Tonnage Requirements for Different CNC Press Brake Jobs

Tonnage refers to the amount of force a press brake applies to bend metal. This force is measured in tons and plays a big role in choosing the right machine and tool setup. If the tonnage is too low, the metal won’t bend properly. If it’s too high, it can damage the machine or the material. In terms of a CNC press brake Dubai, knowing how to match tonnage with the job helps avoid mistakes and keeps production running smoothly. What Affects Tonnage Needs: Several things affect how much tonnage is needed for a job. The thickness and type of metal are the main factors. Thicker metals need more force, while softer metals like aluminum need less. The width of the metal being bent also matters. A longer bend will need more tonnage than a shorter one, even if the metal is the same. Material Type and Thickness: Each metal behaves differently under pressure. Steel, for example, is harder and needs more force to bend than aluminum or copper. If you are working with stainless steel that is 5mm thick, it will need more tonnage than the same thickness of mild steel. Lighter materials bend easier, so knowing what type of metal you are working with is the first step in figuring out the right tonnage. Bend Length and V-Die Size: The length of the bend plays a direct role in how much tonnage is needed. A longer bend spreads the force over a wider area, which increases the tonnage. Also, the size of the V-die, the lower tool that supports the metal, affects tonnage. A smaller V-die creates a tighter bend but needs more pressure. A larger V-die spreads the load and reduces tonnage, but might not give the shape you need. Avoiding Machine Stress: Using the correct tonnage also helps protect the machine. Press brakes are built to handle a certain load. Going over that limit can damage parts or shorten the machine’s life. Using just enough tonnage for the job keeps things safe and avoids extra repair costs. Understanding how tonnage works in CNC press brake jobs is key to getting the best results. By knowing your material, bend size, and tool setup, you can match the right force to the task. In modern shops across Dubai and beyond, this knowledge helps keep bending operations smooth, safe, and accurate.
