블랙 실리콘 카바이드 매크로 대. 마이크로: 입자 크기가 표면 마감 Ra 값에 미치는 영향
Choosing the wrong particle size range for black silicon carbide processing can leave surface finish Ra values 8 에게 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.
