High-precision granite platforms, leveraging the unique physical properties of natural stone, have become a critical foundation in industries with extreme accuracy demands. They serve not only as the ultimate “measurement datum” but also as core components in various types of “precision motion systems.”
π― Primary Application Fields
Granite platforms are primarily deployed in fields that demand exceptional stability and precision:
Β· Precision Measurement & Inspection
Β· Typical Uses: Base platforms for high-accuracy inspection equipment like Coordinate Measuring Machines (CMM) and optical vision measuring systems.
Β· Application Scenarios: Dimensional inspection of mechanical parts, mold acceptance, and precision measurement of electronics (e.g., PCBs, semiconductors).
Β· Key Advantage: The extreme flatness and stability of the platform itself form the reliable foundation for accurate measurement data.
Β· High-End Manufacturing & Machining
Β· Typical Uses: Base or motion platforms for precision CNC machine tools, laser processing equipment (cutting/welding), micro-assembly systems, and dispensing machines.
Β· Application Scenarios: Semiconductor wafer processing and inspection, optical component manufacturing, precision part machining, inspection of mobile phone/glass panels.
Β· Key Advantage: High rigidity dampens vibrations, while a low coefficient of thermal expansion resists dimensional changes from temperature fluctuations, ensuring process stability and product quality.

Β· Key Advantage: Non-magnetic, corrosion-resistant, and highly stable, meeting extreme requirements in specialized environments.
β¨ Core Advantages & Performance
The suitability of granite for these critical roles stems from its inherent physical properties:
Β· Superior Stability: Natural stone has undergone millennia of natural aging, resulting in minimal internal stress and virtually no long-term deformation.
Β· Excellent Accuracy Retention: High hardness (Mohs 6-7, approximately 2-3 times that of cast iron) makes it extremely wear-resistant, maintaining micron-level (ΞΌm) accuracy over long periods.
Β· Low Environmental Sensitivity: Very low linear expansion coefficient (approx. 4.6Γ10β»βΆ/Β°C), making it highly resistant to temperature changes; also non-corrosive, non-magnetic, and resistant to most acids and alkalis.
π Technology Evolution: From Static Base to Dynamic Core
Beyond static measurement platforms, granite is now deeply integrated into advanced motion systems, mainly in two forms:
Β· Granite Linear Modules/Motion Stages: Utilize a granite base for high rigidity, integrated with linear motors and guides. Enable high-speed (>0.2m/s), high-acceleration (up to 5 m/sΒ²), long-travel precision linear motion, with repeatability reaching Β±1 micron.
Β· Granite Air Bearing Platforms: Employ air bearings on a granite surface to achieve contactless and frictionless motion. Offer repeatability down to 0.2 microns and are completely oil-free, designed for ultra-clean environments like semiconductor inspection and optical metrology.
π Selection and Usage Guidelines
Key considerations for choosing and using a granite platform:
Key Selection Parameters
Β· Accuracy Grade: National standards (e.g., Chinese GB) classify as 000, 00, 0, 1. Grade 000 is the highest, suitable for top-tier metrology labs.
Β· Dimensions: Table size (e.g., 1000Γ750mm) and thickness must be chosen based on workpiece size and load.
Β· Load Capacity: Must support the weight of workpieces to ensure sufficient rigidity.
Β· Special Features: Requirement for custom machining like T-slots, threaded holes, or through-holes.
Usage and Maintenance Notes
Β· Environment: Ideal conditions are a temperature- and humidity-controlled, vibration-free, clean room.
Β· Installation: Must be leveled using matching supports and placed on a solid foundation.
Β· Operation: Handle workpieces gently; avoid impact or striking. Granite is hard but brittle, and edges can chip.
Β· Maintenance: Clean regularly with alcohol or water; no rust-proof oil is needed. Avoid prolonged exposure to humidity or strong acids/alkalis.
