How to choose the knife edge in the paper cutter

The paper cutter is very familiar to the print shop and the graphic shop. It is also the core tool. Whether it is cutting photos or other things, it is inseparable from the paper cutter. Below, let's talk about how to choose the paper cutting knife's edge in the paper cutter.

For the program-controlled paper cutter, we may encounter that the cut paper does not meet the requirements, but the paper cutter knife of the paper cutter and the press bar have good performance, but not all the surfaces are vertical enough. An arc-shaped concave shape is formed in the middle of the cut surface so that the middle portion and the upper and lower portions have a distance difference of 1-5 mm.

When the performance of the program-controlled paper cutter is good, if the cutting surface is curved, it may be due to the improper cutting edge angle of the cutter. In the actual operation process, if the original offset paper should be replaced with coated paper, but the cutter is not replaced, the knife edge angle will not be suitable, so the cut paper size will not be It is suitable. But when we replaced the cutter, the cut paper was normal. At the same time, after measurement, we found that the knife edge angle of these two cutters is only 2 degrees, but the difference in paper size cut out is more obvious, which also shows that in the program-controlled paper cutter, There is a very close relationship between the selection of the knife edge and the quality of the cut.
