The thermal deformation of gray cast iron is much lower than other materials. For example, the contact surface of the base and the upper surface of the vertical car must be manually scraped. If it is cast steel or wrought iron, it cannot be manually scraped.

Cast iron base plate, test bench plate is the large base plate of the test bench for testing the running-in, loading, vibration, and fatigue performance of the automobile, reducer, gearbox, motor and other scientific research institutes and production unit laboratories during the product bench test.

The cleaning process is to clean the casting from the mold after the casting of the cast iron platform is cooled to obtain a casting with no defects on the surface.

After the parts are processed by the equipment, the cast iron bending plate and other equipment shall be treated with rust prevention.

The wiring layout of the cast iron welding platform directly affects the complexity of flatness data processing and the accuracy of flatness error measurement.

The use of manual scraping on the cast iron scribing platform can ensure good flatness, good contact, and more contact points, and it has a certain hardened surface to enhance the wear resistance. Use a scraper to manually trim the surface shape and roughness of the workpiece, which is called scraping.
