Metallographic Grinding Machines & Polishing Machines - ATM

Grinding and polishing is the final stage in the sample preparation process and consists of several steps. Each step uses finer abrasive than the previous one, the ultimate goal being to produce a deformation-free, scratch-free and highly reflective sample surface.

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.
