These electro permanent magnet chuck only require a momentary pulse of electricity from the controller to energize or de-energize.
Once energized, the magnets are “ON” and their clamping ability will not be affected by electrical power failure or cut cables. that is to say, the magnet clamping will not loss power due to loss of electricity
HVR Company compensated magnet circuit design allows the switching process to be performed without the use of internal moving parts.  Because the magnets have no internal moving parts, they can be rigidly encapsulated and sealed so that no dust or particles can enter and create a problem over time.

Features：

1 Super Power Magnetic Force 1600KG/100CM2

2 1~3 Seconds controller for power On& OFF, No Electric Power Supply Required to Keep the magnetic chuck on, in other words, safety in case of power failure.

3 No Power Supply to keep the magnetic chuck on, it could be used for long time and never get temperature to affect the accuracy of work piece

4 Can do 5 sides machining, un obstructed movements of cutters during marching, one cycle to finish a work piece, helps in achieving best machining accuracy and increase efficiency a lot.

5 easy and convenient to clamp a work piece, shorten clamping time

Application

1 Most Suitable for machining on Medium & Small or Even rough Work piece

2 Suitable for Drilling and finishing machining on small work piece
