what’s the méthode and equipment to be used to machined thé flange surface after rubber lining to obtain roughness Ra=3.2?
The way to properly finish a flange surface is to use a variable speed grinder with an 15-24 grit disc . You have to be careful as the grinder will kick back if not properly handled. In the hands of a skilled operator you can get flange faces easily within a tolerance of plus or minus 1mm by hand. As for the roughness there will be a texture to the flange but higher grits of disks will achieve finer and finer finishes.
