Precision Challenges: Small vs. Large Granite Platforms
Granite precision platforms are the cornerstone of ultra-precision measurement, CNC machining, and industrial inspection. However, the size of the platform—whether small (e.g., 300×200 mm) or large (e.g., 3000×2000 mm)—significantly affects the complexity of achieving and maintaining flatness and...Read more -
How to Determine the Thickness of Granite Precision Platforms and Its Impact on Stability
When designing a granite precision platform, one of the key considerations is its thickness. The thickness of the granite plate directly affects its load-bearing capacity, stability, and long-term measurement accuracy. 1. Why Thickness Matters Granite is naturally strong and stable, but its rigid...Read more -
How to Choose Flatness Accuracy Grades for Granite Surface Plates
When selecting a granite precision surface plate, one of the most important factors to consider is its flatness accuracy grade. These grades—commonly marked as Grade 00, Grade 0, and Grade 1—determine how precisely the surface is manufactured and, therefore, how suitable it is for various applica...Read more -
Do Different Granite Origins Affect the Performance of Precision Platforms?
Granite is widely recognized as an ideal material for precision measuring platforms due to its exceptional stability, hardness, and resistance to temperature variations.
