Coal mine support systems are crucial for maintaining roadway access and working face stability, which is of great significance to coal mine construction and production. Among these systems, suspended support equipment is an important component. Suspended support equipment consists of a support column and a hydraulic system. During the processing of the support column, a rolling process is required. Rolling is a pressure finishing process that utilizes the cold plasticity of metal at room temperature. A rolling tool applies pressure to the surface of the workpiece, causing the surface metal to plastically flow and fill the original residual low-recessed valleys, thereby reducing the surface roughness of the workpiece.

[0003] In existing technologies, the main body for the rolling process is the rolling cutter. After processing with the rolling cutter, there will still be fine traces on the surface of the main body of the suspension support, the surface roughness will still be high, and the rolling effect will not be obvious. Summary of the Invention
