Coordinate platform use: testing for a variety of coordinate measurement, machine mechanical testing benchmarks; check the dimensional accuracy of parts or the shape of deviation of the surface with a coordinate line, easy to coordinate measurement coordinate platform, three coordinates of flat plate material: high-strength cast iron HT200-300 face hardness of HB170-240, after two manual processing (annealing 600 degrees -700 degrees artificial and natural aging 2-3 years) use of the product accuracy and stability, wear resistance good. Coordinate platform coordinate plate size: 100mm × 100mm-3000mm × 6000mm, (larger than this specification or drawings can be assembled using customized.) Coordinate platform, coordinate precision plate: the standard verification procedures according to national implementation , respectively, four grades 0,1,2,3 installed on the raised flat horizontal plate, the load being evenly distributed on the fulcrum of environmental temperature (20 ± 5) ℃. should be used to avoid vibration.
