In the metal spinning process, a metal sheet is flattened into a disc and spun around a mandrel to create symmetrical, spherical shapes. Metal spinning creates shapes like hemispheres, cones, dishes, domes, cylinders, and flanges. Stainless steel bowls, satellite dishes, and brass instruments, including trumpets, tubas, cornets, and gas cylinders, are some products made by metal spinning. Read More…
Metal SpinnersMetal spinners are metalworking tools used to create axially symmetric, round metal shapes. A metal spinning system, in its most basic form, can be as simple as a lathe, a mandrel and some spinning tools.

The following are some methods that metal spinners may employ in their procedures.
Computerized Numerical Control (CNC)
CNC metal spinning uses a lathe to automate and control the metal spinning procedure. Manual spinning and CNC metal spinning processes start similarly. First, the operator sets the workpiece on the CNC lathe drive and secures it with a pressure pad. Next, the settings for the forming process are programmed into the CNC machine. Finally, the workpiece is rotated and pressed against the mold when the lathe turns on. Like manual lathes, the CNC lathe's spinning force bends the metal piece into the mold's shape. CNC metal spinning is popular for its affordability, superior tensile strength, outstanding finishes, and refined grain structures.
Playback Numerical Control (PNC)
With PNC metal spinning, the operator manually shapes the workpiece using a joystick. Eventually, the planned piece is created. The machine then remembers and repeats the adjustments, copying the operator's movements. PNC metal spinning makes high-volume production more effective. In the replay mode, the lathe copies the original part precisely by repeating the forming process as many times as necessary. Finally, the operator mounts the blank on the lathe, initiating the playback cycle.
Hand Metal Spinning
The metal to be spun is placed on holders using a combination of talent and engineering. Then, a motor rotates the metal as a skilled individual molds it into the desired result.
The Metal Spinning Design Process
What is the object’s function?
Knowing the purpose of the workpiece will inform every step of the design process, and ensure final results genuinely meet the customer’s needs.
What material will work best for this metal spinning project?
The material used influences the way metal is spun. Designs could vary from being a millimeter thin or an inch thick. Manufacturers and clients should work together to choose the best material for the project.
Carefully consider the diameters.
It is common for metal-spun objects to be rolled into tubes. Metal spun objects have different thicknesses. Large corner radii will wear down the material slower than small corner radii. Larger corners are stronger and more cost-effective than tight corner radii.
Think About the Dimensions.
It’s crucial to plan out the required dimensions. Saving even a bit of material can result in huge financial savings for the project.
A metal-spun product doesn’t require a constant thickness throughout. However, the designer must specify an acceptable deviation from the true value.
Challenges faced by Metal Spinning Manufacturers
Shape and Size
In conventional or modern spinning processes, size and shape variaitons are limited. This makes it simpler to produce axially symmetrical and concentric forms. Shapes with dished heads, stepped edges, parabolas, funnels, cones, and hemispheres are easier to spin. Additionally, the diameter of the manufactured components is constrained. Using metal spinning to create irregular shapes is a nightmare.
Due to production constraints, rollers and spoons are popular tools when manufacturing metal spinning goods. Manufacturers must create unique tool components for bespoke productions to meet the necessary application requirements. This can entail creating a new mandrel. It would be pointless financially to develop all of this machinery and equipment to create a small number of products. It’s more cost effective to create large quantities of products for customized productions.
Errors are a part of every forming process, including the process of spinning metal. When a dent or crack develops during this process, it cannot be repaired. Repairing tiny flaws or imperfections can be costly. Additionally, before beginning the spinning process, a hardened metals must be subjected to heat treatment.
