Manual Fine Grinding is performed by drawing the specimens in one direction across the surface of the water lubricated abrasive paper. (Back to front is recommended) Use of backward and forward motion is less desirable because there is a tendency to rock the sample, producing a curved rather than a flat surface. ...
