Jul 20, 2019· Grinding wheels are dressed to restore or change their ability to remove stock or generate a specific finish. If the wheel is being used to remove stock, the grinding face is dressed to expose new and sharp cutting points, allowing the wheel to cut with a higher material removal rate. However, the tradeoff is that the finish may be unfavorable.
