HandiMet 2 Grinding Techniques
Grinding techniques vary with the individual operator. For proper grinding and for best sample
surface results, follow these suggestions.
•
Grasp the sample firmly in the fingertips.
•
Apply a uniform but firm pressure to the sample against the abrasive surface.
•
Draw the sample over the abrasive surface from the back to the front in a straight, even
motion. A back and forth motion usually leads to an undesirable curved surface.
•
Make as many strokes as required to remove all visible scratches. Continue with several
additional strokes until the previous scratches have been removed.
•
Proceed from the coarsest grit (240) to the finest grit (600) for fine grinding.
•
Rotate the specimen 90 degrees between each step so the grinding is perpendicular to the
previous scratches. This will provide a clear indication o how the grinding is progressing.
•
Rinse the sample between each step to remove the abrasive particles. Ultrasonically clean
the sample thoroughly after the last grinding step (600 grit).
•
Change the abrasive paper when the paper becomes worn or when changing to a different
material, i.e. steel to aluminum.

Maintenance
The HandiMet 2 will continue to perform at optimum levels with proper care, daily cleaning, and general
maintenance.
•
Wipe exposed surfaces with a clean damp cloth after each use or at the end of the day. This will
reduce the possibility of coarse abrasive grit particles from contaminating the finer grit papers.
