1. Safety: The paper cutter is different from other mechanical products. It belongs to the four-level dangerous machine tool with the highest level of danger. Safety is the primary issue in the purchase and use of the paper cutter. Therefore, when choosing a paper cutter, we must focus on its safety and reliability.
        2. Mechanical structure: The earliest mechanical paper cutter uses spring pressure to press the paper, and the sliding paper structure is used to push the paper. The structure is relatively simple, and the commissioning and maintenance are also convenient, but the pressure of the paper is low, and the cutting accuracy is poor. The cutter with double guide rail structure is very troublesome when adjusting the precision, and it is more expensive to replace the guide rail after wear. The adjustment accuracy of the paper cutter with dovetail groove structure is simple and convenient. Once the wear occurs during use, only the plug iron can be replaced. Therefore, when choosing a paper cutter, you should choose a double-rail paper cutter or a dovetail slot cutter according to the actual situation of the product you want to process.
        3. Work efficiency and cutting accuracy: The efficiency and cutting accuracy of the paper cutter is an aspect that printing companies consider more when purchasing paper cutters. For printing, the higher the efficiency of the printing press, the higher the profit. So how to choose the paper cutter to improve the working efficiency of the printing machine is a very important thing.

        4. Comparison of energy consumption: In addition to the above comparison, paper cutters of the same model also have to compare the power consumption of the whole machine, because the size of the motor power is not just a problem of power consumption.
