What are the processing techniques for cast iron platforms

The manual scraping and grinding process for cast iron platforms is a traditional metal processing technique and belongs to a type of precision machining. Scraping grinding is a manual operation that uses a scraper, its quasi surface, measuring tools, and display agents to grind points while measuring and scraping, so that the workpiece reaches the precision specified in the process. Scraping grinding technology can also reduce the surface roughness value, improve contact accuracy and geometric accuracy, thereby improving the overall fit stiffness, lubrication performance, mechanical efficiency, and service life of the machine tool and flatness. Traditional cast iron platforms calculate accuracy by counting points, but with the development of industry, modern production requires production efficiency, and counting processes are too time-consuming. Therefore, now they are not counted, and electronic level or composite level is used to detect the overall flatness of the cast iron platform. The processing technology of cast iron platforms includes not only manual scraping and grinding, but also precision planing, manual grinding, CNC machining, etc. Among them, the surface of cast iron platforms with manual grinding and CNC machining is smooth, while those with manual scraping and grinding have knife marks on them, and those with precision planing have dots on them.
