In spite of the competitive teco workholding advantages of magnetic workholding in decreasing costs and improving productivity, there still exists a resistance towards the implementation of magnetic technologies because the main operate holder in machining operations. This resistance commonly begins using a concern for security. By assessing the technology, holding power and optimal operating situations of magnetic work holding relative to operational security, these concerns can be allayed.
Magnetic Operate Holding as a Safe 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 genuinely safe? When understandable this opinion is rooted in subjectivity not objective reality. More than most likely, people who hold this point of view might not totally realize the facts of how protected magnetic perform holding is.
So, how can magnetic perform holding be viewed as as a secure technologies? By definition, it produces a uniform, constant, and infinite holding power that doesn't loosen up, give, or reduce till an operator de-energizes it.
Generally, magnetic operate holders are constructed with an array of individual magnets embedded into a magnetic chuck or plate. Every magnet features a north and south pole across which flows magnetic energy called 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 into the workpiece thereby making a magnetic attraction between the chuck as well as the workpiece. This attraction will remain consistent, uniform, infinite, and trustworthy so long as the magnetic field is energized. This reliability makes magnetic workholding a truly secure technologies.
Magnetic Operate Holding as a Secure Holding Force
Holding power or strength is yet another issue deemed when forming an opinion about the security of magnetic workholding. If an operator does not know how powerful magnetic workholding is, he could mistakenly think magnetic technology is not strong enough to accomplish the job safely. This opinion could be allayed by two details:
(1) magnetic workholding can possess a clamping power up to 1000 daN and
(2) depending upon the application, an instantaneous clamping force of 12 tons per square foot can be generated by magnetic workholders. This degree of holding force is greater than comparable to mechanical clamps with one added benefit: magnetic holding force is uniform, continual and infinite till the operator de-energizes it.
Optimal Operating Circumstances
To implement magnetic function holding options might call for some coaching to know the technology's optimal operating situations. As an example, magnetic operate holding is best used with smooth-surfaced workpieces as an alternative to rough ones since the smoothness decreases the air gap among the workpiece and also the magnet; smaller air gaps raise magnetic attraction as well as the holding bond. Some materials are greater conductors of magnetism than other individuals. For example, annealed components are perfect when hardened materials do not absorb flux as simply and can retain some magnetism. This condition might be corrected within seconds with demagnetization. Finally, the path from the holding force is but an additional adjustment an operator may have to produce to safely implement magnetic perform holding. All magnets have 100 percent clamping force directly away from the face of your magnet, but only about 20 percent clamping force against side forces. So, the geometry of a reduce must be thought of in the machining procedure to reap the positive aspects of this sort of workholding.
