Spinning Technology

What is metal spinning?

Metal spinning is a technology used at LaserNett to form and shape metal into axially symmetric forms.

Metal spinning is a process by which a metal disc or tube is spun at high speed on a lathe and formed into an axially symmetric form.

Metal spinning is performed in one of two ways; manually or by a CNC lathe. Metal spinning forms range from decorative household goods, cookware, gas cylinders, cups and automotive emission control products. Shapes can be formed from aluminum or stainless steel to high-strength and high-temperature alloys.

The spinning is simple metal fabrication process. The sheet metal you wish to form to is mounted onto the rotating section of the lathe. A pre-sized metal disk is then clamped against the block by a pressure pad, which is attached to the tailstock. The block and workpiece are then rotated together at a high speed. A localized force is then applied to the workpiece to cause it to flow and shape over your formed block. The force is usually applied via various levered tools. Simple workpieces are removed from the block whereas more complex shapes may require a multi-piece block. Extremely complex shapes can be spun over ice forms, which then melt away after spinning. Because the final diameter of the workpiece is always less than the starting diameter the workpiece must thicken, elongated radially, or buckle circumferential.
