4.Flexibility:
Due to changes in market demand and diversity, more small quantities, more varieties, complexity of the order is gradually increasing, but because of the intensification of competition in the market, we can not ask customers to make changes in the premise of not increasing the cost of output will need to flexibilisation and high-efficiency equipment, a new generation of modular design, more multi-functional coverage, processing and more reliable control of the system has become the development of the future requirements of the machine.Flexibility is currently a problem in the production of intelligent CNC bending machining centres, is necessary to complete the multi-variety bending processing tasks. At present, to solve the flexible design of CNC bending machine, has become an important industry, to achieve flexible processing CNC bending machine function for the purpose of a new generation of modular design is continuing to influence the development and design of CNC bending machine system.From the workpiece bending processing practice, in order to expand the functional coverage area, to meet the demand for flexible processing designed for the purpose of the CNC system, to meet the different needs of different users in the workpiece bending processing parameters, processing methods, etc.; in the same group of control system support, the CNC system can be based on the input of the production process information to automatically complete the dynamic adjustment of the flow of information, and then organised in an orderly manner of the different processing tasks.
5.Ease of use, consistency, automation:
Intelligent flexible bending centre adopts graphic visual programming, workers only need to input bending data according to the workpiece, the system automatically generates bending instructions, no need to use code programming, ordinary workers can master in 2 hours.Traditional CNC bending centres require workers to master complex programming skills and to memorize the bending sequence of each fold in the bending process, which is difficult and has a high error rate. Intelligent flexible bending centre can achieve automatic positioning of the plate, the system has high positioning accuracy, the consistency of the formed product is higher, and it is more suitable for batch production.Traditional CNC bending centres are not positioned with high precision and can suffer from dimensional errors due to multiple positioning. Intelligent flexible bending centre is reserved with rich interfaces, which is convenient for docking with upstream and downstream production lines. It can be docked with robotic arm to achieve automatic integrated loading and unloading. With self-driven robotic arm and intelligent flexible bending centre with the same control system, synergistic efficiency; replacement of workpieces without maintaining two sets of programs, only need to change the bending centre program, automatic generation of robotic arm program, higher flexibility.
