ABSTRACT:
A lead cutting apparatus for cutting the leads or pins of electric and electronic devices into a predetermined length in the manufacturing process including inclined pressing surface(s) and cutting edge(s) for cutting the leads, which are covered with an anticorrosive coat, at a cutting position. The inclined pressing surface(s) is at an appropriate angle relative to the length of the leads and presses, between the pressing surface and an opposite inclined or non-inclined pressing surface, the leads near the cutting positions, thus cutting the leads into a shape that becomes gradually thinner to a very small thickness. The cut ends of the leads are covered with the anticorrosive coat and thus prevented from rusting without requiring any anticorrosive treatment. Accordingly, the manufacturing cost of the electric and electrical devices can be reduced greatly.
