Detection platform uses: Suitable for inspection, precision measurement of the reference plane for measurement of mechanical testing machine basis, inspection, and dimensional accuracy for precision parts or disruptive behavior, and make precision crossed, is not in the machinery manufacturing lack of basic tools. 
 Detection platform Material: high strength cast iron HT20 - 40, face hardness HB170 - 240, after two manual processing (artificial annealing 600 ° - 700 ° and the natural aging 2 - 3 years) so that the accuracy of the product stability, wear resistance, the following products, materials and outside processing are the same except iron. 
 Accuracy testing platform: According to the implementation of the national standard verification procedures, namely 0,1,2,3 four levels.
