Dressing or Truing What's the Difference? — Continental

Jun 20, 2017 · A superabrasive grinding wheel is largely self-sharpening, although the workpiece material can cause it to dull or load-up. In such situations the grit starts to either rub against the surface or plow, (pushing material aside). Both affect surface finish, increase cutting forces and create heat, which can damage the workpiece.
