Precision
A new ultra-fine piercing which had been proposed, have been conducted successfully, but has a few troublesome points. A die material is mild steel, and than a coupling of a die and a pierced material is that of metals. Therefore, pierced scrap accumulated in a die hole and stops a punch advancement. If the pierced material rises up unevenly from the die, a horizontal force acts on the punch and the punch defects, advances deviately and shaves the surface of the die hole. These were conquered by means of setting a vacuum chamber under the die. A scrap is sucked away from a die hole at each stroke and a foil of pierced material is pulled down through two holes remoted by 1 mm from the die hole. Thus a high precision and continuous process of the ultra-fine piercing is carried out.
