Precision Equipment: Material Selection Comparison of Ceramics, Metals, and Granite Complete Selection LogicI. Overview of Core Characteristics (Quick Differentiation) Performance Requirement Granite Metal Precision Ceramic Large stationary base, cost-sensitive ✅ First choice ❌ Not recommended Alternative (higher cost) Lightweight high-speed moving components ❌ Excessively heavy ✅ Top pick for standard precision ✅ Top pick for…

Ceramics in precision equipment combine the comprehensive characteristics of both metals and stone. I. Similar advantages compared to stone (granite / commonly used ceramic bases)High dimensional stability, extremely low thermal expansionLike 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…
