CNC (Computer Numerical Control) metal spinning machine is a sophisticated industrial tool used in metalworking processes to create cylindrical or conical shapes from flat metal discs or blanks. This manufacturing technique, also known as spin forming or metal turning, utilizes precision-controlled rotation and shaping tools to form metal parts. CNC technology has revolutionized metal spinning by enabling high levels of automation, accuracy, and repeatability in production.

Running one of these machines involves many steps, and the operator needs to be aware of the oncoming process to plan the intermediate steps. When the final work is finished, the workpiece is removed, and the dies are prepared for final component removal. Typical components include light fixture parts, aluminum cooking pots, base plates, satellite ground station components, and many other specially shaped items which sell to the customer at high prices. The process is relatively economical once the proper machine and tooling combination is chosen. Continuing sheet and coil developments have kept the Boys very busy continuing to adapt these materials to modern component materials. Always at the forefront is the need to provide these components on very short deliveries. The machine is designed to provide these components with production schedules from a few hours to a few days.

Today, a fully modern spinning machine consists of numerous controls capable of exerting force on the sheet metal with the greatest precision, and many other refinements. One of these is the electromagnetic clamp, which applies the spinning roller to the metal. It should be noted that the rotational speed of the rollers is variable, thus giving the operator control of the final form of the workpiece. The modern control system provides easy, repetitive operation and simple die changing. There are many controls in the spinning machine, but the primary purpose of these servo-driven units is to control the contact angle between the workpiece and the roller, and the curve progression of the workpiece as it is worked. Additionally, there are the many programmable stopping points, which include both a retract stroke (to allow component removal) and a total sheet-removal stroke advanced by the required preselected amount.
