Adopts the principle of bipolar magnetic difference, and the permanent magnetic device controlled by the transient pulse current. Because the rare earth permanent magnetic material is used as the main magnetic pole, it has huge magnetic force and maintains the stability of magnetic force for a long time.
The electric permanent magnet chuck does not need electric energy in the work, only relies on the permanent magnet suction to hold the workpiece, avoiding the danger of the workpiece falling off due to the loss of magnetic force when the electromagnetic chuck is suddenly powered off and the dragging line is damaged. The use method of the electric permanent magnet chuck is very simple and fast. There are no moving parts in the fixture system, which is reliable, durable and practical.
The conversion process of magnetizing and demagnetizing takes only 1-2 seconds, and the efficiency of clamping and loosening the workpiece is very high. Strong suction and low remanence.
Power off without loss of excitation, safe to use. Small thermal deformation, no moving parts, long service life and reliable operation. Convenient card loading and labor saving.
Five-face machining, no knife blocking phenomenon, matching with the magnet can also be chamfered on the bottom. The suction cup adopts an integral structure with high rigidity and stability.
The large-capacity suction cup adopts dual-element control circuit and phase balance, so the higher harmonic is very small and does not interfere with other equipment. The suction of the suction surface after excitation shall not be less than 28 kg per square centimeter.
