  • 8 Advantages of Magnetic Workholding

    So many choices! One would think that having so many choices would be a benefit of living in these times, but when it comes down to making a final decision, the overabundance of options can often be a hurdle in itself. Whether it’s choosing which car to buy, or even which movie to watch, you try to weigh the pros […]

  • Just Another Patent…

    Docmagnet Inc. is proud to announce that their application for a patent that fully acknowledges their exciting development of “Variable Field Technology”(VFT) was granted by the USPTO last month (# 8,907,754). Further applications are in process for other parts of the world (Europe and Asia). Ordinarily, the depth of the magnetic field from a magnetic holding […]

  • Why is Workholding Always Put on the Back Burner?

    Post written by: Ed Kroliczak, Director of Sales I was at a customer site recently showing off our newest magnetic workholding chuck for milling, the Multi-Flux system. The operator and production engineer were impressed by the new magnet and its features, and we began to discuss the different ways their company tries to improve production, […]

  • Magnetic Fixture Design and Cost Considerations

    A magnetic chuck is nothing more than an assembly of steel and magnetic materials used for creating a force. This brief paper will help to illuminate some design aspects of magnetic chucks and how they relate to the cost. There are three primary classes of magnetic chucks: permanent magnetic chucks (manually actuated), electromagnetic chucks, and […]

  • 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

    Electro Magnets 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 […]

    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 […]
