The pierced billet or hollow shell is rolled by a mandrel mill to reduce the outside diameter and wall thickness which forms a multiple length mother tube. The mother tube is reheated and further reduced to specified dimensions by the stretch reducer.
A comprehensive guide for reducing the cost of your custom metal and plastic CNC machined parts. Learn how to optimize your design and choose the right material to keep your project on budget. Whether you are looking to create a single prototype or you are ready for …
We can construct solid knits that are completely stable or we can design solid knits with a great deal of stretch in width, length or bias. Solid knits breathe. Even the densest, most solid appearing knits have tiny openings, allowing the flow of air.
We discuss the roll pass design methods of stretch reducing mill, focusing on analyzing the oval pass and round pass design ideas, and based on previous research results, select the rolling force, rolling moment and the temperature drop models.
At Altamont Pass near Livermore, California, thousands of lattice-tower turbines (above) are being replaced in an effort to boost efficiency and reduce deaths.
