CZU Sigma Interchangeable Roll Forming Machine

C-Z quick interchangeable machine adopts a special structure.

Quick C to Z interchange: The rollers for C & Z are changed very quickly without dismantle any parts, The forming tooling is simply unclamped (two bolts), rotated through 180 degree, and re-tightened. No tooling or spacers are removed or changed. Quick, Easy, Simple.

Size change: The form tooling is unclamped, slid into the correct position by PLC control. No special tools, no spacer changed. Infinite sizes are possible.

Only input data in touch screen can adjust any size automatically, by motor driving stations moving accurately on linear guiderail with encoder.

Our C&Z machine technology follows New Zealand Hayes, now become a part of Bradbury group USA, Bradbury has factory in Shanghai China, they are making C&Z machine using Hayes technology. Hayes has world best technology for C&Z purline machine.
