GO/NO GO BALL FEELER GAUGE FOR PARTS CHECKING JIGS AND METHOD

摘要

A go/no go ball feeler gauge includes a ball that is laser-welded to a rod. The rod is preferably cut utilizing an EDM process to provide a flat end to which the metal ball is laser-welded. Also, the metal ball is selected to have an initial size that is about 2 microns less than a final required size, and the laser welding process causes the ball to expand to the required diameter.
