Size:
Normal Size Range: D(Diameter): 1~150mm, T(Thickness): 0.4~150mm
Maximum Size: D150 x T60mm, D80 x T150mm
Minimum Size: D1 x T0.4mm
Orientation Direction Size: Lower than 80mm
Tolerance: Generally +/-0.1mm, Particularly +/-0.05mm
Machining Method:
Generally the small axially oriented cylinder(<D10mm) and almost all diametrically oriented cylinder is EDM cut from the big block and then grinded and sliced. The big axially oriented cylinder(>D10mm) can be pressed to shape and then grinded and sliced. But sometimes the big axially oriented cylinder should be core-drilled or EDM cut from a block, so as to ensure the magnetic properties especially for high end grades or shorten the lead time. Prior to coating, the small cylinder needs viabration tumbling and the big cyliner needs manual chamfering.
Main Application:
High speed electric motors, sensors, magnetic sputtering cathodes, magnetic assemblies, etc.
