The granite table provides a stable, flat, and vibration-dampening reference surface for the CMM. It supports the workpiece and serves as the datum for all measurements, ensuring accuracy and repeatability.
Typical flatness is 0.001–0.003 mm/m (per ISO 1101) and surface roughness is 0.4–0.8 μm Ra (per ISO 4287). These are reference ranges; confirm exact values for your specific model.
Granite has a low thermal expansion coefficient, but temperature variations can still cause dimensional changes. The operating temperature range is 10–40 °C, with a stability of ±0.1 °C/h. Maintaining stable temperature is crucial for measurement accuracy.
Regular cleaning to remove debris and contaminants, periodic inspection for cracks or wear, and ensuring proper leveling and environmental control. Verify specifications with the manufacturer for specific maintenance intervals.
