The blade of a paper slitter is easily damaged under long-term high-pressure work. Let's take a look at the cause of the blade damage of the paper slitter.
        The damage of the slitter blade is the same as the wear of the slitter blade, which is also a form of failure of the slitter blade. When the cutting machine blade is used under certain cutting conditions, if it cannot withstand strong stress (cutting force or thermal stress), sudden damage may occur, causing the tool to lose its cutting ability in advance. This situation is called cutting. The machine blade is damaged. Damage is relative to wear.
        In a sense, damage can be considered an abnormal wear. There are two types of damage to the blade of the slitter: early and late (breakage after processing to a certain time). There are two types of damage to the blade of the slitter: brittle damage and plastic damage. When cutting hard alloy and ceramic cutting machine blades, under the action of mechanical and thermal shock, brittle damage often occurs. Brittle damage is further divided into: chipping, breaking, peeling, and crack damage.

        The form of blade damage of the slitter is mainly wear and tear. In the modern production system (such as FMS, CIMS, etc.), when the blade of the slitter is abnormally worn or damaged, if it cannot be found and taken measures in time, the workpiece will be scrapped, or even the machine tool will be damaged, causing great losses. Therefore, it is very important to monitor the blade status of the slitter.
