For example, if the board needs to be cut into two finished products with a width of 600mm, the left side cutter needs to be adjusted to a position 600mm away from the center line, and the right side cutter needs to be adjusted to a symmetrical position at the same time. This process relies on manual measurement and positioning, and the single adjustment takes a long time and has low efficiency.
