From surface grinding to broader application in general metalworking processes, holding metal parts with magnets is migrating especially milling. Many shops to re-evaluate how they hang on to workpieces are caused by advances in magnetic technology. Here’s a look at how your shop magnets may be a viable work holding solution.

A mix of a combination of art and science is the metalworking craft. The science is represented by the tools available to the machinist. In their application is art.

In the metalworking shop, the science behind Magnetic Chuck China is fairly basic. To allow metalworking processes such as grinding, turning, milling, or drilling to be performed, Hang on to the forging, casting, or blank to be machined, with sufficient grip.

Used to accomplish the basic science, the metalworker’s art in work holding is the myriad ways. Traditionally many variations of mechanically securing the workpiece are involved in most work holding methods.

For holding work holders and for machining such as fixtures and vises on the ...
... machine tool table In recent years, Magnets have entered the work holding fray as an alternative to mechanically holding workpieces. Magnets are finding acceptance in general machine shops looking to simplify their approach to work holding, increase access to the five sides of a workpiece, and reduce setup.

Basics of Magnets

Ferrous materials are attracted by magnets. Across which flows magnetic energy called flux Magnets have a south and north pole.
One can actually see in the classic experiment using iron filings in roughly parallel arcs between the two poles, by the arrangement of the filings that the magnetic flux flows. By inducing polarity (magnetizing) into any ferrous material basically, magnets work that connects across its poles. The flux flows into it when a workpiece is placed across the poles of a magnet.

Ferrous components when placed in the magnet flux have poles that are opposite the polarity of the magnet. Hence, they attract. To applying magnets in a metalworking operation, the key is Amplifying and controlling this flux.

As the gap between the workpiece and the magnet closes, the attraction or pull of the magnet becomes stronger. Held than rough-surfaced, smooth-surfaced workpieces are more tightly. A function of how much magnetic flux of Neodymium Magnets can be induced into the workpiece is the strength of the magnetic attraction.

Some materials than others are better conductors of magnetism. Annealed materials are best. Hardened materials easily don’t absorb flux and when the magnetic work holder is switched off tend to retain some magnetism.

Permanent magnets offer the advantage of fail-safe and portable operation. Within a carrier, most industrial permanent magnets sit. The state of the magnet is determined by the Alignment of the poles. In operation, to de-activate and activate the permanent magnet, these poles are physically moved.

A series of magnetic poles are present in the magnetic work holder. In general the stronger the magnetic grip the more of these poles engage a given workpiece.
