Metrology Ceramics for CMM & Motion Control Equipment
Saint-Gobain Performance Ceramics & Refractories offers Silicon Carbide products based on Siliconized Silicon Carbide (SiSiC) and Nitride Bonded Silicon Carbide (NSiC) materials to deliver high accuracy and speed in industrial metrology. Used in CMM and Motion Control Equipment, silicon carbide offers many advantages over traditional ceramic materials.
- Lightweight (~20% less)
- High specific stiffness (~25% higher)
- Low thermal expansion (~50% less)
- High thermal stability
