Use of cast iron bending: bending special tools for machine tools, machinery equipment and spare parts vertical test, install processing position, crossed the machinery industry and other important measurement tools, and supporting the table in use for processing. It features high accuracy, stability and easy maintenance. Size: 300 × 200 × 250 ~ 700 × 400 × 500 (mm) accuracy: 0, 1, 2, 3 for the inspection of the workpiece bending angle of 90 °, maintenance, equipment parts and components related to the surface of each test vertical, but also commonly used in the testing, installation, inspection machine vertical machinery, and workpiece in the vertical plate check degrees. 
 Cast iron face plate bending process by scraping for 90 ° angle of the workpiece inspection, maintenance equipment between the surface of the test parts in the vertical, and often in bench marking and inspection and machining of parts installed in folder. Cast iron plate bending can check the verticality of the workpiece for precision machinery and equipment, inspection and machine inspection between the non-vertical, widely used in industrial measurement. 
 Cast iron vertical bending test for products, are rectangular device class. Bending cast iron manufactured according to national standards, the material is HT200-HT300. Method for manufacture of cast iron bending mostly used in precision casting casting process. With the progress of science, cast into the factory of mass production, the previous technology could not meet production requirements, resin sand molding made the application and development of core technology, the quality of foundry sand has put forward higher requirements. Foundry sand shall meet the following requirements: a high degree of purity and cleanliness, to silica sand, for example, iron sand requires more than 90% SiO2 content, the larger steel casting requires more than 97% SiO2 content; high fire and thermal stability; appropriate particle shape and particle composition; difficult to be liquid metal wetting. The shape of particle shape of sand casting are generally 3. Round Sand: particles are round or near round, smooth surface, there are no outstanding angular; polygonal sand: particles into a polygonal, and mostly obtuse; cusp-shaped sand particles into the cusp-shaped, and mostly acute angle. Foundry sand particles are generally angular shape factor (the actual surface area of ??sand / sand theoretical specific surface area) to represent. Bending according to GB6092-85 standards for manufacturing, face research process by scraping, the material is HT200-HT300. Technical parameters, including bending the carrying bending, bending the length and breadth, the surface accuracy of bending, bending plate weight, bending plate material requirements. 
 The accuracy of cast iron plate bending can be divided into 000, 00, 0, 1, 2, Level 3.
