Resistance to the implementation of magnetic operate holding normally begins using a concern for security. These concerns could be allayed by assessing the technologies, holding energy and optimal operating circumstances of magnetic work holding when it comes to operational safety.
Regardless of the competitive Workholding advantages of magnetic workholding in decreasing expenses and enhancing productivity, there nonetheless exists a resistance to the implementation of magnetic technology as the major function holder in machining operations. This resistance usually starts using a concern for safety. By assessing the technologies, holding power and optimal operating situations of magnetic function holding relative to operational security, these concerns could be allayed.
Magnetic Function Holding as a Protected Technology
If a machine operator has held workpieces with mechanical clamps for decades, the concept of relying on magnetism to hold workpieces, specially in heavy milling operations, boils down to a problem of trust: Is this actually safe? Though understandable this opinion is rooted in subjectivity not objective reality. More than most likely, people that hold this point of view may not fully comprehend the details of how safe magnetic function holding is.
So, how can magnetic function holding be regarded as as a safe technology? By definition, it produces a uniform, consistent, and infinite holding power that will not relax, give, or decrease until 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 in this flux field, a magnetic field of opposite polarity is induced in to the workpiece thereby generating a magnetic attraction amongst the chuck as well as the workpiece. This attraction will stay constant, uniform, infinite, and reliable as long as the magnetic field is energized. This reliability makes magnetic workholding a actually safe technology.
Magnetic Operate Holding as a Secure Holding Force
Holding energy or strength is another element deemed when forming an opinion about the safety of magnetic workholding. If an operator doesn't understand how strong magnetic workholding is, he may well mistakenly think magnetic technology will not be sturdy sufficient to do the job safely. This opinion could 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 might be generated by magnetic workholders. This level of holding force is more than comparable to mechanical clamps with one particular added advantage: magnetic holding force is uniform, continuous and infinite until the operator de-energizes it.
Optimal Operating Situations
To implement magnetic work holding options may perhaps require some education to understand the technology's optimal operating conditions. By way of example, magnetic perform holding is best made use of with smooth-surfaced workpieces as opposed to rough ones mainly because the smoothness decreases the air gap in between the workpiece and also the magnet; small air gaps raise magnetic attraction as well as the holding bond. Some materials are better conductors of magnetism than others. One example is, annealed supplies are excellent even though hardened supplies never absorb flux as effortlessly and will retain some magnetism. This situation might be corrected within seconds with demagnetization. Finally, the path on the holding force is however one more adjustment an operator might have to produce to safely implement magnetic work holding. All magnets have one hundred percent clamping force straight away in the face in the magnet, but only about 20 % clamping force against side forces. So, the geometry of a cut have to be deemed inside the machining approach to reap the benefits of this type of workholding.
