Despite the competitive more info benefits of magnetic workholding in decreasing costs and enhancing productivity, there still exists a resistance to the implementation of magnetic technology as the primary perform holder in machining operations. This resistance generally begins using a concern for safety. By assessing the technology, holding power and optimal operating circumstances of magnetic work holding relative to operational security, these concerns can be allayed.

Magnetic Work Holding as a Secure Technology

If a machine operator has held workpieces with mechanical clamps for decades, the idea of relying on magnetism to hold workpieces, especially in heavy milling operations, boils down to an issue of trust: Is this definitely secure? When understandable this opinion is rooted in subjectivity not objective truth. More than probably, those who hold this point of view may not totally recognize the information of how secure magnetic operate holding is.

So, how can magnetic operate holding be viewed as as a secure technologies? By definition, it produces a uniform, consistent, and infinite holding power that does not relax, give, or reduce till an operator de-energizes it.

Generally, magnetic function holders are constructed with an array of individual magnets embedded into a magnetic chuck or plate. Every magnet includes a north and south pole across which flows magnetic energy referred to as flux. When a workpiece is placed across the poles of those magnets, flux flows into it. When placed within this flux field, a magnetic field of opposite polarity is induced in to the workpiece thereby building a magnetic attraction among the chuck plus the workpiece. This attraction will remain constant, uniform, infinite, and reliable as long as the magnetic field is energized. This reliability tends to make magnetic workholding a truly protected technology.

Magnetic Perform Holding as a Protected Holding Force

Holding power or strength is one more element regarded when forming an opinion regarding the safety of magnetic workholding. If an operator will not know how strong magnetic workholding is, he may mistakenly think magnetic technologies just isn't strong adequate to perform the job safely. This opinion might be allayed by two details:

(1) magnetic workholding can have a clamping power as much as 1000 daN and

(two) based upon the application, an instantaneous clamping force of 12 tons per square foot can be generated by magnetic workholders. This level of holding force is greater than comparable to mechanical clamps with 1 more advantage: magnetic holding force is uniform, constant and infinite until the operator de-energizes it.

Optimal Operating Situations

To implement magnetic operate holding options may possibly call for some coaching to understand the technology's optimal operating conditions. One example is, magnetic function holding is most effective employed with smooth-surfaced workpieces rather than rough ones due to the fact the smoothness decreases the air gap in between the workpiece plus the magnet; little air gaps enhance magnetic attraction and also the holding bond. Some components are far better conductors of magnetism than others. One example is, annealed components are perfect when hardened components do not absorb flux as quickly and can retain some magnetism. This condition can be corrected inside seconds with demagnetization. Finally, the path with the holding force is but one more adjustment an operator might have to create to safely implement magnetic function holding. All magnets have 100 percent clamping force straight away in the face from the magnet, but only about 20 % clamping force against side forces. So, the geometry of a cut have to be thought of inside the machining procedure to reap the benefits of this type of workholding.
