In order to select a tube bending machine with a minimum ton size, it is best to plan for a bending radius greater than the thickness of the material and to use free bending as much as possible. When the bending radius is large, it is often chosen without affecting the quality of the piece and its future use. The choice of pipe bending machine will not only affect the bending effect of the material, but will also relate to the actual production cost of the equipment, once the wrong choice may increase the cost. So when buying cnc tube bender, you still need to consider a variety of factors. First of all, it is worth noting that every part of the automatic pipe bending machine, in order to meet the processing tasks, the premise of the shortest workbench, the smallest tonnage of the aircraft. At the same time, careful consideration is needed of the material grade and maximum processing thickness and length. If most of the work is low-carbon steel with a thickness of 16 and a maximum length of 3m, then the free bending force does not have to be greater than 50 tons.
Under the same load, the chances of a 10-foot machine workbench and slider deflection increase significantly, which means that shorter machines require fewer gasket adjustments to produce qualified parts, and less gasket adjustments and shorter preparation times. Assuming that the thickest material is 1/4 inch, 10 feet of free bending requires 200 tons, and a pipe bending machine bottom die bend requires at least 600 tons. If most artifacts are 5 feet or less, the tonnage is almost halved, greatly reducing acquisition costs. It can be seen that the length of the part is very important to determine the specifications of the machine.
