Magnetic Operate Holding as a Secure 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? Even though understandable this opinion is rooted in subjectivity not objective truth. More than most likely, people that hold this point of view may not completely realize the details of how protected magnetic perform holding is.
So, how can magnetic operate holding be regarded as a safe technology? By definition, it produces a uniform, constant, and infinite holding power that doesn't relax, give, or reduce till an operator de-energizes it.
Generally, magnetic work holders are constructed with an array of person magnets embedded into a magnetic chuck or plate. Each magnet includes a north and south pole across which flows magnetic energy known 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 generating a magnetic attraction involving the chuck plus the workpiece. This attraction will stay consistent, uniform, infinite, and dependable as long as the magnetic field is energized. This reliability tends to make magnetic workholding a definitely secure technologies.
Magnetic Operate Holding as a Protected Holding Force
Holding power or strength is a different aspect thought of when forming an opinion in regards to the security of magnetic workholding. If an operator doesn't know how strong magnetic workholding is, he could mistakenly think magnetic technology is not sturdy enough to complete the job safely. This opinion could be allayed by two information:
(1) magnetic workholding can possess a clamping power as much as 1000 daN and
(2) based upon the application, an instantaneous clamping force of 12 tons per square foot could be generated by magnetic workholders. This level of holding force is greater than comparable to mechanical clamps with a single additional advantage: magnetic holding force is uniform, continuous and infinite till the operator de-energizes it.
Optimal Operating Conditions
To implement magnetic function holding solutions might call for some coaching to know the technology's optimal operating situations. For example, magnetic perform holding is very best used with smooth-surfaced workpieces instead of rough ones because the smoothness decreases the air gap amongst the workpiece and also the magnet; modest air gaps boost magnetic attraction and also the holding bond.
