How to improve the bending level of CNC bending machine in bending process?

The CNC system adopts a new generation of modular design, with wider functional coverage and stronger reliability, which can meet the needs of different users. The same group control system can automatically adjust the information flow dynamically according to different production processes, so as to play the function of the group control system.

Multi axis linkage machining: after the parts are clamped on a CNC machine tool, automatic tool change, spindle head rotation, worktable rotation and other operations can be carried out to complete multi process and multi surface composite processing, which not only has high smoothness, but also greatly improves efficiency. During cold rolling, recrystallization occurs to form new grains, and the grains extend in the rolling direction. During the bending process of cold rolled metal materials, it is found that when the bending direction is perpendicular to the metal grain extension direction or there is an angle, the bending radius can be appropriately reduced according to the product needs; when the bending direction is consistent with the metal grain extension direction, the bending radius should be greater than the minimum bending radius that the metal can bear, otherwise cracks will appear. The analysis of Wuxi Shenchong shows that the cold rolling makes the strength of grains increase and the ductility decrease in the rolling direction. Therefore, the bending process can be adjusted according to the influence of grain extension direction and material properties on bending angle, bending radius, bending allowance and bending coefficient. The requirement of bending accuracy is a factor that needs to be considered carefully. It is this factor that determines whether a CNC bending machine or a manual bending machine should be considered. If the bending accuracy is ± 1 ° and can not be changed, we must focus on the CNC folding machine.

The repeat precision of the slide block of the NC bending machine is ± 0.0004 inch. This precision and good die must be used for the accurate forming angle. The repeat precision of the slide block of the hand controlled bending machine is ± 0.002 inch, and the deviation of ± 2 ~ 3 ° is generally produced under the condition of using suitable die. In addition, the CNC bending machine is ready for rapid tooling, which is an indisputable reason to consider when many small batch parts need to be bent.
