Bender Roll machines form metal into cone, curved, or cylinder shapes. They are also called roller machines or rounders. There are CNC roll benders, manual roll benders and hydraulic roll benders. The bender rolls work by rotating the workpiece while bending to form the desired shape. There are 2-Roll, 3-Roll and 4-roll bending machines. The 2-Roll bending machines are best used for smaller materials as well as thin materials. They are also good for high volume shops that need materials formed as fast and as uniform as possible. The 3-Roll bending machines are very similar to the 4-Roll machine except they typically do not come with a CNC control. The 3-Roll can bend thin materials as well as some materials that are around four inches thick.
Most machinists agree that the 3-Roll machine is an older technology and prefer a 4-Roll. A 4-Roll machine is the most sought-after bender rolling machine due to its advanced controls and accuracy. They can handle thicker materials but also handle them in a shorter amount of time compared to the 3-Roll. This is due to the machines having the capability to have CNC controls built into them. Using CNC controls with a 4-Roll bending machine will improve the productivity in your shop.
