Learning Center


DocMagnet believes that the more their clients know about this technology, the more they’ll be convinced that first, magnets have a significant place in the management of steel and second, that DocMagnet is an industry leader. Simon Barton has an extensive background in the design and application of Magnetic Workholding (Magnetic Chucks for milling and turning) and Magnetic Handling (Magnetic Lifters for the conveying of steel).  He and other DocMagnet engineers will write informational and opinion articles here as well as post technical papers and application feasibilities. Visit this section often to obtain the latest in technical expertise in the magnetic material handling and magnetic workholding industries.

Technical Papers

  • Understanding Magnetic Flux Behavior

    Magnetic flux is a measurable quantity of a magnetic field over a given area.  Flux lines are often used to depict the direction of flux as it flows from the north to the south pole of a magnet.  The greater number of these flux lines the greater the density of the flux and ultimately, the […]

  • Switchable Magnets Explained

    A simple electro magnet shown (fig.1) incorporates a coil of N turns wrapped around a ferromagnetic steel horseshoe. Direct current is applied to the coil which creates a magnetic force perpendicular to the coil. Magnetic flux passes through the poles of the horseshoe which will then influence any ferromagnetic material that comes within the field […]

  • A Molders Guide to Magnetic Quick Mold Change Systems

    Having established a need to improve mold changeover time, when deciding upon the clamping process, the molder is confronted by three technology choices.. • Manual-Mechanical – typically for smaller presses.  Involves the mold being modified to accept some kind of clamping ring or spigot.  Specially designed plates are mounted to both platens which through the use […]

  • Using a Magnetic Chuck to Mill a Round Bar Square

    Workpiece Material: Hot rolled 8620 Steel Raw Workpiece Size: 5”diameter x 20” long Magnetic Chuck:  DM-MC-70SP-0406 (16 x 24”) Top Tooling: DM-MC-BP70-5 BACK Parallel Milling a round bar square on a magnet may seem daunting to the uninitiated, but as the following data shows, if managed with the right top tooling, is quicker and more […]

  • Heavy Turning on a Magnetic Chuck

    Magnetic Chucks both electro and permanent types were originally developed for light machining and more specifically for grinding operations.  This form of workholding is the best way of presenting the whole of the workpiece to the grinding wheel and at the same time clamping uniformly and very accurately. Why, therefore, has the same philosophy not spread […]
