In order to make the edge of the paper cut by the program-controlled paper cutter more flat, the blade edge of the blade must be sharp enough, and the sharpening must be adjusted to an appropriate angle. Cut different papers and adjust to different sharpening angles. If you are cutting soft paper, you can adjust the blade's sharpening angle to 16 degrees; if you want to cut cardboard or kraft paper, you can adjust the sharpening angle to 20 degrees; Just turn to 21 degrees.

         In order to ensure the quality of the cutting, maintenance work is also required. Depending on the season, you can add the appropriate motor oil. The hydraulic pressure should be appropriate. If the pressure is too large, the sealing ring will burst, and if the pressure is too small, the blade will be weak when cutting. You can use talcum powder or paraffin wax on the cutting platform and knife edge to reduce friction resistance.
