The Buehler grinder-polisher is for highly-reproducible mechanical polishing. The EcoMetTM 250 pro base features an 8-inch platen and a color touch-screen panel for recipe creation and storage. The AutoMetTM 250 power head provides variable head rotations in the single-force mode. It can grind or polish up to 6 one-inch-diameter specimens simultaneously.
The Vibro Met 2 vibratory polisher removes minor deformation remaining after mechanical polishing and generates a stress-free surface suitable for electron backscatter diffraction (EBSD). The samples are submerged in alumina or colloidal silica suspensions under the weight of 90 grams.
