Cast iron flat plate, also known as cast iron platform, is a flat reference measuring tool used for workpiece inspection or scribing. It is an indispensable basic equipment for machine tools, machinery manufacturing, electronics production and other industries. Among them, heavy industry is the most common. Cast iron flat plates are generally used for various inspection tasks, such as reference planes for precision measurement, inspection and measurement of various machine tools, inspection of dimensional accuracy of parts, deviations in position, and making precise scribes. Cast iron flat plates are also an indispensable basic tool in mechanical manufacturing. Botou Hengxun Machine Tool Casting and Measuring Tool Co., Ltd. is located in Botou City, south of Tianjin. It is a professional company producing tools and measuring tools. Our company mainly produces all kinds of adjusting, marking flat plates, shockproof machine mattress irons, jacks, and can also customize various models of machine mattress irons according to customer needs. The measuring tool series includes flat ruler, square box, true square ruler, bent plate, V-shaped frame (iron), yaw checker, "00" grade rock (marble) flat plate, measuring tool and so on.
The technical requirements for the design of gravity casting of aluminum alloys are generally designed according to the "People's Republic of China Machinery Industry Standard" JB / T 7974-2000, and the flat plates manufactured according to the national GB4986-85 standard have 00, 0, 1, 2, 3, grade and precision planing , The flat plate is made of ribbed and box type, and the working surface is rectangular, square or round. The working surface adopts a scraping process, and the working surface can process V-shaped, T-shaped, U-shaped grooves, round holes, and long holes. Aluminum alloy liquid extrusion .


The flatness of the working surface of a cast iron flat plate refers to the distance between two parallel planes where the actual working surface of the aluminum alloy is hydraulically squeezed to contain the flat plate and the distance is the smallest. "Get it. The flatness of the working surface of the flat plate is the main accuracy index for measuring the quality of the flat plate. The accuracy level of the flat surface is determined according to the tolerance of the flatness of the flat working surface. Therefore, the verification of the flatness of the flat working surface must be emphasized. The accuracy of the flatness test of the flat plate is the guarantee of the quality of the flat plate. Material: Made of high-strength cast iron HT200-HT300, working surface hardness: HB170-240.
