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

Granite bases are utilized for the mounting of mechanical, electronic, and optical gaging systems. Numerous laboratories specifically depend on granite bases for precise measurement and inspection. Every measurement relies on an accurate surface reference from which dimensions are derived, and granite plates provide the ideal foundation for gaging surfaces and ensuring accurate height measurements. Another reason granite is regarded as the most preferred material for surface plates is its low sensitivity to temperature fluctuations coupled with a hard surface.
However, over time, these surface plates may experience wear that hinders their ability to produce accurate measurements. Therefore, it is essential to maintain them properly and calibrate them regularly.
Different types of granite exhibit varying levels of wear; thus, it is crucial to select granite materials with excellent physical properties. UNPARALLELED® has extensively tested numerous varieties of granite and has chosen high-quality black granite for the manufacturing of precision granite bases.
UNPARALLELED® is synonymous with manufacturers specializing in high-end precision machine beds. The company can fabricate advanced machine beds as well as components for high-end precision machining tools. If your precision machinery does not incorporate UNPARALLELED mechanical beds, it likely does not qualify as high-end precision equipment.
UNPARALLELED® can manufacture a diverse range of precision granite components tailored to customers' specific requirements. If you need it, we can produce it!
All granite machinery parts are supported by ISO 9001, ISO 45001, ISO 14001 certifications along with CE Certification.
