Industrial circular knives’ high requirements for processing accuracy

Industrial circular knives are the most important part of the slitting machine, and their processing precision is extremely high. For the flat surface, you need to use the ultra-fine ice grinding machine, which is ground by a special grinding method and undergoes strict quality control to ensure that the thickness and flatness of all finished products are within 0.003mm (max).
