  • Diamond Suspensions – Best Practices for Precision Polishing

    In fine grinding and polishing, diamond suspensions play a critical role in controlling scratch depth, surface uniformity, and overall finish quality. Consistent particle size distribution and proper lubrication help achieve repeatable results, especially on hard materials like ceramics, carbides, optical glass, and gemstones.

    Key factors that seem to matter most are grit selection, pad compatibility, and maintaining a clean, well-conditioned surface to avoid rogue scratches. This reference gives a good overview of different suspension grades and applications: https://ukam.com/product/diamond-suspensions/

    Interested to hear what grit progressions and pad types others here prefer for achieving the best balance between removal rate and surface quality.
