What is a metal spinning process?

Metal spinning, also known as spin forming or spinning or metal turning most commonly, is a metalworking process by which a disc or tube of metal is rotated at high speed and formed into an axially symmetric part. Spinning can be performed by hand or by a CNC lathe.

What are the two types of metal spinning operations?

The Spinning process is classified in two types i.e., hot-spinning and cold-spinning, depending upon whether the blank or work piece has been heated before spinning or not. (i) Hot Spinning: In hot spinning, the metal blank is heated to forging temperature and then forming it into the desired shape.

What is a metal spinning machine?

Metal spinning machines are used in metal spinning (spin forming, flow forming), a process by which a metallic disk or tube is rotated at high speeds and formed into an axially symmetric part.

Is metal spinning cheap?

Spinning metal is an inexpensive alternative to the stamping process, with a quicker processing time. Other advantages are very low tooling compared to stamping, as well as very short setup and changeover times. The process is also eco-friendly with less waste being produced.

What do you call the process of spinning metal?

The process of metal spinning – also commonly known as “metal turning” or “spin forming” refers to the fundamental fabrication process where a flat metal disc, the blank, is fixed in a spinning lathe to form a hollow part with a circular cross-section.

How is metal spun in a spinning wheel?

PROCESS OF METAL SPINNING  Spinning tools or spinning rollers are forced against the rotating blank either by hand or by auxiliary power or both.  Employing a series of axial and radial (swivel) strokes, the blank is spun onto the mandrel causing the metal to flow to the shape of the desired part.

What can you do with a metal spinning machine?

Our automated metal spinning machines can turn out complex finished pieces from the blank disc in minutes. Metal spinning is best applied to turn out symmetrical parts with a circular cross-section, but these may later be cut for reassembly in a variety of shapes to create a vast range of new products.

What happens to the grain as metal spins?

As the blank spins, a roller tool forms around it. Usually, as the blank is pressed against a mandrel, the grain structure is compressed, producing a smooth surface that always doesn’t require any other form of secondary finishing. The methods of metal spinning can vary depending on the complexity of the part that is being processed.
