During the cutting process of the rolling mill, due to the high hardness of the cast iron rolling mill itself, the high precision requirements of the rolling mill itself, and the complex structure of the rolling mill, the cutting process of the rolling mill has higher technical difficulties compared to normal accessory processing. In order to improve the efficiency of cutting processing, ensure the accuracy of rolling mill processing, and solve the technical problems of rolling mill cutting processing, it is one of the key links in rolling mill production. Based on the technical and operational difficulties of rolling mill processing, after a long period of exploration, from theoretical analysis to practical operation, we have summarized some rolling mill cutting technical parameters, which have good feasibility in improving rolling mill cutting efficiency, ensuring rolling mill processing quality, and reducing processing costs. Note: The specifications and cutting parameters of different materials of rolling rolls, selected CBN blades may vary depending on the actual situation.
