Adopted laser leveling machine down instead of mechanical press

Adopted laser leveling machine down to replace the mechanical pressure, laser can make the operation more smoothly under pressure, fast response, more important is that it can achieve overload protection. When the roll gap is plank jacking, laser screwdown will change accordingly roll gap to adjust to changes in the plate thickness; Two roller sticky occurs, especially laser cylinder unloading immediately, to carry on in a timely manner to protect the article reprinted from transmission parts such as laser cutting machine
