High Stability Black Granite Bases
Precision granite components are foundational structural elements used in ultra-precision engineering systems such as coordinate measuring machines (CMM), semiconductor inspection equipment, optical alignment platforms, and high-end CNC machinery.
These components are manufactured from high-density black granite with exceptional dimensional stability, vibration damping characteristics, and extremely low thermal expansion behavior.
Each component is precision machined and inspected under controlled temperature environments to ensure long-term geometric stability and measurement reliability.

✔ Ultra High Stability
Granite provides natural stability over time, ensuring consistent measurement accuracy even under long operational cycles.
✔ Superior Vibration Damping
Internal grain structure effectively absorbs vibration energy, improving system stability in dynamic environments.
✔ Low Thermal Expansion
Minimal dimensional change under temperature variation ensures high repeatability in precision measurement systems.
✔ High Flatness & Precision Machining
Flatness can be controlled to micron-level tolerances depending on application requirements.
✔ Non-Magnetic & Corrosion Resistant
Ideal for semiconductor, optical, and electromagnetic-sensitive environments.
✔ Custom Engineering Capability
Custom sizes and complex structural geometries are available according to engineering drawings.
We use various techniques during this process:
● Optical measurements with autocollimators
● Laser interferometers and laser trackers
● Electronic inclination levels (precision spirit levels)

Q1: What are precision granite components used for?
They are used as structural bases in CMM, CNC machines, semiconductor inspection systems, and precision metrology platforms.
Q2: Why is granite used instead of steel or cast iron?
Because granite offers better vibration damping, lower thermal expansion, and superior long-term dimensional stability.
Q3: Can you manufacture custom shapes?
Yes. Components can be fully customized according to technical drawings and application requirements.
Q4: What accuracy levels can be achieved?
Depending on size and design, micron-level flatness and high precision geometric control can be achieved.
Q5: Is granite affected by temperature changes?
It has very low thermal expansion, making it highly stable under normal industrial conditions.
