Size:
Normal Size Range: D(Outer Diameter): 1.5~100mm, d(Inner Diameter): 0.4~80mm,T(Thickness): 0.4~100mm
Maximum Size: D100 x d80mm x T60mm, D80 x d50 x T100mm
Minimum Size: D1.5 x d0.4 x T0.4mm
Orientation Direction Size: Lower than 80mm
Tolerance: Generally +/-0.1mm, Particularly +/-0.03mm
Remarks: Generally speaking, it’s not allowed to have too large outer diameter with too thin thickness or wall thickness, or too small outer diameter with too thick thickness, because SmCo is too brittle and it’s easy to fracture during machining and assemblying. For further guidance, please contact us directly.
Machining Method:
The machining method for the outer diameter is same as that of the cylinder. If the inner diameter is large for example d>4mm, it can go to inner diameter drilling and then slicing. If the inner diameter is small for example d<4mm and the thickness of finished ring is not too thick, it should go to slicing and then go to laser drilling and grinding.
Main Application:
Electric motors, sensors, speakers, magnetic assemblies, etc. |
