Ultra-Stable Granite Platform for High-Accuracy Motion and Metrology Systems

The UNPARALLELED® Precision Granite Base & Guide Structure is a high-stiffness, ultra-stable foundation engineered for precision motion systems, air bearing stages, coordinate measuring equipment, and advanced automation platforms. Manufactured from UNPARALLELED® high-density black granite, this structure delivers exceptional geometric stability, vibration damping, and long-term accuracy, making it a preferred choice for ultra-precision industries.

Designed for demanding environments where micron- and sub-micron accuracy is required, this granite structure integrates precision-ground reference surfaces with reinforced vertical guide elements, ensuring reliable performance throughout the entire lifecycle of the equipment.

Exceptional Dimensional Stability

Granite is inherently free from internal stress, unlike cast iron or welded steel. This ensures long-term flatness and squareness retention, even under continuous operation and varying environmental conditions.

Superior Vibration Damping

The natural crystalline structure of high-density granite provides excellent vibration absorption, improving motion smoothness and measurement repeatability in precision systems.

High Precision Machining

All reference surfaces are processed using advanced CNC grinding and lapping technology, achieving:

• High flatness and straightness
• Precise perpendicularity between base and guide surfaces
• Consistent geometry across large working areas

Integrated Guide & Mounting Design

The structure supports:

• Air bearing guides or linear motion systems
• Precision mounting of motors, encoders, and sensors
• Custom hole patterns and inserts based on customer drawings

Corrosion-Free & Non-Magnetic

Granite is rust-free, non-magnetic, and electrically insulating, making it ideal for sensitive metrology and semiconductor applications.

The UNPARALLELED® precision granite base is widely used in:

• Air bearing linear stages and motion platforms
• Coordinate Measuring Machines (CMMs)
• Semiconductor and lithography equipment
• Laser processing and optical inspection systems
• High-precision automation and assembly equipment
• Calibration platforms and reference structures
• Research laboratories and metrology institutes

Its modular and customizable design allows seamless integration into both OEM equipment and custom precision systems.

• Material: UNPARALLELED® high-density black granite
• Structure: Monolithic granite base with precision guide walls
• Surface finish: Precision ground / lapped working surfaces
• Accuracy grades: Available up to high-precision metrology standards
• Customization: Size, geometry, hole patterns, inserts, and accuracy upon request
• Compatibility: Suitable for air bearings, linear motors, optical scales, and precision fixtures

Each structure is manufactured under strict quality control systems compliant with ISO 9001, ISO 14001, and ISO 45001 standards.

One of the major advantages of granite structures is their low maintenance requirement:

• Clean working surfaces regularly using neutral detergent or alcohol
• Avoid sharp impacts to protect precision edges
• Maintain a stable temperature environment for optimal accuracy
• Periodically verify flatness and geometry in high-accuracy applications

Unlike metal structures, granite does not require rust prevention or repainting, significantly reducing long-term operating costs.

Why Granite Is the Preferred Material for vibration-dampingPrecision Engineering

Granite has been used in metrology for decades due to its thermal stability, wear resistance, and vibration damping properties. Compared to cast iron, granite offers:

• Lower thermal expansion
• Better long-term accuracy retention
• Improved environmental adaptability

These characteristics make granite the material of choice for modern ultra-precision manufacturing and measurement systems.
