Abstract

PURPOSE: To improve the productivity, by performing a processing work of burring lower hole in the top plate, then after processing a chamfering work in an end face of this lower hole, uniformly constructing the main lens electrode in the method of burring work.
CONSTITUTION: In a top plate 12 of the electrode main unit 11, is constructed a burring lower hole 14 by the method likely of punching works. Subsequently in an end face 15 of this lower hole 14, by using a coining punch 17 with a chamfering part 16 provided, is formed a chamfered part 18 by processing a coining work. Further with a coining work applied, a burring work is processed by using a burring punch 19 from the end face-processed side. In this way, a lens portion, with a burring height fully provided in point of performance, being made uniformly formable, the process of construction is simplified, and an improvement of both tubulousness and roundness can improve the percision of assembly.
