Abstract:In order to explore the influence of ultrasonic rolling process parameters on the surface properties of 12Cr2Ni4 A steel， the effects of spindle speed ， feed rate， machining times and rolling reduction on the surface roughness and surface topography of 12Cr2Ni4A steel were studied. The original surface and the machined surface were measured by the surface roughness meter， and the 12Cr2Ni4A steel surface profile was visualized by using the ultra-depth of field microscope. The results showed that after ultrasonic rolling processing of 12Cr2Ni4 A steel， the machining marks of turning could be significantly reduced ， the surface roughness value of the specimen could be reduced to 0.2 μm， and the surface morphology was greatly improved.
