Technical Parameter Comparison Table: Granite Platform vs. Traditional Metal Platform for CMM
| Technical Parameter | Granite Platform | Traditional Metal Platform (Cast Iron/Steel) | Core Advantages |
| Coefficient of Linear Expansion | (8~9)×10⁻⁶/℃ | (11~12)×10⁻⁶/℃ | Minimal impact from ambient temperature fluctuations, ensuring long-term measurement accuracy stability |
| Flatness Tolerance | Grade 00: ≤2μm/m; Grade 0: ≤5μm/m | Grade 00: ≤8μm/m; Grade 0: ≤12μm/m | Higher reference surface flatness, providing precise support for CMM measurements |
| Rigidity Modulus | Approximately 90~100GPa | Approximately 70~80GPa | High rigidity against deformation, no warping after loading workpieces, ensuring measurement accuracy |
| Wear Resistance | Dense natural structure, high wear resistance | Prone to wear, surface accuracy declines after long-term use | Longer service life, reducing costs of frequent maintenance and precision calibration |
| Magnetic Resistance / Conductivity | Non-magnetic, non-conductive | Magnetic, highly conductive | Avoids interfering with CMM probe signals, suitable for high-precision testing scenarios |
| Corrosion Resistance | Acid and alkali resistant, no rusting | Prone to oxidation and rusting, requiring regular anti-rust treatment | Adapts to complex workshop environments, reducing maintenance frequency |
