FAQ's of Granite Surface Plate:

Q: How is the flatness of the Granite Surface Plate maintained over time?

A: The plate is made from high-density black granite, which resists wear and minimizes thermal expansion (6 x 106/C). Proper chamfered edges and rigid structure ensure the surface remains exceptionally flat, while periodic calibration assures conformity to Grade 0 or relevant standards.

Q: What is the standard process for using a granite surface plate for inspection?

A: Place the plate on a stable surface or use optional steel stands/leveling bolts. Clean the surface and use precision measuring instruments such as dial indicators or height gauges. Regularly check for contaminants or damage to maintain measurement accuracy.

Q: When should I choose a granite surface plate over a cast iron alternative?

A: Granite is non-magnetic, highly wear-resistant, non-corrosive, and provides extra-fine smooth surfaces. It's ideal for environments where magnetic interference or rust could affect accuracy, and where high flatness stability is required for long-term precision measurements.

Q: Where can the granite surface plate be installed for optimal performance?

A: Install the plate in a temperature- and humidity-controlled environment, such as a standard room or metrology laboratory. Position it on stands, benches, or a pedestal to minimize vibrations and ensure stable, precise measurement results.

Q: What accessories are available with the granite surface plate?

A: Optional accessories include robust steel stands, leveling bolts for precise height adjustment, and protective covers to shield against dust and scratches. These help maintain the plate's accuracy and durability across various workspaces.

Q: How does the surface plate benefit precision inspection and tool making?

A: Its high flatness tolerance, non-magnetic properties, and resistance to environmental factors ensure reliable, repeatable measurement references. This boosts productivity, reduces errors, and improves quality control for inspection, layout, and tool making applications.
