\"magneticMy last post mentioned the types of magnetic chucks<\/a>, of which we’re not very aware of their differences and the pros & cons for each magnet chuck. So in this article, let’s make a simple comparison and analysis on their advantages and disadvantages.<\/p>\n

Permanent Magnetic Chuck<\/h6>\n

Advantages:<\/strong>
\nIndependent from electrical power – no danger of dropping piece in a power failure
\nEase of installation for transfer from one machine to another
\nNo generation of heat, which could deform the pole plate or work-piece<\/p>\n

Disadvantages:<\/strong>
\nChuck dimension is less adaptable and thus not suitable for big & heavy work-piece
\nWear and tear on the internal moving parts and magnets will shorten the life of the permanent chuck
\nMechanical switching system inefficient for automated work
\nCannot be used with components at a temperature above 80\u2103<\/p>\n

Electromagnetic Chuck<\/h6>\n

Advantages:<\/strong>
\nNo moving parts inside, thus less internal wear and tear
\nCan be operated with control units which can regulate the magnetic holding force and control the demagnetizing cycle, allowing for easy removal of the metal piece
\nReliable & strong clamping force on rough piece
\nVarious chuck dimensions can be produced, enabling the user to meet the requirements of the workpiece size<\/p>\n

Disadvantages:<\/strong>
\nRequires a constant power supply, and for safety reasons, often needs a back-up power supply as well
\nConstant power also produces heat and cause heat distortion of the parts, which can affect the accuracy of the machining
\nA power failure will cause such a chuck to release a part, potentially causing an accident.<\/p>\n

Electro-permanent Magnetic Chuck<\/h6>\n

Advantages:<\/strong>
\nPower is only needed for magnetization & demagnetization of the chuck
\nNo moving parts inside, thus no internal wear and tear
\nProvides full access to the five sides of a mold – ideal for multi-side machining
\nOperation from a control unit provides the possibility for automated use
\nThere is minimal electricity consumed, and there’s a greater safety factor since a loss of power won’t cause the chuck to release the part
\nNo heat generation – no threat to machining accuracy<\/p>\n

Disadvantages:<\/strong>
\nHigher cost of electro-permanent magnets than permanent magnets
\nHigher sensitivity to air gaps between the chuck and component
\nMagnetic fields and clamping force can be difficult to fine-tune<\/p>\n

So, which type of magnetic chuck is best for surface grinding machine<\/strong>? Just like people says, with every pro comes a con. It’s hard to draw a conclusion that which type is the best for specific machining operation.<\/p>\n

Advice from Electro Permanent Magnetic Chuck Manufacturer<\/strong> – HVR MAG<\/strong><\/a>
\nYou must integrate your specific application requirements with the advantages and disadvantages of each type of magnetic chuck, to make the final decision. Then, furnish the magnetic chuck supplier with all your needs, to get a custom designed magnet chuck<\/a> that best fits your workholding purpose.<\/p>\n","protected":false},"excerpt":{"rendered":"
