Permanent magnetic clamping plate SPNM is a high precision magnetic plate to clamp small and thin workpieces for precision grinding and EDM. The low magnetic field prevents the magnetization of the machining tools. The clamping plate is operated by a removeable Allen key. Finish: - Neodym-magnetic system - Steel body - Pole pitch 1.4 + 0.5 mm - Nominal holding force 100 N/cm² - Magnetic field height 5 mm - Pole plate wearing limit 6 mm
