Technical Field

[0001] The utility model relates to the technical field of grinding equipment, in particular to a shaft polishing device for engineering machinery. Background Art

[0002] In the field of engineering machinery, the shaft is a key component in various mechanical equipment, and its quality directly affects the overall performance and service life of the mechanical equipment. In some application scenarios, a groove needs to be opened on the shaft, and the inner wall of the groove often needs to be finely polished to ensure its surface is smooth. If the inner wall of the groove is polished manually, it is time-consuming and laborious, and it is difficult to meet the needs of high-efficiency production. For this reason, we propose an engineering machinery shaft polishing device. Utility Model Content
