Processing technology and principle of aluminum alloy Cylinder Barrel
 
During the rolling process of cylinder pipes, residual compressive stress is imparted to the surface, aiding in the closure of minor surface cracks and impeding the propagation of corrosion. This enhances the surface's corrosion resistance, which can slow down the progression of fatigue cracks or expansions, thereby improving the fatigue strength of the cylinder tube. Rolling forming creates a cold hardened layer on the surface, which reduces the elastic-plastic deformation of the grinding contact area, thereby enhancing the wear resistance of the cylinder barrel wall and preventing burns caused by grinding. Following rolling, the surface roughness value is reduced and can increase naturally over time.
Rolling technology is a chip-free machining process that utilizes the plastic deformation of metals at room temperature to flatten surface micro roughness, aiming to alter the surface structure, mechanical properties, shape, and size. Therefore, this method serves both precision machining and strengthening purposes, and grinding is not applicable. Regardless of the processing method used, the parts surface always exhibits small uneven marks resulting in a pattern of alternating peaks and valleys.

Rolling processing principle: It involves pressure finishing of metals' cold plastic characteristics at room temperature. Rolling tools are employed to apply pressure on the workpiece surface, causing the metal to plastically flow and fill the original low-lying grooves, thereby reducing surface roughness. Rolling induces plastic deformation of the metal surface, leading to thinning, cold hardening, and grain refinement, forming dense fibers and residual stress layers. This enhances hardness and strength, thereby improving the workpiece's surface wear resistance, corrosion resistance, and consistency. Rolling is a processing method used to cut plastics.
