Metal work surface after rolling, surface enhanced strength and yield point increase work performance, fatigue resistance, abrasion resistance and corrosion resistance are improved significantly. After passing rolling, the hardness increase 15~30%, and wear-resistant 15%.
Rolling process can improve surface roughness from Ra6.3 to Ra2.4~Ra0.2. And has high production efficiency, some parts can be completed in a few minutes or a few seconds.
Rolling process to solve the key problem of some process is not easy to achieve. For example the processing of extra large cylinder. It also applies to the small hole finishing or finishing of certain special materials.
Rolling process using a wide range of major, medium and small factories to use. Both in terms of quality, productivity, in terms of production cost, rolling is a superior method. In some ways, it completely instead of grinding, lapping, honing and finishing.
