The laboratory-grade granite V-blocks produced by our company have achieved full-chain optimization in materials, craftsmanship, precision, and stability, addressing the three coues of datum drift, environmental interference, and wear deformation in precision measurement. They have become indispensable datum tools in high-end manufacturing and scientific research, providing a reliable guarantee for the qualit of critical components.<\/p>\n

Used for measuring coaxiality, roundness, symmetry, and runout of rotary parts. Generally supplied in pairs; please inquire separately for single-piece ers.
