This pair of granite V-blocks is a professional clamping and positioning measuring tool for shaft parts. It is made of natural high-density granite, which has the characteristics of high hardness, corrosion resistance, and stable dimensional accuracy. It is mainly used to fix cylindrical shaft parts for concentricity, parallelism, and length measurement, solving the problem of unstable clamping and inaccurate measurement of traditional steel V-blocks in high-precision processing scenarios. It is widely used in bearing processing, hardware machining, and instrument calibration industries.
