セラミック研磨
At Great Ceramic, we offer advanced ceramic grinding and polishing services tailored for high-performance applications in electronics, medical, aerospace, and more. Our expert team specializes in ceramic machining, precision surface finishing, and post-fired ceramic processing, ensuring every component achieves tight tolerances, flawless surface quality, and superior functional reliability.
Whether you’re fabricating zirconia shafts, alumina insulators, or custom ceramic housings, we are your partner for consistent quality and competitive turnaround.

Why Ceramic Grinding & Polishing Is Essential
Unlike traditional materials, technical ceramics are extremely hard, chemically inert, and thermally stable—but also brittle and difficult to machine. Therefore, advanced grinding and polishing techniques are required to:
We process both green body (pre-fired) and sintered (post-fired) ceramic parts with minimal material loss and maximum finish quality.
