Non-Metallic Granite Machine Components | Custom Granite Base for Metrology and Automation

What Are Granite Components?

Granite components are precision-engineered measuring bases made from natural granite stone. These parts serve as fundamental reference surfaces in a wide range of precision inspection, layout, assembly, and welding operations. Often used in metrology labs, machine shops, and manufacturing lines, granite components provide an extremely stable and accurate working platform that resists rust, deformation, and magnetic interference. Thanks to their high flatness and dimensional integrity, they are also widely used as bases for mechanical testing equipment.

Key Features of Granite Components

• Dimensional Stability: The structure of natural granite has gone through millions of years of geological formation, ensuring minimal internal stress and outstanding long-term dimensional consistency.

• Excellent Hardness & Wear Resistance: Granite has high surface hardness, making it highly resistant to abrasion, scratches, and environmental wear.

• Corrosion & Rust Resistant: Unlike metal workbenches, granite does not corrode or rust, even under humid or chemically aggressive conditions.

• No Magnetism: These components do not get magnetized, making them ideal for use with sensitive instruments or in high-precision environments.

• Thermal Stability: With a very low coefficient of thermal expansion, granite remains stable under room temperature fluctuations.

• Minimal Maintenance: No oiling or special coatings are required. Cleaning and general maintenance are simple, reducing long-term upkeep costs.

What Materials Are Granite Components Made From?

These components are made from high-density, fine-grained black granite, selected for its exceptional stability and wear resistance. The granite is quarried, naturally aged, and precision-machined using high-end equipment to achieve tight tolerances in flatness, squareness, and parallelism. Granite materials used typically have a density of 2.9–3.1 g/cm³, significantly higher than decorative or architectural-grade stone.

Common Applications of Granite Components

Granite mechanical components are widely utilized in industries such as:

• Precision Measuring Equipment Bases

• CNC Machine Foundations

• Coordinate Measuring Machines (CMM) Platforms

• Metrology Laboratories

• Laser Inspection Systems

• Air Bearing Platforms

• Optical Device Mounting

• Custom Machinery Frames and Beds

They can be customized with features like T-slots, threaded inserts, through holes, or grooves based on customer requirements. Their non-deforming nature makes them ideal for high-precision tasks that require a reliable reference surface over time.
