Tube bending machines are specialized tools used to shape and bend metal tubes into various angles and curves. They are commonly used in industries such as automotive, aerospace, and construction, where precise tube shapes are essential for structural integrity and functionality. These machines can handle different materials, including steel, aluminum, and copper, and can produce both simple and complex bends. There are several types of tube bending machines, including mandrel benders, rotary draw benders, and compression benders. Each type operates differently, allowing for a range of bending techniques to meet specific project requirements. The choice of machine often depends on the desired bend radius, tube diameter, and material type.
