Granite parallel gauges are mainly used for parallelism inspection of mechanical equipment and can also be used as equal height cushion blocks. This parallel gauge is supplied in pairs and can be customized for processing according to user requirements. This product is made by manual precision grinding.
The parallel gauge material of granite is natural granite, with the main mineral components being escape stone, plagioclase, a small amount of olivine, biotite, and trace magnetite. It has a black color, precise structure, and has undergone billions of years of aging. Its texture is uniform, stable, strong, and hard, and it can maintain high precision under heavy loads. Suitable for industrial production and laboratory measurement work.
