This light weight, bench top Grinding/Polishing model is ideal for surface preparation of small metallographic specimens. It is adjustable in speed from 0 to 1725 RPM, and has ⅓ HP and it is fully grounded. The coolant is applied to the wheel through an adjustable flow control goose-neck spout.
Abstract. A simple two piece grinding/polishing tool permits controlled thinning of samples mounted on round petrographic glass slides. The tool consists of a body with a finely-threaded axial hole and an adjusting screw to control sample thickness. 2 references, 1 figure.
When a sample is dry ashed, a fine residue (ash) is often formed. The small particles in the residue are resuspended readily by any air flow over the sample. Air flows are generated by changes in temperature (e.g., opening the furnace while it is hot) or by passing a stream of gas over the sample during heating to assist in combustion.
As well as overfilling vessels, processing very small samples in larger grinding vials can also lead to inefficient homogenization. In such instances, it may be necessary to process the samples for a longer period of time. Grinding media used during bead beating can be divided into beads, grinding balls, ceramic satellites and/or grinding ...

Plane grinding with diamond is the best choice to ensure flat samples from the very beginning of the preparation. Fine grinding with either MD-Largo or MD-Allegro will provide the best possible planeness. To avoid relief, preparation time and the type of polishing cloth used are the most important parameters.

Remember, any time the grinder makes noise against a slide, you are removing rock. You often don't have to advance the wheel at all to just grind a small thickness away. If your section comes out with the minerals all cracked: you were grinding too fast. If your section comes out with the edges thin and the center thick: you were grinding too fast.
