Magna-Vises: A Solution for Holding Non-Magnetic Materials

Here is an amazing tool that enables your magnetic chuck to grip any rigid, non-magnetic material!

With a Magna-Vise set, you can greatly increase the value of your magnetic chuck by making it possible to hold rigid non-magnetic materials such as brass, copper, plastic, aluminum, etc. They eliminate cumbersome fixtures, reduce set-up time and costs. Easy to use and so valuable to the machinist.

Magna-Vise sets were once mass-produced and sold under various brand names.

These were originally developed and manufactured by Hanchett Magna-Lock Corporation in Big Rapids, Michigan, over seventy years ago. Magna-Vise sets were sold under the Magna-Lock, Brown & Sharpe, and other less popular brand names from the 1950s to the 1980s. They are considered an industry standard for machinist toolboxes, toolmakers, and watchmakers. Many refer to them as Magna-Perms, Magna-Clamps, Perma-Grips, welding clamps, Magna-Grips, and other names we have received inquiries for.

Multiple-sized Magna-Vise sets can be used together to hold larger pieces.

The Magna-Vise set consists of a pair of magnetically actuated clamps so designed that parts made of non-magnetic material may be located between the jaws and held firmly against the face of the magnetic chuck for machining purposes.

The Magna-Vise set greatly increases the value of your magnetic chucking equipment by making it possible to hold rigid types of non-magnetic material such as brass, copper, plastic, glass, hard rubber, aluminum, and stainless steel.

By placing the work on the magnetic chuck surface between the Magna-Vise clamp set so that the toothed edge of each clamp is in contact with the work. A backing plate, against which the back edge of one clamp should be placed, is available on most magnetic chucks.

Each Magna-Vise clamp is composed of two steel sections connected by a preset spring steel strip. The angle of this spring is such that these sections will normally be 5° to each other. When the chuck is energized, the jaws of the clamps are forcibly drawn flat to a horizontal position by the magnet, exerting a powerful lateral thrust against the workpiece. The wedging action of the teeth against the workpiece holds it securely in place against the face of the chuck.

If the Magna-Vise does not pull down completely, tap or push with the fingers until it is in full contact with the chuck surface. Many difficult-to-hold toolroom jobs become easy with Magna-Vise sets. As you continue to use it, you will consider the Magna-Vise invaluable. Each set comes fitted in a protective case.

Three standard sizes of Magna-Vise sets are normally stocked for immediate purchase, including MV-6, MV-6a, and MV-10. The MV-14 is available for special order with minimal lead time. The Magna-Vise principle can be designed into special sizes and shapes, both for the toolroom and automatic production holding for continuous loading and unloading.
