Ceramic block gauge/ceramic testing platform/ceramic plug gauge/ceramic ring gauge/ceramic needle gauge: Isostatically pressed zirconia ceramics are used. Compared with metal materials, the standard size of zirconia ceramics is not affected by environmental changes and has high wear resistance. Corrosion resistance, high toughness; the material production size and surface can achieve accuracy above standard specifications; after hardening, the deformation is small; antistatic, non-magnetic, non-conductive;

Machinable accuracy: the flatness of the ceramic testing platform is less than 0.0020mm; the tolerance of the plane, axis and inner diameter can be controlled within 0.002mm;
