Skew Rolling


The ability to manufacture metal spheres with very accurate dimensions and surface quality is important in modern industry. One of the main applications of these metal balls is for the ball mills. One of the main ways that these metal spheres are manufactured is by skew rolling. Skew rolling is a metal forging process that uses two specially designed opposing rolls, that rotate continuously. Round stock is fed into the rolls, the material is forged by each of the grooves in the rolls and emerges from the end as a metal ball. The stock is fed through the rolls continuously, but each ball is produced separately, thus it is a discrete process and not a continuous one. Skew rolling, similar to roll forging, is a manufacturing process that bears qualities of both metals rolling and metal forging.
