Cast iron bending: by GB6092 - 85 standards for manufacturing, materials HT200-HT300, face scraping process used for the detection of parts in the clamping and machining. 
 Cast iron bending: for inspection of the workpiece 90 ° angle, test equipment repair parts and components related to the surface of the perpendicular degree, also commonly used in the bench marking. Can be used in testing, installation, machine mechanical vertical checks and checks on the cast iron plate in the vertical parts, precision machinery and instruments for testing perpendicularity between the machine and check. 
 Note: Do not wet bending, corrosion, high and low temperature environments and storage. Used to conduct the bending of the installation, then, the bending of the face wipe clean, no problem in identifying the circumstances under bending. 
 Cast iron bending accuracy: 1, 2, 3.
