Used for electronic signal connectors and connector pins

Tiny pins. Used for electronic signal connectors and connector pins.
In general, the cylindrical shaft surface tolerance can reach 0.01MM (if it is copper can be 0.005MM), the surface roughness can reach 0.8.
Cylindrical centerless grinding, tolerance reached 0.001MM, surface roughness up to 0.2um. This is a non-standard turning part that can not be reached by the cold heading. Tiny machining parts, non-standard lathe turning parts
