel rule dies having an operative surface that form creases and cut patterns in a sheet material to form a box blank. The system includes a die manufacturing station having an indexing bench that securely holds a substrate. At least one slug driver device is disposed adjacent the die manufacturing station to drive the penetrating point of a slug into the substrate. The upper surface of the slug head defines a segment of the operative surface of the steel rule die. | 10-25-2012 |

20130263700 | Longitudinally Ground File Having Increased Resistance To Torsional and Cyclic Fatigue Failure - A method of producing an endodontic file that involves grinding in a plane substantially parallel to the longitudinal axis of a rotating dental instrument blank. By grinding the dental instrument blank in this manner, the torsional strength of the resulting endodontic file is not eroded during its production, thereby providing a file that is less susceptible to breakage during its use. | 10-10-2013 |
