Granite V-block
The granite V-block chiefly contains pyroxene, plagioclase, olivine, biotite, and magnetite. It is black in appearance, precise in structure. The billions of years of natural aging allow this vee block to possess uniform texture, good stability, high strength, and high hardness. Even under the condition of heavy loading, our granite measuring block still can maintain the high precision.
ApplicationThe granite V-block set can match with the surface plate for testing the concentricity of axles, and for precise scribing. Also, it can serve as the pad iron used for the accessories. This product is mainly suitable for the precise inspecting, measuring, or scribing in the laboratory, component manufacturing, and industrial machining operation.
This type of V-block is sold in pairs, and should be used in pairs.
