Aluminium Spinning tools

Brass Metal Spinning Brass is most commonly used for decorative metal applications. It is a highly formable metal receptive to many different finishing.
Stainless Steel Metal Spinning Stainless Steel has many special metal spinning applications. Popular for its permanence, strength, and non-corrosive attributes. It is commonly used on exposed exterior applications.
Copper Metal Spinning Copper is very popular within the lighting and decorating industries, prized for its heat resistant qualities and resilience in harsh climates.
Our metal spinning talent and expertise is among the best in the industry, allowing us to produce high quality custom specialty components.

Aluminum Metal Spinning We specialize in spinning Aluminum of various sizes and alloys. A highly polishable metal commonly used in industrial and commercial lighting, we carry a large stock of size and alloy combinations ready for prototype development.
Steel Metal Spinning Steel is a very commonly spun metal. It is very workable with a wide range of Industrial metal spinning applications. Steel components are renowned for their durability and strength.

Objects can be built using one piece of material to produce parts without seams. Without seams, a part can withstand higher internal or external pressure exerted on it. For example: scuba tanks, co2 cartridges, and oxyacetylene tanks

Other methods of forming round metal parts include hydroforming, stamping and or . and generally have a higher fixed cost, but a lower variable cost than metal spinning. Forging or casting have a comparable fixed cost, but generally a higher variable cost. As machinery for commercial applications has improved, parts are being spun with thicker materials in excess of 1" thick steel. Conventional spinning also wastes a considerably smaller amount of material than other methods.

Forming parameters and part geometry can be altered quickly, at less cost than traditional metal forming techniques. Tooling and production costs are also comparatively low. Spin forming is easily automated and an effective production method for prototypes as well as high production runs.

Several operations can be performed in one set-up. Work pieces may have re-entrant profiles and the profile in relation to the center line virtually unrestricted.

ADVANTAGE

The mandrel does not incur excessive forces, as found in other metalworking processes, so it can be made from wood, plastic, or ice. For hard materials or high volume use, the mandrel is usually made of metal

Cutting of the metal is done by hand held cutters, often foot long hollow bars with tool steel shaped/sharpened files attached. In CNC applications, traditional carbide or tool steel cut-off tools are used.

Commercially, rollers mounted on the end of levers are generally used to form the material down to the mandrel in both hand spinning and CNC metal spinning. Rollers vary in diameter and thickness depending the intended use. The wider the roller the smoother the surface of the spinning; the thinner rollers can be used to form smaller radii.

Some metal spinning tools are allowed to spin on bearings during the forming process. This reduces and heating of the tool, extending tool life and improving surface finish. Rotating tools may also be coated with of to prolong tool life. Rotating tools are commonly used during CNC metal spinning operations.

The basic hand metal spinning tool is called a spoon, though many other tools (be they commercially produced, , or ) can be used to effect varied results. Spinning tools can be made of hardened steel for using with aluminium or solid brass for spinning stainless steel or mild steel.

"Hot Spinning". This process involves spinning a piece of metal on a lathe and with high heat from a torch the metal is heated. Once heated, the metal is then shaped as the tool on the lathe presses against the heated surface forcing it to distort as it spins. Parts can then be shaped or necked down to a smaller diameter with little force exerted, providing a seamless shoulder.

A more involved process, known as reducing or necking, allows a spun workpiece to include reentrant geometries. If surface finish and form are not critical, then the workpiece is "spun on air"; no mandrel is used. If the finish or form are critical then an eccentrically mounted mandrel is used.

The spinning process is fairly simple. A mandrel, also known as a form, is mounted in the drive section of a lathe. A pre-sized metal disk is then clamped against the mandrel by a pressure pad, which is attached to the . The mandrel and workpiece are then rotated together at high speeds. A localized force is then applied to the workpiece to cause it to flow over the mandrel. The force is usually applied via various levered tools. Simple workpieces are just removed from the mandrel, but more complex shapes may require a multi-piece mandrel. 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 circumferentially.
