How can surface form accuracy and surface quality be measured?

2026-08-25

We have a comprehensive suite of inspection methods: ① Surface‑profile interferometer: used to measure flatness (PV and RMS values). ② Surface defect inspection: under standard illumination, compare against reference samples to detect scratches and pitting in accordance with U.S. military standard MIL or Chinese national standard GB. ③ Thickness/parallelism measurement: employ dial indicators or laser thickness gauges to monitor dimensional consistency.
