Causes of Accuracy Loss in Granite Surface Plates
Granite surface plates are essential tools for high-precision measurement, layout marking, grinding, and inspection in mechanical and industrial applications. They are valued for their hardness, stability, and resistance to rust and corrosion. However, improper use, poor maintenance, or incorrect installation can lead to gradual precision loss.
Main Causes of Wear and Accuracy Reduction
-
Improper Usage – Using the plate to measure rough or unfinished workpieces can cause surface abrasion.
-
Unclean Work Environment – Dust, dirt, and metal particles increase wear and affect measurement accuracy.
-
Excessive Measuring Force – Applying too much pressure during inspection can deform the plate or cause early wear.
-
Workpiece Material & Finish – Abrasive materials like cast iron can accelerate surface damage, especially if unfinished.
-
Low Surface Hardness – Plates with insufficient hardness are more prone to wear over time.
Reasons for Precision Instability
-
Improper Handling & Storage – Dropping, impact, or poor storage conditions can damage the surface.
-
Normal or Abnormal Wear – Continuous heavy use without proper care speeds up precision loss.
Installation & Foundation Issues
If the base layer is not properly cleaned, moistened, and leveled before installation, or if cement slurry is applied unevenly, hollow spots may form under the plate. Over time, these can cause stress points that affect measurement accuracy. Proper alignment during installation is essential for stable performance.
Maintenance Recommendations
-
Clean the plate before and after use to avoid particle contamination.
-
Avoid placing rough or unfinished parts directly on the surface.
-
Apply moderate measuring force to prevent surface deformation.
-
Store in a dry, temperature-controlled environment.
-
Follow proper installation and alignment procedures.
By following these guidelines, granite surface plates can maintain high precision for many years, ensuring reliable results in industrial production, inspection, and laboratory applications.
