grinding system for cross sectioning

Mechanical Cross Section | Semitracks

Analysts use two major methods for mechanical cross sectioning: potting the sample and grinding with abrasive compounds, and glass wheel cross sectioning. Potting and grinding with abrasive compounds can be performed on most any sample. Glass wheel cross sectioning requires that the die be removed from its package.
