Electric permanent magnetic chucks can generate a powerful suction as high as 16kg/cm², which will not decay with the extension of time. The magnetic lines of force are evenly distributed within the entire contact area between the molds and the chucks. The depth of the magnetic action is within 16mm. The magnetic lines of force will not penetrate the surface of the workpiece to be processed, will not magnetize the cutting tools and the main shaft of the machine tool, and will not affect the processing accuracy and chip removal.

All contact points between workpieces and electric permanent magnetic chucks or magnetic conducting blocks are support points and clamping points, making the clamping more stable, with better rigidity and better anti-vibration performance, suitable for high-speed cutting. The service life of cutting tools can be extended by more than 30%. Under the action of automatically leveling magnetic conducting blocks, internal stress and clamping deformation will not be generated in workpieces. After processing is completed, workpieces will not rebound and deform. Multi-sided processing does not require repeated clamping, and the accuracy is higher.
