Rolling of variable-diameter wire rod
The booming electric bike market requires new manufacturing processes for bicycle spokes. Aachener Maschinenbau GmbH (AMBA) developed the new spoke-blank reducing machine “DD-350”. Rolling provides high degree of flexibility in the manufacture of spoke blanks.
The new machine produces double thick end spokes with a diameter of only about 1.5mm in the middle. © Aachener Maschinenbau
