The structure of the press brake crowning compensation  table can promise the bending precision for angle and strightness when bending the workpiece.

press brake crowning compensation is a technique used in metalworking to account for deflections in the bed or beam of a press brake machine. Press brakes are used for bending and forming sheet metal or other materials, and they consist of an upper beam and a lower bed. Over time, heavy use and the sheer force involved in bending can lead to slight deformations in the machine's structure. 
Crowning compensation is employed to counteract any deflections, ensuring that the bending process results in accurate and uniform bends across the entire length of the workpiece. Without crowning compensation, the material might not be bent evenly, leading to inconsistencies in the final product.

Crowning compensation is particularly important in applications where precision bending is critical, such as in the production of components for industries like aerospace, automotive, and electronics. It helps maintain the quality and accuracy of bent parts, contributing to the overall efficiency and reliability of the manufacturing process.
