What is Metal Spinning?

Metal spinning can be divided into conventional spinning and power spinning.

• Conventional spinning only changes the shape of the blank without altering its thickness.

• Power spinning changes both the thickness and shape of the blank. It requires higher forming forces, and the spinning machine used is generally more complex in structure.

Power spinning can be further classified into forward spinning and reverse spinning based on the relative movement of the roller and the metal flow:

• Forward spinning occurs when the roller moves in the same direction as the metal flow.

• Reverse spinning occurs when the roller moves opposite to the metal flow. For the same material, reverse spinning requires higher forming forces.

The choice of spinning method depends on the part’s shape and specific process requirements.
