Function Description
The ESA S840R is used to control multi-axis CNC press brakes. It manages ram synchronization, X/R backgauge movement, Z1/Z2 positioning, and CNC crowning compensation.
Compared with a 4+1 axis system, the S840R provides more flexible backgauge positioning, making it more suitable for parts with different bending widths, complex positioning requirements, and higher production efficiency.
Applicable Machine
CNC Press Brake, Hydraulic Press Brake, Electric Press Brake, Hybrid Press Brake
