Permanent magnetic clamping

SPREITZER offers rectangular and round permanent magnetic chucks

The magnetization is achieved by mechanically shifting the poles located inside (North/South) by turning the operating key. In this process, the magnets opposite the north & south poles are arranged in such a way that the magnetic flux lines are diverted across the surface. The stepless holding force generation arises. The clamping force is consistent, without magnetic leakage and can be adjusted stepplessly.
