.... The smaller the mesh size, the better and more accurate the simulation's results will be. Because of the massive amount of variables in ring rolling and the transformation the ring undergoes in each revolution, a fine mesh simulation of a single rotation of even a simple design ring would take days to...

... roughness of dies is usually attained easily, regardless of the tool steel selected. Required finishes for fine-pitch threads can be obtained most economically by using A2 and either machining or grinding the die threads. As a short-term solution for a deficient die setup, which is the cause of most early...

... the end, often as a finished bolt. Nut formers have a transfer mechanism that rotates the blank 180° between one or two dies or all the dies. Therefore, both ends of the blank are worked, producing workpieces with close dimensions, a fine surface finish, and improved mechanical characteristics. A...
