Document Type and Number:
Japanese Patent JP2008110360
Kind Code:
A
Abstract:
To provide a method for manufacturing metal balls, capable of efficiently manufacturing the metal balls without heating a stock.
The method for manufacturing metal balls enables the molding of the metal balls from a long-shaped material S by cold-rolling the material while using at least a set of molding rolls 30, 30. The material S is arranged so as to elongate along an axial line L. Ball materials are manufactured from the stock S by rotating each of the set of molding rolls 30, 30 on its rotation axis M respectively and further revolving each of the set around the axial line L along the outer peripheral surface of the stock S.
