Granite With Threaded Inserts

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

The granite machine base is a high-precision structural component made from natural black granite, engineered for applications requiring superior dimensional stability, vibration damping, and corrosion resistance. It serves as a foundation base for a wide range of precision equipment, such as CNC machines, laser systems, coordinate measuring machines (CMM), and semiconductor equipment.

With excellent mechanical and thermal properties, the granite machine base provides long-term accuracy and reliability in demanding industrial environments.

Key Features and Advantages:

Excellent Dimensional Stability
Naturally aged granite with no internal stress ensures stable geometry and minimal deformation over time.

High Vibration Damping
Granite with threaded inserts effectively absorbs vibrations, making it ideal for high-precision equipment and sensitive measuring systems.

Corrosion and Rust Resistance
Granite with threaded inserts is resistant to humidity, chemicals, and oxidation, requiring no surface treatments or painting.

Custom Machining Options
Available with threaded inserts, positioning holes, T-slots, bushings, and assembly points to suit your machine design.

Non-Magnetic and Thermally Stable
Low thermal expansion coefficient and non-magnetic properties make it suitable for optical and electronic applications.
