  1. According to the angle error of the two ends of the folded plate of the press brake, use the hexagonal tube on the press brake to disassemble one end for unilateral adjustment. The Y-axis handwheel rotates a circle of 0.10mm, and adjusts to the appropriate state according to the magnitude of the angle error. Then, finally connect the loose end of the hexagonal tube and it can be used normally.
  2. Check whether there is any deviation in the free state on both sides of the press brake (the two sides of the normal range are allowed to be 0.20-0.30mm). If the deviation value is not within the range, you can use the unilateral eccentric sleeve to adjust appropriately until the two sides are adjusted to the allowable range.
