Flatness is one of the most critical requirements in precision manufacturing. Whether producing optical components, semiconductor substrates, metallographic specimens, ceramic parts, or carbide tooling, poor flatness can affect assembly accuracy, surface quality, dimensional tolerances, and overall product performance.

Diamond grit size is one of the most significant factors influencing the performance of diamond debt cutting, grinding, and polishing tools. While operators in many applications may focus on machine settings, feed rates, or coolant conditions, they often ignore the fact that, like any material, diamond abrasive particle size is a fundamental requirement that dictates tool/material interaction.
