It’s a new-type magnetic chuck using electric pulse “ON" or "OFF” magnetic force. It’s quite safe and reliable for the chuck to attract workpiece, which will result in an endless permanent magnetic attraction. Time needed for “ON" or "OFF” is less than one second, which will ensure little electric pulse power consumption and no heat deformation of the chuck. It has no sliding parts as ordinary permanent magnetic chuck, which results in a stable, firm and high-precision structure. To use electric pulse to enforce “ON" or "OFF” of magnetic force will ensure automatic control.
   It’s widely applied to attract workpieces in surface grinders, electric processing machine-tools, as well as in casting, drilling, planning and boring machines. Besides, it’s used in accessory holders for processing centers and FMS systems.

   Electro-magnetic Chuck controller: There are one-way, two-way and four-way channels to be chosen in our company and we can design much more multi-way controllers such as 8-way,16-way according to customers' requirements.
