A CNC press brake sheet follower supports the workpiece as it rotates during bending. By synchronizing the support movement with the bending process, it helps reduce sheet sagging, twisting, and deformation caused by the workpiece's weight. This is particularly useful when processing large, long, or thin sheet metal parts that are difficult to support manually.
Improved bending accuracy
A sheet follower provides continuous support as the workpiece changes angle during bending. This helps maintain a stable workpiece position and reduces deformation caused by unsupported sections of the sheet.
The support movement can be synchronized with the bending process through an electrohydraulic servo driven crank linkage or a servo motor drive. Matching the support speed to the sheet's movement helps maintain consistent contact and improves bending repeatability.
The actual bending accuracy also depends on the material, tooling, machine condition, and CNC settings.
Reduced labor requirements
Bending large sheets manually can require three to four operators to hold and support the workpiece throughout the operation. This increases labor requirements and makes the process more dependent on operator coordination.
A sheet follower automatically supports the workpiece as it moves, reducing the need for manual lifting and repositioning. Depending on the workpiece size, weight, and machine configuration, this can reduce the number of operators required for a bending operation.
Higher production efficiency
A CNC controlled sheet follower adjusts its support position and height during bending, reducing the need for repeated manual adjustments.
Automated support also helps maintain consistent workpiece handling between bending cycles. This can reduce interruptions caused by repositioning, unstable sheet movement, or handling errors, particularly in repetitive production.
Adaptability to different tooling configurations
Different punch and die configurations can change the working height and support requirements. A sheet follower can adjust its position and height to suit different tooling arrangements, keeping the support surface aligned with the upper surface of the lower die where required by the machine design.
This adjustment helps accommodate workpieces of different sizes and geometries. The available adjustment range depends on the follower's mechanical structure and control system.
Improved workpiece quality
Uncontrolled sheet movement during bending can cause sagging, twisting, surface scratches, or inconsistent dimensions. A sheet follower supports the workpiece throughout the bending cycle, helping reduce these problems.
More stable support can improve dimensional consistency and protect the surface finish, especially when processing long panels or thin sheets. The final result still depends on material properties, tooling selection, bending parameters, and machine accuracy.
Convenient operation and maintenance
CNC controlled sheet followers automate much of the support movement, reducing the amount of manual coordination required from operators. Once the appropriate parameters have been set, the support can follow the programmed bending sequence.
Maintenance requirements depend on the drive mechanism and overall design. Routine checks should cover the drive system, moving joints, guide components, support surface, and relevant electrical or hydraulic connections. Keeping these components in good condition helps maintain stable operation.
