GRINDING & POLISHING

Grinding/polishing pressure is dependent upon the applied force (Newtons) and the area of the specimen and mounting material. Pressure is defined as the Force/Area (N/m2). For specimens significantly harder than the mounting compound, pressure is better defined as the force divided by the specimen surface area.
