medium sits on the top of a working disc. A series of grinding steps follow whereby each new step makes use of an even finer polishing medium to proceed step by step towards the grade of the polished surface desired. During the whole process, a lubricating and cooling fluid ensures that the sample is cooled, and the waste material is washed away.  

The last scratches are polished by removing a final layer. This step is the most important with a diamond suspension in poly or mono for getting mirror finish polishing to check in microscopy. 

Program control helps to record every process and give repeatable results at all times. 

Polishing is a vital step in the sample preparation process, aiming to attain a reflective flat surface while eliminating scratches and defects. This enables microscopic analysis and hardness testing for the final inspection of microstructural analysis.
