= = Marble parallelism gauge is mainly used to detect parallelism and perpendicularity. The main mineral components of granite are plagioclase, a small amount of olivine, biotite, and a trace of magnetite. The black color structure is precise. After hundreds of millions of years of aging, the texture is uniform. It has good stability, high strength, and high hardness. It can maintain high resistance under heavy load. Accuracy. Suitable for industrial production and laboratory measurement work.
= = Marble parallel gauges, also known as granite parallel gauges, are produced in pairs and can replace equal-height pads. They are mainly used to measure the parallelism of workpieces. Marble parallel gauges require straightness and parallelism to comply with -. The marble parallel gauge is a high-precision benchmark measuring tool and is an ideal datum surface for the inspection of instruments, precision tools, and mechanical parts
