CNC Sheet Metal Bending

Product Details: CNC sheet metal bending at Komacut allows for the creation of a wide variety of part geometries without the need for custom tooling. The process utilizes air bending and bottom bending techniques, with air bending being used for its speed and flexibility in producing multiple bend angles with the same die. This method is particularly useful for low to medium volume production, enabling the production of complex shapes, enclosures, brackets, and other parts quickly and with high repeatability. The process is automated, allowing for 24/7 production with minimal personnel, and it can handle materials such as steel, aluminum, and other

metals. Key factors to consider include angle, radius, material, and multiple bends, with angular tolerances of +/- 0.5 degrees and XYZ tolerances of 0.30 mm[1][3][5].
