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:

  • Achieve ultra-smooth, mirror-like surface finishes (Ra < 0.02 μm)

  • Improve dimensional stability and ensure high-precision assembly
  • Enhance wear resistance, chemical durability, and cleanliness
  • Reduce microcracks and increase fatigue resistance
  • Ensure compatibility with vacuum, optical, and high-voltage applications

We process both green body (pre-fired) and sintered (post-fired) ceramic parts with minimal material loss and maximum finish quality.
