Size:
Normal Size Range: D(Outer Diameter): 1.5~150mm, d(Inner Diameter): 0.4~100mm,T(Thickness): 0.4~150mm
Maximum Size: D150 x d100mm x T60mm, D80 x d60 x T150mm
Minimum Size: D1.5 x d0.4 x T0.4mm
Orientation Direction Size: Lower than 80mm
Tolerance: Generally +/-0.1mm, Particularly +/-0.05mm
Machining Method:
The machining method for the outer diameter is same as that of the cylinder. And then it goes to inner diameter drilling and then slicing. Prior to coating, the small ring needs viabration tumbling and the big ring needs manual chamfering.
Main Application:
Electric motors, sensors, speakers, magnetic assemblies, etc.
