In recent years, continuous advances in technology have brought a growing number of intelligent rebar processing machines to the market. The CNC rebar cage spiral winding machine and the CNC rebar cage rolling & welding machine are two such new-generation intelligent machines. So what exactly is the difference between them?

CNC Rebar Cage Rolling & Welding Machine

The rolling & welding machine does not require a manually fabricated skeleton. To produce a rebar cage, the operator simply feeds the main bars through the rebar guide pipes and secures them in place, which results in cages of consistent, standardized quality. The machine travels on a rack-and-pinion drive system, ensuring that the spiral spacing of the cage winding remains uniform — which is why it has become essential equipment for major projects. Its purchase cost, however, is relatively high. On the upside, the machine can be recycled and retains a resale value, helping users save on overall costs while also conserving resources at the national level.

CNC Rebar Cage Spiral Winding Machine

The spiral winding machine, also known as the simplified rebar cage rolling & welding machine, differs from the full rolling & welding machine in one obvious way: the skeleton (cage frame) must be pre-fabricated manually and then placed on the machine for the winding process. Its key advantage is speed — a standard cage can be completed in just over ten minutes. In addition, the machine is controlled by a remote control, so it can be operated from a distance. Its traveling carriage also supports reverse winding, which greatly saves workers' time and boosts cage output efficiency — a feature that not every manufacturer can offer. Moreover, the drum of our spiral winding machine adopts a seamless connection design, so it will not jam the drive ring.
