CNC Hydraulic Press Brake's Role in the Production Line
In a sheet metal production line, the CNC Hydraulic Press Brake operates after laser cutting and before punching processes. First, the Laser Cutting Machine performs precise cutting of metal sheets. Next, the CNC Hydraulic Press Brake bends the cut sheets into the required angles and structural shapes. After bending, the workpiece can proceed to the CNC Servo Press for punching or forming operations. This step transforms flat metal sheets into functional structural components.
