摘要
为了探究超声滚压加工参数对12Cr2Ni4A钢表面性能的影响,分析主轴转速、轴向进给量、加工次数及压下量对12Cr2Ni4A钢表面粗糙度和表面形貌的影响规律。通过表面粗糙度测量仪对原始表面及加工后的表面进行测定,并选用超景三维深显微镜对12Cr2Ni4A钢表面形貌进行可视化分析。结果表明,12Cr2Ni4A钢在经过超声滚压加工后,能显著降低车削的加工痕迹,试件的表面粗糙度降低至0.2μm,表面形貌得到极大改善。
In order to explore the influence of ultrasonic rolling process parameters on the surface properties of 12 Cr2 Ni4 A steel,the effects of spindle speed,feed rate,machining times and rolling reduction on the surface roughness and surface topography of 12 Cr2 Ni4 A steel were studied.The original surface and the machined surface were measured by the surface roughness meter,and the 12 Cr2 Ni4 A steel surface profile was visualized by using the ultra-depth of field microscope.The results showed that after ultrasonic rolling processing of 12 Cr2 Ni4 A steel,the machining marks of turning could be significantly reduced,the surface roughness value of the specimen could be reduced to 0.2μm,and the surface morphology was greatly improved.
