Choosing a CNC Profile Bending Machines (also called angle roller)may seem difficult but it really breaks down into a few simple steps. First, determine the maximum size and type of material you will be rolling. Next determine the types of profiles (angles, flats, tubes, etc.) that you will be forming. Lastly determine if you will be rolling material into one simple radius or if you will have or need the ability to have, the capability of forming variable radii.
1#: Yield strength
Regarding the yield strength of the angle iron roller, BIT machines are uniformly calculated based on the yield value of Q235 and have a yield strength of between 36,000 and 38,000 pounds per square inch (PSI). If you have special requirements, please indicate the yield strength of the metal material in the inquiry. The yield value of Q235: refers to the yield value of this material, around 235MPa.
2#: Correctly sized
Whether operators are bending angle iron, tool choice is critical. The tools need to fit the profile yet not be so tight as to negatively affect workpiece shrinkage and growth. A tool that’s too tight can cause localized distortion and, at worst, actually gouge the material surface.
When operators need to bend an open profile like an angle, they have fewer distortion-mitigating tools at their disposal. Beyond tool choice and fit-up, angle iron roller must choose a correctly sized machine, one with sufficient forming tonnage and adequate grip lengths—enough to provide the needed leverage to reduce distortion, but not so long that they will require an excessively long sacrificial straight section, the long sacrificial flat section becomes expensive scrap, reducing the roll shop’s competitiveness.
3#: Different bending capacities
The types of metal a profile bending machine can process largely depend on its bending capacity, we use the section modulus to evaluate the capabilities of the angle iron roller.
Capacity is one of the most notable differences between these profile bending machines, each angle roll has a section modulus rating. Make a list of the materials and the size of the metal profile you work with on a regular basis and consult an expert to figure out what type of profile bending machine is best for you. When determining which angle roll machine is best suited for the task one has at hand, it is important to research what each profile bending machine is designed to do and to understand the materials that one will be working with.
We provided detailed information about the section bending machines, such as capacity and yield.
4#: Unbend end flat
PBH Series profile bending machine has the independent motion of the two lower rollers allowing the operator to minimize the sacrificial unbent flat sections on the workpiece. Beyond this, operators can fine-tune the roll position to minimize the unbent flat even further.
Again, typically a roll shop that bends a small workpiece on a large profile bending machine (section bending machine, angle roll machine) must factor in a long flat section, which increases material costs. Due to the advantages of its structure and working principle, the Double-Pinch Profile Bending Machine solves this problem well.

Compare the information about how much force an angle iron roller can produce and what kind of metals (sheet, roll, etc.) it is designed to handle, and compare this to your site’s mill certificates or other relevant information to see which profile bending machine best fits your needs.
Below we also provide the processing capabilities of the PBH Profile Bending Machine for your reference.
