Rolling is a small non-metal cutting one of the processing technology with high productivity, savings in raw materials and so on, and you can use the lathe, only supported by the necessary tools, suitable for small batch production. Rolling process is very simple processing mechanism. When using a high surface hardness, roughness smaller ball rolling surface of the workpiece to be machined, by the strength of its local compression. When the compressive stress is greater than the material fatigue limit, Roll forming machine that the surface will produce plastic deformation of the workpiece surface so as to achieve the purpose of processing. When the rolling surface of the workpiece being squeezed, its metal surface is compacted, its molecules are more  closely and orderly, and some minor defects such as pores, slag folder, uneven texture can be improved or eliminated, so that mechanical properties, such as fatigue strength, yield strength, surface hardness can be increased. Practice shows that after the material upon rolling, the surface forming machine hardness generally increases by about HV40, is rolling surface roughness The surface roughness by rolling and rolling with the rolling surface hardness and surface roughness, and when be processed surface hardness HRC30 lower than the ball around, the surface to be machined or even get the same with the rolling surface roughness, rolling process is not processing the shortcomings of high hardness material or brittle material.
