The electric permanent-magnetic chuck is a new type magnetic chuck using electric pulse for "switch On and switch Off" magnetic force. It will result in an endless permanent magnetic attraction, so it's safe and reliable for the chuck to attract workpiece. Time needed for "On/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 machinery. Besides, it's used in accessory holders for processing centers and FMS systems.
