Resistance for the implementation of magnetic work holding ordinarily begins using a concern for security. These issues may be allayed by assessing the technologies, holding power and optimal operating situations of magnetic function holding when it comes to operational security.
Regardless of the competitive full article positive aspects of magnetic workholding in reducing charges and improving productivity, there nevertheless exists a resistance towards the implementation of magnetic technology as the major work holder in machining operations. This resistance commonly starts having a concern for safety. By assessing the technology, holding power and optimal operating situations of magnetic function holding relative to operational safety, these concerns is often allayed.
Magnetic Work 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 truly protected? When understandable this opinion is rooted in subjectivity not objective reality. Greater than probably, individuals who hold this point of view may not totally comprehend the details of how safe magnetic function holding is.
So, how can magnetic work holding be considered as a secure technology? By definition, it produces a uniform, constant, and infinite holding power that will not unwind, give, or reduce until an operator de-energizes it.
Normally, magnetic operate holders are constructed with an array of person magnets embedded into a magnetic chuck or plate. Each magnet has a north and south pole across which flows magnetic power 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 into the workpiece thereby making a magnetic attraction in between the chuck along with the workpiece. This attraction will remain constant, uniform, infinite, and trusted so long as the magnetic field is energized. This reliability tends to make magnetic workholding a really safe technologies.
Magnetic Perform Holding as a Safe Holding Force
Holding power or strength is yet another factor considered when forming an opinion about the safety of magnetic workholding. If an operator doesn't understand how sturdy magnetic workholding is, he may possibly mistakenly believe magnetic technologies is not strong sufficient to do the job safely. This opinion might be allayed by two facts:
(1) magnetic workholding can have a clamping power up to 1000 daN and
(two) depending upon the application, an instantaneous clamping force of 12 tons per square foot is usually generated by magnetic workholders. This degree of holding force is more than comparable to mechanical clamps with 1 extra advantage: magnetic holding force is uniform, continuous and infinite until the operator de-energizes it.
Optimal Operating Conditions
To implement magnetic work holding solutions may call for some instruction to understand the technology's optimal operating circumstances. For instance, magnetic function holding is ideal made use of with smooth-surfaced workpieces instead of rough ones mainly because the smoothness decreases the air gap in between the workpiece along with the magnet; modest air gaps enhance magnetic attraction and the holding bond.
