Made from high-quality “Jinan Black” stone material through mechanical processing and hand precision grinding. It features high precision, no deformation, excellent stility, and a long service life, making it suitable for measurement work in machine shops and laboratories.
The main mineral components of “Jinan Black” granite are pyroxene,plagioclase, biotite, and trace amounts of magnetite. With a black color and a fine structure, it has undergone aging over hundreds of millions of years, resulting in a uniorm texture, excellent stability, high strength, and high hardness, allowing it to maintain high precision under heavy loads.
Advantages:
1. High precision, excellent stability, and resistance to on, ensuring measurement accuracy at room temperature.
2. Rust-proof, resistant to acids and alkalis, and requires no special maintenance.
3. Excellent wear resistance and long servlife.
4. Scratches or bumps on the working surface do not affect measurement precision.
5. No magnetization issues.
6. Smooth sliding during measurement with no stickin.

We can process various granite components for CMMs, such as bases, columns, crossbeams, and guides. We can also process granite bass, gantries, and slides for PCB drilling and milling machines, as well as engraving machines.
We process other custom-shaped products for customers.
The perfect combination of granite, metal.
