Product Selection Differences for Metal Spinning or Flow Forming Lathes

Metal spinning and flow forming are metalworking processes used to produce cylindrical components like cones, cylinders, and other symmetrical shapes. Both processes involve shaping a metal disc or tube over a rotating mandrel to form the desired shape. Here are the key differences between metal spinning and flow forming lathes:

1. Process and Control:

   • Metal spinning involves manually shaping the metal using hand tools, while flow forming typically uses hydraulic or numerical control (CNC) machines for more automated and precise shaping.

2. Material Thickness:

   • Metal spinning works well with thinner materials, while flow forming is typically used for thicker materials due to its ability to exert higher forces during the shaping process.

3. Complexity of Shapes:

   • Metal spinning is more suitable for simpler, conical shapes, while flow forming can handle more complex shapes and geometries with higher precision.

4. Tooling and Equipment:

   • Metal spinning setups are simpler and require less complex tooling compared to flow forming, which requires specialized flow forming machines and tooling.

5. Cost and Production Volume:

   • Metal spinning can be more cost-effective for smaller production runs or prototypes due to lower setup costs, while flow forming may be more efficient for larger production volumes.

6. Surface Finish:

   • Flow forming typically produces parts with a superior surface finish and higher dimensional accuracy compared to metal spinning.

7. Tolerance and Consistency:

   • Flow forming generally offers tighter tolerance control and more consistent results compared to metal spinning, making it ideal for high-precision applications.

When selecting between metal spinning and flow forming lathes, consider factors such as your production volume, desired shapes, material thickness, surface finish requirements, and overall budget to choose the most suitable option for your specific application.
