Key Considerations for Granite Surface Plates

When selecting or buying granite surface plates, there are several key considerations to keep in mind:

1. Accuracy and Flatness: Granite surface plates are known for their high accuracy and flatness. Ensure that the surface plate meets the required accuracy standards for your application.

2. Size and Thickness: Choose a surface plate size and thickness that are suitable for the parts you will be measuring or inspecting. Consider the weight capacity of the surface plate as well.

3. Grade of Granite: Granite surface plates are available in different grades based on their overall quality and flatness. Higher grades offer better accuracy and stability.

4. Surface Finish: The surface finish of the granite plate should be smooth and free from defects that could affect measurements.

5. Edge Finish: Look for surface plates with precision-ground edges to ensure accuracy when measuring close to the edge of the plate.

6. Calibration and Certification: Consider the availability of calibration services and whether the surface plate comes with a calibration certificate for traceability.

7. Handling and Maintenance: Evaluate the transportation and handling requirements of the surface plate, as well as the recommended cleaning and maintenance procedures to ensure its longevity.

8. Manufacturer Reputation: Choose a reputable manufacturer or supplier with a track record of producing high-quality granite surface plates.

By considering these factors, you can select a granite surface plate that meets your requirements for accuracy, reliability, and durability in your industry.
