High-Stability Granite Base

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

1. Extreme Stability & Rigidity

UNPARALLELED® Black Granite offers superior physical properties compared to common European and American black granites. Its low thermal expansion, high density and excellent wear resistance ensure long-term geometric accuracy even under demanding industrial conditions.

2. Ultra-Precision Machining

The base is processed using 6,000 mm ultra-large CNC grinders and hand-finished by technicians with 30+ years of experience. Surface accuracy can reach micro- and nano-level tolerances, making the structure ideal for precision motion systems.

3. Multi-Function Interface Design

The machine base incorporates:

Precision machined cavities

Multiple tapped insert patterns

Linear guide mounting surfaces

Air bearing installation points

Cable routing and sensor integration areas

All threaded inserts are installed with strict depth control and can be made flush upon customer request.

4. Excellent Vibration Damping

Granite's natural damping capability is significantly higher than metal, reducing resonance and improving accuracy for high-speed motion or scanning systems.

5. Corrosion-Free & Long Service Life

Unlike metal structures, granite does not rust, deform, or warp over time. The chemical stability of granite ensures reliable performance over decades of use.

This High-Stability Granite Base is widely used in fields where high positioning accuracy, repeatability and environmental stability are critical, including:

• Semiconductor equipment
• Precision laser machines (femtosecond, picosecond, cutting/marking systems)
• CMM and industrial metrology systems
• PCB micro-drilling machines
• Optical inspection equipment (AOI, industrial CT, X-Ray)
• XY Tables and linear motor stages
• Battery inspection and new energy equipment
• High-precision assembly lines

Its precision structure makes it a preferred solution for system integrators developing advanced motion platforms or semiconductor-level equipment.

Every High-Stability Granite Base is inspected with world-class metrology instruments, including:
Renishaw laser interferometers, WYLER electronic levels, Mahr µm-dial indicators, and Mitutoyo measurement systems. All calibration tools are traceable to national metrology institutes.

Our process complies with international standards such as DIN876, ASME, JIS, BS817, ensuring consistent global performance.

Granite components require minimal maintenance. To ensure the longest service life:

• Clean the surface regularly with non-acidic, lint-free cloths
• Avoid collisions with metal tools
• Protect the precision surfaces with dust covers when not in use
• Maintain a stable workshop temperature for critical measurement applications
• Re-calibrate periodically depending on usage environment
• Do not apply oils or corrosive liquids to granite surfaces

With proper care, UNPARALLELED® granite structures can maintain tolerances for decades.
