OEM granite measurement tools

Precision Granite Surface Plates

Engineered as the ultimate reference plane for precision measurement and layout tasks.Our granite plates offer unparalleled stability and flatness due to the inherent properties of dense black granite.They provide a wear-resistant,non-magnetic,and corrosion-resistant surface ideal for metrology labs and production floors.

Granite Straightedges and Squares

Master straightness and squareness with tools crafted from high-quality granite.These instruments feature exceptional thermal stability and minimal coefficient of expansion,ensuring measurement integrity across varying environmental conditions.The precision-ground edges and surfaces guarantee reliable accuracy for inspection and setup applications.

Granite Surface Profiles

Designed for checking the flatness and straightness of large machine ways and surfaces.Their robust granite construction resists deflection,providing a consistent and reliable reference standard.The balanced design allows for easy handling and stable placement.

Granite Sine Bars&Accessories

For precise angle measurement and setting,our granite sine bars offer superior stability and accuracy.Paired with granite accessory sets,they form a complete solution for angular measurement tasks in controlled environments,free from the risk of rust or magnetic interference.

Key Advantages:

Exceptional Stability&Accuracy:Granite's natural damping characteristics and dimensional stability provide a consistently reliable base.

Long-Term Durability:Highly resistant to wear,corrosion,and scratches,ensuring a long service life with minimal maintenance.

Thermal Neutrality:Low coefficient of thermal expansion minimizes measurement drift caused by temperature changes.

Universal Application:Suitable for a wide range of industries including aerospace,automotive,precision manufacturing,and quality control laboratories.

All products are precision manufactured and inspected to meet stringent flatness,straightness,and squareness tolerances,serving as the foundational standard for critical measurement processes.
