Metallographic Abrasive Grinding

Grinding/polishing pressure is dependent upon the applied force (pounds or Newtons) and the area of the specimen and mounting material. Pressure is defined as the Force/Area (psi, N/m 2 or Pa). For specimens significantly harder than the mounting compound, pressure is better defined as the force divided by the specimen surface area.
