Surface grinding is a process that moves a grinding wheel or segment in a plane while the wheel contacts the work piece and removes material to create a flat surface. Parts may require surface grinding to achieve a flat surface, a very accurate thickness, a very smooth surface, material removal for hard materials and when material needs to be removed quickly.
