When most users choose aCNC bending machine，他们主要考虑材料等级，以及最大的加工长度和厚度，相对容易理解。当然，这是指用户自己处理物品的情况，可以做出精确选择。只有这样，才能降低成本的产出。应该知道弯曲机的选择是否适当，可以直接与成本问题直接相关。

一般来说，它是看用户想要生产的部分类型的部分，并根据确认自己的大量条件选择bending machine，并且没有必要选择不需要的吨。

In addition, in order to select a low tonnage standard, it is possible to select a thickness greater than that of the parts made by itself. In this case, it can be ensured that the machine does not perform load work under certain circumstances, and the service life of the bending machine can be ensured. Of course, if the tonnage is too large, it will affect the degree of production of the part, and if it is slightly larger, it will not affect this.

What the user needs to do is to carefully consider the material grade and the maximum processing thickness and length. If most of the work is low carbon steel with a thickness of 16 gauge and a maximum length of 10 feet, then the free bending force does not need to be greater than 50 tons. However, if you are engaged in a large number of bottomed die forming, perhaps a 150-ton machine tool should be considered. Assuming that the thickest material is 1/4 inch, 10 feet of free bending requires 165 tons, and bottomed die bending (correction bending) requires at least 600 tons. If most parts are 5 feet or shorter, the tonnage is almost halved, which greatly reduces the cost of purchase. The length of the part is very important to determine the specifications of the new machine.

Of course, the selection of thebending machineis mainly based on the user’s own situation, which is inevitable and a direct factor in reducing production costs.

The bending machine can also be used to press the dead edge of the workpiece, first bend the workpiece to 30 degrees, and then use a flat knife to press the workpiece to death, but generally the dead edge completed by the general punch is not organized into the bending machine as much as possible. The role of the dead edge is relatively better.

在安排过程时，通常需要考虑是否容易弯曲，是否可以弯曲。由于弯曲是一个非常重要的过程，弯曲是否好或不直接影响弯曲质量的保证，并且出现多次。产品的质量问题全部由弯曲尺寸造成的不受欢迎，因此在设计过程中应特别注意弯曲问题，这与批量生产期间产品质量的稳定性有关。

In the actual bending process, various problems will be encountered. In many cases, the influence of bending on other processes must be considered. In many cases, specific problems must be analyzed in detail and the appropriate organization process. At the same time, in the case of some special needs, the supplier will also make special bending knives, but if the shape of the knife is more strange or the curvature is larger, it will inevitably affect the rigidity of the tool and shorten the life of the tool.

目前，金属板的发展CNC press brake折弯机也面临许多挑战。The application of CNC system, CAD and CAPP and flexibility are developing rapidly. However, my country’s sheet metal CNC press brake bending machine industry wants to continue to develop and grow. there’s still a long way to go.
