I need help here.
I drew a quick sketch. I puk the wire, shows in drawing<1>, then wire turns to balls on both side, then I flat the balls and emery the surface, make the surface flat. The workpiece looks like drawing<2> after emery and polish.
The problem is after polish, the wire shows up, I see a little circle which is the wire point, the surface looks like drawing<2>. I want to know how to make the circle disappear.
Anyone please help. Thank you
