I plan to cut a 50 micron thick aluminum foil into squares with side lengths of 2cm, 5cm, and 10cm.

Due to the manufacturing and fitting accuracy of the disc knives and knives, the shearing part may cause scratches, craters, burrs and other quality defects.

Due to the use and design problems of the surface pressing roller, the take-up shaft and the die, the coiling portion may cause quality defects such as flanging, split layer, and unstable internal stress.

PS: The heat generated by the laser will damage the Al foil edges, so we gave up the laser cutting technology.
