Firstly,to make the workpiece basic processed use the lathe tool in general machine tool,then,use tbe cutter of hawking metal mirror surface finishing equipment to process it again,the surface will reach less than Ra0.2 easily,the mico hardness will be improved 20%,the wear resisitance will be improved significant and the life will be improved 5 ~10 times.further more,the cost will be reduced more than 5 times.
