Precision Machining Equipment

Precision machining equipment is core of manufacturing industry, whether it is laser processing, milling, drilling, grinding or electrical discharge processing, granite due to its physical properties has distinct advantages that cannot be achieved by cast iron/steel or synthetic stone. The combination of technologies allows for previously unimaginable precision. Other advantages of granite include high vibration damping, limited expansion coefficient, low thermal conductivity and a weight ratio close to that of aluminum.

We provide granite materials of different origins and properties, suitable for different industries and needs, such as Jinan black and Indian black. Utilizing the grinding technology and expertise cultivated in the processing of various granites, we can also respond to high-precision processing of special materials.

Our Advantages

Various Granite Materials

Provide granite materials with different origins and performance, suitable for different industries and needs, such as Jinan black, India black. Utilizing the grinding technologies and know-how cultivated through all kinds of granite processing for tailor made products, we can also respond to high precision processing of special materials.

Large-scale & Special Processing

We have sufficient granite inventory and have achieved the processing of various types of granite, focusing on component columns, surface panels, and machine bases. We can also correspond to various special processing, including hole processing and slot processing.

Ultra-high Precision Processing

We have a factory dedicated to granite processing and assembly. It is equipped with constant temperature room (temp. 23 ± 1°C, humidity 50 ± 10%), constant temperature booth (temp. 23 ± 0.1°C) and abundant measuring equipment, and we can produce ultra-high precision products in submicron unit.

Characteristics of Granites

Low Static Electricity

The generation of static electricity is minute. It will not adsorb dust, ensuring that the electrical components assembled on the granite components will not malfunction or be disturbed.

No Effect from Scratches

Even if it gets scratched, it does not burr and maintains precision surface. To ensure that the flatness and roughness of the overall granite precision surface are maintained at a high-level.


Granite is naturally formed and has undergone tens of thousands of years of environmental changes on Earth, it can ensure accuracy maintained at a good level in later use.

Anti-vibration Characteristics

The physical characteristics of granite itself determine that it has anti vibration characteristics, ensure the precision accessories assembled on granite components have a good buffered carrier.

Thermal Conductivity

The thermal conductivity of granite is lower than that of metals and is not sensitive to changes in the external environment, so the precision surface of granite is stable.

Abrasion Resistance

The hardness of granite is much higher than that of metals, especially cast iron parts, and it has excellent abrasion resistance, which can ensure that granite components are not worn out after long-term use.
