High Precision Jinan Black Granite Machinery Components for Metrology Equipment

High Precision Jinan Black Granite Machinery Components for Metrology Equipment

We specialize in manufacturing custom high precision granite machinery components crafted from premium natural Jinan black granite. All our granite workpieces undergo strict CNC mechanical processing combined with manual fine grinding to achieve ultra-tight tolerance requirements.

Our Jinan black granite parts feature an elegant black luster, compact and uniform internal structure, exceptional structural stability, high mechanical strength and superior hardness.

Under heavy load conditions and normal ambient temperature, these granite components can consistently retain ultra-high geometric precision. Unlike metal castings, natural granite is rust-proof, acid and alkali resistant, wear-resistant and non-magnetizable, making it an ideal base material for precision equipment.

Advantages of Jinan Black Granite Components

1. The raw granite material has experienced long-term natural aging. Its internal tissue structure is evenly distributed with an extremely low thermal expansion coefficient. Internal stress inside the stone has been fully released, so the finished granite workpiece delivers outstanding long-term precision stability.
2. Excellent rigidity, high Mohs hardness and remarkable wear resistance. It can withstand repeated friction and long-term continuous operation without easy deformation.
3. Resistant to acid and alkali corrosion and completely rust-free. No lubricating oil is required for daily operation, which greatly simplifies maintenance work and extends the service life of your precision equipment.
4. The surface is not easy to scratch. It is less dependent on strict constant-temperature workshops and can maintain reliable measurement accuracy under normal room temperature environments.
5. Non-magnetized property. When used for measurement applications, the sliding movement runs smoothly without binding or tight friction. It is not affected by ambient humidity, and maintains excellent flatness over years of use.

Application Scenarios：CMM, measuring machine, machine base etc，Our precision granite machinery components are widely used for coordinate measuring machine (CMM) bases, optical inspection platforms, machine tool beds, granite straight edges, granite squares, precision fixture bases and other metrology & automation equipment. We support custom sizes and tolerance requirements according to your technical drawings.
