Metal Spinning

As a Manufacturer in China,we make Custom-made Metal spinning parts as above picture shows.

What is Metal Spinning?

Metal spinning, also known as spin forming, is a metalworking technique utilized to transform a flat circular blank or disc-shaped workpiece into round shapes with axial symmetry. This process involves applying lateral force through a roller against the surface of the disc blank, while a high-speed spinning mandrel provides support and imparts the desired shape.

Unlike traditional methods that involve material removal, metal spinning enables the deformation of a circular metal sheet into diverse shapes. As the disc blank is shaped around the mandrel, it undergoes both tensile and compressive forces. The thickness of the original metal sheet may be intentionally reduced, depending on the spinning technique employed. Careful control of this reduction ensures the final product adheres to the specified requirements.

Metal spinning, an ancient technique that blends artistry and scientific principles, dates back to the era of the Egyptians and has undergone significant advancements over the centuries. Originally a manual process, it has now evolved into a sophisticated manufacturing method incorporating computer numeric control (CNC) technology.

Despite these advancements, manual metal spinning remains highly valuable in the production of precise and top-quality finished products. Mastery of this technique requires extensive apprenticeship and a distinct set of skills, emphasizing the artistic nature involved.

With its roots tracing back to ancient Egyptian pottery, metal spinning was inspired by the use of manually operated potter’s wheels as early as 3000 BC. Initially utilized for shaping wood and clay, metal spinning expanded to include the creation of circular iron shields by 25 BC.

During the Middle Ages, metal spinning gained prominence as a means to craft various items such as vases, tea kettles, and trophies. These objects were meticulously fashioned using wood spinning lathes with rotational drives, often powered manually by assistants. This historical context further highlights the enduring relevance of the metal spinning technique.

Metal Spinning Process

It’s a kind of process of Deep drawing.Fixed the flat blank or pre-formed blank to the rotating core die, applied pressure on the blank with a rotary wheel, and the rotary wheel was fed in axially at the same time. After one or more processing, various thin-walled hollow rotary products were obtained (see figure). It can be made of copper, iron, aluminium, stainless steel, titanium alloy and other plasticity materials.

When spinning, the contact area between the wheel and the blank is very small, the processing materials only have plastic deformation locally, and the resistance to deformation is small. Large-scale products can be processed with small-tonnage equipment. It is an effective method to manufacture hollow cones, cylindrical parts, hemispheres and thin-walled pipes and other precision products. Spinning products have high precision, good mechanical properties and wide size range. Spinning tools and dies are simple and easy to replace, and the cost of production is lower than that of other methods in manufacturing some products. The main shortcomings are long production time, low yield and limited varieties. It is suitable for the production of small batch, multi-variety products.
The new general spinning machine and the powerful spinning machine are driven by hydraulic pressure, and equipped with hydraulic profiling and numerical control system.
Small and medium spinning machine tools are mostly horizontal and large spinning machine tools are mostly vertical. Spinning machine tools require good stiffness, high power, high accuracy and good versatility. At present, the largest spinning machine can spin parts with a diameter of 6 meters, and the spinning wheel pressure is up to hundreds of tons.
