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.”
🎯 Primary Application Fields
Granite platforms are primarily deployed in fields that demand exceptional stability and precision:
· Precision Measurement & Inspection
· Typical Uses: Base platforms for high-accuracy inspection equipment like Coordinate Measuring Machines (CMM) and optical vision measuring systems.
· Application Scenarios: Dimensional inspection of mechanical parts, mold acceptance, and precision measurement of electronics (e.g., PCBs, semiconductors).
· Key Advantage: The extreme flatness and stability of the platform itself form the reliable foundation for accurate measurement data.
· High-End Manufacturing & Machining
· Typical Uses: Base or motion platforms for precision CNC machine tools, laser processing equipment (cutting/welding), micro-assembly systems, and dispensing machines.
· Application Scenarios: Semiconductor wafer processing and inspection, optical component manufacturing, precision part machining, inspection of mobile phone/glass panels.
· 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.
· Scientific Research & Specialized Fields
· Typical Uses: Aerospace component testing, micro-gravity simulation, biomedical instrument R&D, precision optical experimental tables.
· Key Advantage: Non-magnetic, corrosion-resistant, and highly stable, meeting extreme requirements in specialized environments.
✨ Core Advantages & Performance
The suitability of granite for these critical roles stems from its inherent physical properties:
· Superior Stability: Natural stone has undergone millennia of natural aging, resulting in minimal internal stress and virtually no long-term deformation.
· Excellent Accuracy Retention: High hardness (Mohs 6-7, approximately 2-3 times that of cast iron) makes it extremely wear-resistant, maintaining micron-level (μm) accuracy over long periods.
· Low Environmental Sensitivity: Very low linear expansion coefficient (approx. 4.6×10⁻⁶/°C), making it highly resistant to temperature changes; also non-corrosive, non-magnetic, and resistant to most acids and alkalis.
🚀 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:
· 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/s²), long-travel precision linear motion, with repeatability reaching ±1 micron.
· 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.
📝 Selection and Usage Guidelines
Key considerations for choosing and using a granite platform:
Key Selection Parameters
· 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.
· Dimensions: Table size (e.g., 1000×750mm) and thickness must be chosen based on workpiece size and load.
· Load Capacity: Must support the weight of workpieces to ensure sufficient rigidity.
· Special Features: Requirement for custom machining like T-slots, threaded holes, or through-holes.
Usage and Maintenance Notes
· Environment: Ideal conditions are a temperature- and humidity-controlled, vibration-free, clean room.
· Installation: Must be leveled using matching supports and placed on a solid foundation.
· Operation: Handle workpieces gently; avoid impact or striking. Granite is hard but brittle, and edges can chip.
· Maintenance: Clean regularly with alcohol or water; no rust-proof oil is needed. Avoid prolonged exposure to humidity or strong acids/alkalis.
