  • Manufacturing method for an electronic part absorbing nozzle
    Patent number: 6282787
    Abstract: A nozzle rod is formed by fixing a thick diamond chip to a tip of a nozzle pipe made of a super hard metal, the other end of the nozzle pipe is thinned and the nozzle rod is joined with a shank by way of this end, a tip of the nozzle rod and vicinities thereof are so shaped as to have a predetermined sectional shape, a center hole is formed in the diamond chip by wire electro spark machining and expanded for forming a nozzle slot having a nozzle opening consisting of a center slit and “U-shaped” slits which are disposed symmetrically on both sides of a longitudinal direction of the center slit, thereby composing an electronic part adsorbing nozzle. This construction enables it to provide an electronic part adsorbing nozzle which is economical and excellent in durability.
    Type: Grant
