Analysis of Causes of Cutting Edge Breaking of Paper Cutter

 For printers, a paper cutter is a necessary machine. The paper cutter is used to cut the paper before and after printing. The paper cutter is easy to operate and has no special requirements on the environment. As long as the power is supplied, it can work normally. After the paper cutter is used for a long time, there will be some problems, such as the paper cutter does not move, abnormal noise, and the pusher does not move.

Some users reported to us that the newly installed paper cutter cuts a knife, and the blade has a problem of chipping. Below, I will give you a brief analysis of the cause of the  paper cutter's cutting edge? The selection of the blade sharpening angle, the quality of the sharpening, and the sharpening clearance time of the blade affect the flatness and smoothness of the paper cutting edge. Generally, the angle of the blade is 19 °. To increase the angle of the blade, if you want to improve the sharpening quality of the blade, make sure that the coolant is sufficient during the sharpening to avoid the edge annealing. Before cutting, you can first polish the blade with a fine stone and apply soap and paraffin on the blade. This can not only improve the sharpness and smoothness of the cutting edge, but also extend the service life of the cutting edge, and the quality of the finished product is better.

The reason for the chipping in actual operation is that the operator shortens the sharpening time, and the coolant is insufficient, which causes the edge to anneal and the width to be narrowed. The nut must be adjusted during installation to make the blade cut into the pad Blades, if the nut is not adjusted properly, and the cut is too deep, it will cause chipping.
