The Manufacture of Steel Balls (Classic Reprint)

Book excerpt: Excerpt from The Manufacture of Steel Balls Several other ball companies had no good blanking process, and, therefore, hired men who understood the rolling process from the Simonds Co. A number of machines were thus designed similar to the Simonds type. One of these had circular platens instead of straight ones, and was made with circular dies, one within the other. The die holders, of course, were running in opposite directions. This machine worked satisfactorily, but the dies were much more difficult to make on account of their circular shape, and also on account of the fact that the inner die was smaller than the outer. The company designing this machine did not have a good grinding process and the machine was, therefore, soon abandoned on account of discontinuing the manufacture of balls.
