The rolling process is a high{{0}}efficiency and high-quality process measure. Now, the effect of rolling is proved by taking the 160mm diameter mirror doctor brand cutting rolling head as an example. After rolling, the surface roughness of the cylinder rod is reduced from Ra3.2-6.3μm before rolling to Ra0.4-0.8μm, the surface hardness of the cylinder rod is increased by about 30 percent , and the surface fatigue strength of the cylinder rod is increased by 25 percent . The service life of the oil cylinder is increased by 2 to 3 times, and the rolling process is about 15 times more efficient than the grinding process. The above data shows that the rolling process is efficient and can greatly improve the surface quality of the cylinder rod.
