The Permanent magnetic clamping plate SPNM-W has the same magnetic characteristics as clamping chuck SPNM but can be used for horizontal and vertical clamping. SPNM-W are used for the grinding of edges on plates, for grinding angles on plates or for wirecutting. For the use on surface grinding machines, the SPNM-W can be clamped on the electric clamping plate of the machine. Finish: - Neodym-magnet system - Steel body - Pole pitch 1.4+0.5mm - Nominal holding force 100 N/cm² - Magnetic field height 5mm - Pole plate wearing limit 6mm
