When it is installed on the machine and rotated, polish it repeatedly from the outside to the inside until the inside and outside wear marks are unified. Then use fine sandpaper to grind it finely (150-320#, etc. as needed). Stick the diamond powder mixed with diamond oil into a paste on the sandpaper, rub it onto the copper polishing disc, and continue polishing. During the polishing process, you need to add mixed powder and oil to keep the disc surface moist until the polished disc surface turns black evenly. It can be polished or used with green light powder.Package included:1PC grinding wheel==========High-concerned chemical : NoneOuter Diameter : 200mmUse : Commercial ManufacturePad Material : diamond
