In normal production, it is not difficult to find that the cutting accuracy of paper products is one of the defects caused by the daily quality performance of products. After performing observation and research, it was found that in addition to the improper operation of the paper cutter, there is another reason that the debugging has not been done well. This is mainly because the precision adjustment of the equipment is very patient and meticulous. Only when the calibration is in place can we produce better and more accurate paper products.
