Q: What is a granite platform?
A: A granite platform is a precision reference surface machined and hand-ground from natural rock (typically black, fine-grained granite). It serves as the “standard ruler” in metrology labs and workshops, primarily used for precision measurement, inspection, layout marking, and assembly in industrial production.
Q: Why choose granite over steel or cast iron for measuring platforms?
A: Granite offers the following unique advantages:
• Excellent stability: Its rock structure remains stable, resisting deformation over extended use.
• Rustproof and corrosion-resistant: Unaffected by coolants or oils, preventing rust contamination of workpieces.
• Non-magnetic: Suitable for measuring magnetic materials or precision electronic components.
• Thermal stability: Low thermal expansion coefficient minimizes temperature-induced shifts.
• High hardness: Excellent wear resistance ensures long-term dimensional accuracy.
• Vibration damping: Natural stone possesses inherent shock-absorbing properties.Q: Is all granite suitable for platforms?
A: No. Only high-quality natural granite with fine-grained, uniform texture, free of cracks and impurities should be selected. Common premium materials include China's “Jinan Green” and India's “Black Granite.” Coarse-grained stones or those with excessive quartz veins are prone to weathering and poor precision retention.
Q: How should the platform be supported? Can it rest directly on the ground?
A: It cannot rest directly on the ground. Specialized supports must be used.
• Three-point support: The standard support configuration is three-point, typically positioned at points 2/9 of the length from each end. This minimizes planar deformation caused by self-weight.
• Leveling: Supports usually feature adjustable feet for platform leveling.Q: Can surface scratches be repaired?
A: Yes. Minor scratches can be removed by professionals using oilstone grinding. If accuracy is compromised, the platform must be returned to the factory for regrinding and recalibration. Note that each regrinding reduces the platform's thickness.
