kaloMAX NT II S3 Spherical cap grinder for the determination of layer thicknesses of single layers and layer systems Method: For a wide variety of samples, coating thickness measurements with calotte grinders has been an established method for many years. A hardened steel ball moistened with an abrasive slurry is set in motion by the motor-driven shaft, which grinds a spherical cap in the sample – the so-called calotte. If the coating is ground completely through, each individual layer can be identified under the microscope as a concentric ring (flat sample) or ellipse (cylindrical sample). By...
