Understanding the Flatness Tolerance of 00-Grade Granite Surface Plates
In precision measurement, the accuracy of your tools depends largely on the quality of the reference surface beneath them. Among all precision reference bases, granite surface plates are widely recognized for their exceptional stability, rigidity, and resistance to wear. But what defines their le...Read more -
Can Mounting Holes on Granite Surface Plates Be Customized?
In the field of precision measurement and machine assembly, the granite surface plate plays a fundamental role as the reference foundation for accuracy and stability. As equipment designs become increasingly complex, many engineers often ask whether the mounting holes on granite surface plates ca...Read more -
Why CMM Granite Surface Plates Demand Higher Flatness and Rigidity
In precision metrology, the granite surface plate is the foundation of measurement accuracy. However, not all granite platforms are the same. When used as the base for a Coordinate Measuring Machine (CMM), the surface plate must meet far stricter flatness and stiffness standards than ordinary ins...Read more -
Can a Jointed Granite Surface Plate Maintain High Precision?
In precision measurement, one common challenge arises when the workpiece to be inspected is larger than a single granite surface plate. In such cases, many engineers wonder whether a jointed or assembled granite surface plate can be used and if the joint seams will affect measurement accuracy. Wh...Read more -
The Critical Role of T-Slot Design in Granite Precision Platforms
A granite precision platform, with its inherent stability and dimensional accuracy, forms the foundation of high-level metrology and assembly tasks. For many complex applications, however, a simple flat surface isn’t enough; the ability to securely and repeatably clamp components is vital. ...Read more -
The Critical Role of Chamfered Edges on Precision Granite Platforms
In the world of metrology and precision assembly, the primary focus is, rightly, on the flatness of the granite platform’s working surface. However, manufacturing a truly high-quality, durable, and safe surface plate requires attention to the edges—specifically, the practice of chamfering o...Read more -
Why Granite Platform Thickness is the Key to Load Capacity and Sub-Micron Accuracy
When engineers and metrologists select a precision granite platform for demanding measurement and assembly tasks, the final decision often centers on a seemingly simple parameter: its thickness. Yet, the thickness of a granite surface plate is far more than a simple dimension—it is the foundation...Read more -
Engineered for Endurance: How Low Water Absorption Guarantees the Stability of Precision Granite Platforms
The need for dimensional stability in high-precision measurement is absolute. While granite is universally lauded for its thermal stability and vibration damping, a common question arises from engineers in humid climates: How does moisture affect a precision granite platform? It’s a valid concern...Read more -
Why Precision Granite Platforms Are Non-Negotiable for EMI Testing and Advanced Metrology
The Invisible Challenge in High-Precision Measurement In the world of advanced manufacturing, electronic testing, and sensor calibration, success hinges on one thing: dimensional stability. Yet, even the most rigorous setups face a silent disruptor: electromagnetic interference (EMI). For enginee...Read more -
Protecting Large-Scale Granite Components During Global Transit
The Challenge of Transporting Multi-Ton Accuracy Purchasing a large-scale precision granite platform—especially components capable of supporting a 100-ton load or measuring up to 20 meters in length, as we produce at ZHHIMG®—is a significant investment. A critical concern for any engineer or proc...Read more -
Ranking the Costs of Precision—Granite vs. Cast Iron vs. Ceramic Platforms
The Material Cost Challenge in Ultra-Precision Manufacturing When sourcing a foundation for critical metrology equipment, the choice of material—Granite, Cast Iron, or Precision Ceramic—involves balancing upfront investment against long-term performance and stability. While engineers prioritize s...Read more -
The Substitution Question—Can Polymer Precision Platforms Replace Granite in Small-Scale Metrology?
The False Economy of Material Substitution In the world of precision manufacturing, the quest for cost-effective solutions is constant. For small-scale inspection benches or localized testing stations, a question frequently arises: Can a modern Polymer (Plastic) Precision Platform realistically s...Read more
