Granite surface plates are widely used in industrial manufacturing and measurement applications due to their excellent stability, durability, and precision. To ensure optimal performance, proper installation and maintenance are essential. Below is a complete guide to help you understand the features and setup process of granite surface plates.
How to Install and Adjust a Granite Surface Plate
Unpacking and Inspection
Upon receiving your granite surface plate, carefully remove all packaging and check for any visible damage or chipping.
Precision Surface Location
Please note: the top surface of the granite plate is the calibrated precision surface. Handle with care during placement.
Mounting the Plate on a Stand
If a special granite plate stand is required, use a forklift to gently position the plate onto the stand. Ensure even placement.
Leveling the Plate
If the surface appears uneven or unbalanced, use the five leveling screws on the stand to make fine adjustments. In cases of uneven flooring, the stand's adjustable bolts at the base can help achieve proper alignment.
Cleaning the Surface
Clean the top surface thoroughly with a soft cloth to remove dust, debris, or any particles that may affect measurement accuracy.
Final Check
After confirming the plate is level and clean, it is ready for precise inspection or measurement tasks.
Key Features and Advantages of Granite Surface Plates
High Density & Smooth Finish
Fine-grained structure ensures excellent wear resistance and a low surface roughness.
Naturally Aged Material
The granite undergoes natural aging over the years, eliminating internal stress and providing long-term dimensional stability.
Corrosion & Chemical Resistance
The surface is non-magnetic, acid/alkali-resistant, and immune to rust or corrosion.
Low Thermal Expansion
Minimal expansion under temperature changes ensures consistent measurement accuracy.
Impact Resistant
When scratched or bumped, only minor dents may occur-no raised burrs, so measurement results remain unaffected.
Granite Surface Plate Leveling Procedure
Place the granite plate directly on a clean, flat floor and manually adjust the four feet to ensure basic stability.
Mount the plate onto the supporting stand, aligning support points symmetrically to ensure balanced weight distribution.
Pre-adjust the support screws evenly so that the load is uniformly shared among all points.
Use a level gauge (spirit level or electronic level) to verify horizontal alignment, and adjust the relevant screws to bring the plate into a level position.
After the initial adjustment, allow the plate to settle for 12 hours. Recheck and adjust if necessary before official use.
Regular maintenance and recalibration should be performed based on environmental conditions and usage frequency.
