Abstract:
An adapter device (10) is described for operating a tap (1), wherein there are provided at least one support element (20) that can be mounted in an axially variable position with respect to the tap body and at least one operating stem (30) fitted in an axially fixed position on the support element (20) with possibility of rotation with respect to the same.
Abstract:
The invention concerns a device for deburring the edges of bores, the device having a basic body (1) with at least one recess (9) which is directed transversely to the longitudinal axis of the basic body and in which at least one blade (8) is disposed so as to be displaceable in a spring-loaded manner in the longitudinal direction of the recess (9). Disposed in the longitudinal bore in the basic body (1) is a pressure spring (5) which abuts one end of a guide bolt (7) whose other end engages in a guide recess (10) which is provided in the blade (8) and exerts at least retaining force on the blade in the direction of displacement (20, 20').
Abstract:
A cutting tool (20) for a lineal milling machine has a female tapered surface (26) for close tolerance matching to the outer, male tapered surface (32) on the outside of the spindle (22) which mounts the cutting tool (20) to provide the maximum width of support for the cutting edge (46). The cutting edges (46) comnprise a plurality of carbide inserts (48), each with its own flute (50) formed in the body (24) of the tool, such that as the cutting tool (20) is rotated at high speed an annulus of cutting surface is created which is ideally suited for use with the following method. A new method for lineal machining includes the steps of advancing the cutting tool (20) into the workpiece to form a substantially accurate edge, retracting the cutting tool (20) from the workpiece, indexing the cutting tool (20) to an overlapping position, and then advancing the cutting tool (20) into the workpiece to remove the amount of overlap, with those steps being repeated to mill pocket openings or for any other lineal milling application.
Abstract:
This document provides orthopedic and dental devices and methods for their use. For example, novel bone drills and dental drills are described. The bone and dental drills have at least some centers of mass that are offset from the drills' axis of rotation. Accordingly, the bone and dental drills may rotate and cut using a precessional pattern of motion. The design facilitates bone cutting, chip formation and hauling capacity, irrigation and bone harvesting. In some embodiments, the bone chips are collected in a removable apparatus fixed to the distal portion of the drill, and the collected bone chips can be used for bone grafting.
Abstract:
Ein Einlippenbohrer (2, 3) mit wenigstens einer an einem Bohrkopf (21, 31) ausgebildeten Schneide (211, 311) weist eine Spanfläche (21, 213) auf, die über mindestens 75 % ihrer Breite und im Wesentlichen über ihre gesamte Länge bis einschließlich zu der Schneide (211, 311) hin konkav ausgebildet ist.
Abstract:
A grounding clamp is provided that includes a grounding wire having two ends that are each configured to extend out an opening in a coaxial cable. The grounding clamp includes a housing configured to receive both ends of the extending wire in an inner chamber through a first opening, the housing including a second opening configured to receive a lug, wherein the lug is configured to secure both ends of the grounding wire within the inner chamber. A method of installing a grounding clamp includes attaching a fishline to a grounding wire and inserting the fishline through an opening of a corrugated coaxial cable in a valley located between an outer conductor and an outer jacket of the coaxial cable, wherein the fishline is rigid enough that it does not buckle or deform significantly under the pressure of the outer conductor and the outer jacket, wherein the fishline is flexible enough that it bends around the corrugated coaxial cable. A drill bit for creating an opening in a coaxial cable is also contemplated, along with a tool for fishing the grounding wire through the coaxial cable.
Abstract:
A cutting element including a cutting face and a longitudinal axis passing through the cutting face. The cutting element includes at least a first portion of the cutting face that is angled at an angle of about 81 to about 89 degrees relative to the longitudinal axis of the cutting element. The cutting element can further include a substrate, a superabrasive an interface between the substrate and superabrasive layer. Further, the cutting face is provided with a surface roughness of 40 microinches or less.
Abstract:
Die vorliegende Erfindung betrifft eine Schneidkluppe sowie einen Halter und einen Schneideinsatz für eine solche Schneidkluppe. Es wird eine Schneidkluppe (1) vorgeschlagen mit einem kreisringförmigen Halter (2) mit am Innenumfang (23) angebrachten, in axialer Richtung verlaufenden Aufnahmenuten (24) mit einem Aufnahmenutprofil zur Aufnahme jeweils eines Schneideinsatzes, mehreren in jeweils einer Aufnahmenut (24) des Halters (2) angeordneten Schneideinsätzen (3), wobei jeder Schneideinsatz (3) an einer zur zentralen Halterlängsachse (4) gerichteten Schneidfläche (32) mindestens eine Schneide (33) und an der gegenüber liegenden Haltefläche (31) ein Halteprofil aufweist, wobei das Aufnahmenutprofil der Aufnahmenuten (24) und das Halteprofil der Schneideinsätze (3) derart miteinander zusammenwirken, dass ein Schneideinsatz (3) beim Einsetzen in seine Aufnahmenut (24) in axialer Richtung (z) geführt wird und in vollständig eingesetztem Zustand in radialer Richtung (r) geklemmt ist, und einem Haltemittel (51, 52) je Schneideinsatz (3) zum axialen stirnseitigen Fixieren des jeweiligen Schneideinsatzes (3) in der Aufnahmenut (24).
