Metal Spinners
During the process of metal spinning, the metal spinner applies pressure to the rotating blank using several tools to shape the metal over a form called a chuck or mandrel. This pressure can be applied by a single tool or by multiple levers hydraulically. The finished product, if produced correctly, has no wrinkling or warble due to the high speed of rotation around the mandrel. The process is quick and cost efficient and changing the spinning shape requires merely replacing the mandrel.
When choosing a metal spinner it is important to note its output capability. Some shops are not capable of short run orders and may have limitations as to the diameter and thickness of final product desired. Other times a manufacturer will only have the capacity to spin a certain type of metal, such as stainless steel or aluminum. The metal spinning business continues to grow as the process becomes more improved through technological advances.
Common types of metal spinners include CNC machine spinners, custom metal spinners, hand metal spinners, and stainless steel metal spinners. CNC machine spinners and related technology are most often used during the metal spinning process due to their ability to produce high volume, close tolerance, concentric metal parts quickly and economically. Currently, the majority of shops who perform metal spinning services use custom metal spinners. Because of flexible rapid tooling and the short set up times associated with the technique, the costs of metal spinning can be much lower than other metal fabrication techniques. Although stainless steel is the material most often used in metal spinners, most shops are capable of spinning a wide range of common to exotic metals, including aluminum, brass, copper, hastelloy, and titanium.
