Differences between CNC press brake and NC press brake

One type of CNC bending machine relies on the program to complete each process; the sheet metal bending machine is a single bending.

What are the differences between CNC bending machine and sheet metal bending machine? The processing technology of CNC bending machine?

　　 Features of CNC bending machine:

　　 1. Direct angle programming, with angle compensation function.

　　2, the grating ruler real-time detection feedback copy correction, full closed loop control, back gauge and slider dead gauge positioning accuracy is ± 0.02mm.

　　3. The upper mold adopts a quick clamping device, and the lower mold adopts a wedge deformation compensation mechanism.

　　4. It has multi-step programming function, which can realize multi-automatic operation, complete the one-time processing of multi-step parts, and improve production efficiency.

　　 5. According to user needs, the imported hydraulic system with stable performance and compact structure can be selected, and the back gauge can be driven by ball screw and timing belt.

　　The full name of sheet metal bending machine is hydraulic sheet metal bending machine. Anhui Yongya believes that its characteristics are:

　　 1. It adopts all-steel welded structure with sufficient strength and rigidity.

　　 2. Hydraulic upper transmission, the cylinders at both ends of the machine tool are placed on the sliding block to directly drive the sliding work.

　　 3. The slider synchronization mechanism adopts a torsion shaft for forced synchronization.

　　4. Using mechanical block structure, stable and reliable.

　　5. The stroke of the slider can be adjusted quickly by motor, fine-tuned manually, and the counter is displayed.

　　6. ​​Wedge-type deflection compensation mechanism to ensure higher bending accuracy.

　　In the bending process of CNC bending machine manufacturers, with the current technology, the biggest problem is how to reduce the preparation time before actual processing, especially when the product needs to be processed repeatedly. For the first processing, in addition to confirming the drawings, it is also necessary to consider the processing molds, the bending sequence of the workpiece, and the program input. However, in the actual processing, these factors must be considered comprehensively, and there must be no omissions, and it takes a lot of time. Long, if next time you encounter the same workpiece and need to repeat processing, you can’t effectively call the last processing programming information, you can only reprogram, repeat the same work, also called “two repetitive operations”, in this case, it is Great waste of time and labor, repeated consumption, resulting in a decline in the processing efficiency of the bending machine.
