High-speed slitting machines are currently used very frequently in industry. Let's take a look at the main features and defects of high-speed slitting machines.

        The main feature of the high-speed cutting machine is that the magnetic powder clutch is installed as a resistance. After system control, a DC voltage is output to control the resistance generated by the magnetic powder clutch. The main advantage is that it is a passive installation that can control less tension. The main drawback is that the speed cannot be high, and high-speed friction of magnetic powder is easily formed during high-speed operation, which generates high temperature, which causes the magnetic powder clutch to generate heat and shorten its life. Use a knife to cut the roll of a certain width longitudinally and cut it into several narrower rolls for installation.
