The use of cast iron platform: for a variety of inspection, precision measurement of the base plane; benchmark for measuring mechanical testing machine; check the dimensional accuracy of parts or the shape and position deviations, and as close crossed, in the machinery manufacturing is also indispensable the basic tools. 
 Surface quality inspection platform, cast iron: test with a hair coloring. 0 1 plate on each side of the range of 25 mm square of not less than 25 points, 2 less than 20 points, three less than 12 points. 
 Cast iron platform specifications: 200 × 200-2000 × 4000mm (special size according to the demand side or two sides agreed to make drawings production and processing) 
 Precision cast iron platform: According to the implementation of the national standard verification procedures, namely, 0,1,2,3-level four levels. 
 Cast iron platform Material: high strength cast iron HT200-300. Face hardness: HB170-240. 

 Mounting plate (platform) Use: used in machinery and equipment, assembly and commissioning, the surface with a T-shaped slot, can be fixed machinery and equipment, requiring a larger assembly platform for assembly use. 
 Mounting plate (platform) Material: high strength cast iron HT200-300, face hardness of HB170-240, after two manual processing (annealing 600 degrees -700 degrees of artificial and natural aged 2-3 years) using the precision and stability of the product, good wear resistance. Precision: According to the implementation of the national standard verification procedures, namely, 0,1,2,3 four grades. 
 Mounting plate (platform) specifications: 1000 × 1000-2000 × 4000, (the products are produced according to customer drawings or agreed upon production and processing process, users can request the size and weight of the production). 

 Test plate Application: all kinds of inspection, precision measurement of the datum plane; mechanical testing benchmarks for machine tools; check the dimensional accuracy of parts or of the form deviations, and for close crossed, in the machinery manufacturing is indispensable basic tools. 
 Test plate surface quality inspection: The hair coloring test. 0 1 plate on each side of the range of 25 mm square of not less than 25 points, 2 less than 20 points, three less than 12 points. 
 Flat test accuracy: the standard verification procedures according to national implementation, namely 0,1,2,3-level four levels. 
 Test plate size: 200 × 200-2000 × 4000 (special specification according to the demand side or two sides agreed to make drawings production and processing). 
 Test plate material: from high-strength cast iron HT200-HT300 manufacturing, face hardness: HB170-240.
