What is Metal Spinning?

Metal spinning is a cold-forming process where a flat metal disc or tube is rotated at high speed on a lathe while a tool, often called a roller or mandrel, applies pressure to form the metal into a desired shape. The process is analogous to potter’s wheel shaping clay but involves metal instead of clay.

The key components involved in metal spinning are:

• Workpiece: The metal disc or tube to be spun.
• Lathe: The machine that rotates the workpiece at high speeds.

3. Sheet Metal Cutting: A flat sheet of metal is cut slightly larger than the final product. This accounts for material maneuvering and trimming after shaping. Shearing or waterjet cutting are common methods used.

Machine Setup and Shaping:

4. Mounting: The metal sheet is securely clamped onto the mandrel on the metal spinning lathe. A tailstock die (follower rest or live center) applies pressure to the back of the sheet, helping it conform to the mandrel during spinning.
5. Tool Selection and Positioning: The spinning tool is chosen based on the desired shape. A basic roller with a smooth profile works for simple shapes, while forming rollers with specific contours are used for complex shapes. The tool is then mounted on the tool rest of the lathe.
6. Spinning and Shaping: The lathe spins the mandrel and metal sheet together at high speed. The operator skillfully guides the spinning tool along the mandrel, applying controlled pressure to progressively shape the sheet metal. This pressure causes plastic deformation, stretching the outer areas and compressing the inner regions to match the mandrel’s form.
7. Multi-Pass Approach: Skilled metalworkers rarely achieve the final shape in one go. They typically use multiple passes with the spinning tool, focusing on specific sections or progressively refining the shape. This multi-pass approach allows for better control, minimizes imperfections, and ensures even material thickness.

Finishing:

8. Trimming: Once shaping is complete, the excess metal around the edge of the formed piece is trimmed away using shears or a trimming tool.
9. Finishing Touches: The finished part may undergo additional processes like polishing, sanding, or painting depending on the desired outcome. This step improves the aesthetics and functionality of the final product.

Additional Considerations:

• Speed and Lubrication: The spinning process often occurs at high speeds to minimize friction and heat generation. Lubrication is also important, as it reduces friction between the tool and the metal sheet, aiding in shaping and extending tool life.
• Manual vs. CNC Spinning: Metal spinning machines come in both manual and CNC (computer numerical control) varieties. Manual machines rely on the operator’s skill to manipulate the tool and achieve the desired shape. CNC machines use a pre-programmed digital blueprint for precise tool movements, making them suitable for complex shapes and high-volume production.
