Heading: A coil of wire is cut to the required length and each piece compressed and shaped into balls using a pressing machine.
Flashing: The surface of the balls is ground to remove the bands generated in the heading process.
Heat treatment: After the bands have been removed, the balls are quenched adn tempered to give them sufficient strength and durability.
Grinding: In addition to removing parts decarburized in the heat treatment, this process adjusts dimensional precision and finishes the balls to the stipulated dimensional difference.
First lapping: The dimensional precision of the balls is further improved and they are finished to the specified dimensional difference.
Second lapping: In addition to increasing the balls' dimensional precision to grade level, this process gives the surface of the balls a smooth, glass like finish.
Visual inspection: All of the finished steel balls and all of their surface visually inspected automatically. These visual inspection ensure that the balls supplied to customers have no flaws.
