Granite Mechanical Structure

UNPARALLELED LTD is one of the leading manufacturers and suppliers of granite mechanical structure in China. With abundant experience, we warmly welcome you to buy advanced granite mechanical structure made in China here from our factory. We also accept custom orders.

This precision granite component is manufactured from UNPARALLELED® Black Granite, a high-density material (~3100 kg/m³) known for its exceptional stability, hardness, and long-term accuracy retention. Engineered for demanding ultra-precision applications, this granite structure delivers outstanding dimensional stability and vibration damping, making it ideal for semiconductor tools, automation systems, metrology equipment, and high-precision motion platforms.

At UNPARALLELED Group, every granite component is produced in our ISO9001, ISO45001, ISO14001, and CE-certified facilities using advanced CNC machining and manual lapping techniques performed by craftsmen with over 30 years of experience.

1. Superior Material: UNPARALLELED® Black Granite

• Density ≈ 3100 kg/m³, higher than American and European black granite
• Excellent thermal stability, ensuring reliable accuracy in temperature-controlled environments
• Naturally corrosion-resistant, non-magnetic, and non-conductive
• Zero internal stress and exceptional vibration damping performance

2. High Precision & Long-Term Stability

• Flatness and squareness can be produced to sub-micron or nanometer level
• Perfectly suited for high-resolution positioning systems, optical measurement, and semiconductor processing
• No rusting, deformation, or aging-guarantees long service life with minimal maintenance

3. Custom Machining & Functional Integration

• Multiple threaded inserts, bushings, and connection holes for mechanical or electrical integrations
• CNC-machined reference surfaces, mounting faces, and geometrical features
• Compatible with linear motors, air bearings, XY tables, and precision stages
• Supports fully customized geometries based on customer drawings

4. Manufactured in World-Class Facilities

• Processed on 20-meter large CNC gantry machines and 6-meter ultra-precision grinders
• All measurements traceable to National Metrology Institutes (NIM, PTB, NIST)
• Quality inspected using WYLER electronic levels, Renishaw laser interferometers, Mahr indicators, Mitutoyo gauges, and advanced roughness testers

This Granite Mechanical Structure is widely used in modern high-precision industries, including:

• Semiconductor Manufacturing Equipment

(Lithography systems, wafer inspection, metrology modules, optical waveguide positioning tools)

• Automation Technology & Robotics

(Granite machine base, granite mechanical components, automation machine structures)

• Industrial Metrology

(CMM machine bases, precision measurement frames, contour measurement, air-bearing platforms)

• Laser Processing & Optical Instruments

(Femtosecond/picosecond laser machines, AOI equipment, industrial CT/X-Ray systems)

• High-Precision CNC & Motion Platforms

(Linear motor stages, XY tables, ultra-precision assembly platforms)

Granite Mechanical Structure minimal maintenance, but proper handling ensures long-term stability:

1. Keep surfaces clean – Use lint-free cloths and alcohol-based cleaners; avoid oil contamination.
2. Prevent thermal shock – Do not expose the granite to rapid temperature changes.
3. Protect precision surfaces – Do not place metal tools directly on the reference planes.
4. Periodic inspection – Perform calibration using WYLER levels or professional gauges annually, depending on usage.
5. Avoid vibration & impact – Granite can chip if struck by heavy metal objects.

With proper care, precision granite structures can maintain accuracy for decades.
