Here is an amazing tool that enables your magnetic chuck to grip any rigid type of 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.
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 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 many more names that we have received inquiries for.
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 work piece. The wedging action of the teeth against the work piece 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. East 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 are available for special order with a 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.
