ブラックシリコンカーバイドマクロ vs. マイクロ: 粒子サイズが表面仕上げ Ra 値に与える影響
Choosing the wrong particle size range for black silicon carbide processing can leave surface finish Ra values 8 に 15 times above specification. This guide maps FEPA macro and micro grit grades to achievable Ra ranges, explains the physical mechanisms behind each transition, and gives engineers a practical framework for selecting the right grade from first principles.
