Lapping & Polishing Titanium - Case Study Test Requirements: To mirror polish and lap titanium components with a process that causes as little roll o? as possible Component/Material: 20 x 1/8” titanium diameter rods. Process for producing mirror ?nish to Titanium Using the PR3 plate gives you the best plate polish, whilst leaving the edges nice and sharp. We tried to keep the CMP process time to a minimum and used a di?erent type of polishing pad to try and minimise edge roll o?. We stopped the process after each minute and examined parts under a microscope for scratches. After 3 minutes of pad polishing, the scratches disappeared. Ra was estimated at better than 0.02 µm.
