In order to make the edges of the paper cut by the programmable paper cutting machine smoother, it is necessary to make the blade sharp enough and adjust the sharpening to an appropriate angle. Cutting different paper requires adjusting to different sharpening angles. If cutting softer paper, the blade grinding angle can be adjusted to 16 degrees; If you want to cut cardboard or kraft paper, adjust the angle of the sharpening to 20 degrees; If cutting commonly used printing paper, adjust it to 21 degrees.
