Magnetic Perform 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, specifically in heavy milling operations, boils down to a problem of trust: Is this seriously protected? Although understandable this opinion is rooted in subjectivity not objective truth. Greater than likely, individuals who hold this point of view may not fully recognize the information of how secure magnetic perform holding is.
So, how can magnetic work holding be viewed as as a safe technologies? By definition, it produces a uniform, constant, and infinite holding power that doesn't unwind, give, or decrease till an operator de-energizes it.

Magnetic Perform Holding as a Safe Holding Force
Holding power or strength is yet another element regarded when forming an opinion concerning the security of magnetic workholding. If an operator will not know how robust magnetic workholding is, he may well mistakenly think magnetic technologies just isn't robust adequate to accomplish the job safely. This opinion might be allayed by two details:
(1) magnetic workholding can have a clamping energy as much as 1000 daN and
(2) based upon the application, an instantaneous clamping force of 12 tons per square foot is usually generated by magnetic workholders. This amount of holding force is greater than comparable to mechanical clamps with one particular added benefit: magnetic holding force is uniform, constant and infinite till the operator de-energizes it.
Optimal Operating Conditions
To implement magnetic work holding solutions may possibly need some coaching to know the technology's optimal operating circumstances. For instance, magnetic work holding is finest utilised with smooth-surfaced workpieces rather than rough ones for the reason that the smoothness decreases the air gap between the workpiece and the magnet; modest air gaps increase magnetic attraction and the holding bond.
