关于确定最低许用表面光洁度,可以利用以下1～4表中所列的资料,即根据名义尺寸、精度等级和选择的公差配合来确定最低许用表面光洁度,此资料没有排除更高的表面光洁度应用的可能性(与表中推荐的比较)。但是为避免生产的成本太高起见,其仅用於技术上有根据的场合。关于光洁度 For the purpose of determining the minimum allowable surface finish, the information listed in Tables 1 to 4 below can be used to determine the minimum allowable surface finish based on nominal size, accuracy grade, and selected tolerance fit. This information does not preclude higher surface finish Possibility of application (as recommended in the table). However, to avoid too much production costs, it is only used for technically based applications. About the finish
