Ceramics in precision equipment combine the comprehensive characteristics of both metals and stone.<\/p>\n\n\n\n

I. Similar advantages compared to stone (granite \/ commonly used ceramic bases)
High dimensional stability, extremely low thermal expansion
Like granite, the thermal expansion coefficient is extremely small, making it resistant to deformation under temperature changes. Precision measurement and laser equipment maintain long-term operational accuracy without drift; it eliminates positioning errors caused by the thermal expansion and contraction of metals.
High rigidity, good vibration damping
The internal dense ceramic crystal structure offers better damping performance than most metals, with fast vibration attenuation. Like granite, it can suppress equipment processing\/detection vibrations to improve accuracy.
Corrosion resistance, rust-proof, resistant to chemical erosion
It does not oxidize and is not corroded by cutting fluids or acid-base cleaners. Unlike steel, it does not rust easily and requires no electroplating for corrosion protection, being as environmentally corrosion-resistant as stone.
Insulation, non-magnetic
Alumina and silicon carbide ceramics are non-conductive and non-magnetic, producing no electromagnetic interference. They are suitable for optical, semiconductor, and precision inspection equipment. Stone is also non-magnetic and insulating, whereas most metals are conductive and magnetic.
Wear resistance, difficult to scratch
Its hardness far exceeds ordinary steel, and the surface is wear-resistant. Long-term sliding of tooling or bolt assembly is unlikely to cause indentations or scratches, with wear resistance properties approaching high-hardness stone.<\/p>\n\n\n\n

II. Unique similar advantages compared to metals (steel, aluminum, alloys)
Precisely machinable, stronger formability
Granite can only be drilled and grooved; ceramics can be precisely ground, polished, drilled, tapped, and formed into thin-walled complex structures with micron-level precision. Like metals, they can be customized into irregular, ultra-thin, and integrated structural components.
Controllable weight, outstanding lightweight advantage
Under the same rigidity, the density is far lower than steel and thinner than granite, making it suitable for high-speed motion modules. Its lightweight characteristics match aluminum alloy metal components, whereas stone generally has a heavy self-weight.
Strong assembly adaptability
Metal threaded inserts can be embedded, through-holes\/countersunk holes can be machined, and isolation pillars can be installed. It is compatible with bolt tightening assembly methods, sharing the same assembly logic as metal components; granite’s hole drilling is limited, and small holes easily chip at the edges.
High compressive strength, strong local load-bearing capacity
It has excellent compressive performance and can withstand high-intensity bolt tightening pressure. Unlike stone, it does not easily crack at thin-walled sections, with load-bearing performance approaching that of cemented carbide.<\/p>\n\n\n\n

III. Unique comprehensive advantages of ceramics that neither metals nor stone possess
Almost no creep, meaning it will not slowly deform under long-term load-bearing. This is superior to metals (which creep under long-term pressure) and natural stone (where natural minerals have micro-stress creep);
The surface is dense and non-absorbent, meaning it will not adsorb dust or oil. It is easy to clean and will not contaminate optical lenses like liquid seepage in stone;
Uniform and homogeneous, it has no internal cracks or mineral impurity hazards found in natural stone. The consistency of dimensions and performance across entire product batches is far better than granite;
High-temperature resistance, maintaining stable strength and accuracy under high-temperature working conditions, whereas aluminum and steel easily soften and deform at high temperatures.<\/p>\n\n\n\n

IV. Typical application scenarios in precision equipment
Semiconductor inspection bases, laser machine tool platforms, CMM modules, optical lens brackets, and high-precision transmission isolation pillars, perfectly replacing traditional granite bases and metal aluminum alloy tooling.<\/p>\n\n\n\n
