金属镜面是指表面粗糙度R_a=0.012～0.006(13～14)的金属零件表面,这时能象镜子一样,照出人像或物像。这种表面在某些零件上是必需的,例如,在零件的运动接触面上用来降低摩擦力,在要电镀的表面上用来加强附着性。金属镜面加工的传统方法,是要经过切削、粗磨削、精磨削、研磨或抛光等多道工序,工作量大、效率低、成本高,常常需要熟练的技术工人,且加工出的镜面难免有磨粒造成的条痕或点痕等微小缺陷存在。为此,近年来 Metal mirror refers to the surface roughness of R_a = 0.012 ~ 0.006 (13 ~ 14) metal parts surface, then like a mirror, like a portrait or portrait. Such surfaces are necessary on certain parts, for example, to reduce friction on the moving contact surfaces of parts and to enhance adhesion on the surfaces to be plated. The traditional method of metal mirror processing is to go through many processes such as cutting, rough grinding, fine grinding, grinding or polishing, which requires a lot of work, low efficiency and high cost and often requires skilled technical workers and the processed mirror It is inevitable there are tiny defects such as streaks or marks caused by abrasive particles exist. For this reason, in recent years
