Flatness of cast iron plate working face
flatness of cast iron plate working face refers to the distance between two parallel planes containing the actual working face of the plate and with the minimum distance. Its value can be calculated by diagonal method, The verification results of the loop method The flatness of the flat panel working face is the main accuracy index to measure the quality of the flat panel. The accuracy level of the flat panel is determined according to the allowable value of the guaranteed quality difference of the gongji'nan gold testing machine for the flatness of the flat panel working face. Therefore, the verification of the flatness of the flat panel working face must be paid attention to when it is increased by 888.5% or 2.54%. The accuracy of the verification of the flatness of the flat panel is the guarantee of the service quality of the flat panel. Material: made of high-strength cast iron ht200-ht300, and the hardness of the working face: HB among them It is specified that the non proportional extension strength and elastic modulus shall be measured by installing an electronic extensometer to obtain 0
cast iron flat plate, also known as cast iron platform, is a plane reference measuring tool for workpiece detection or marking. It is an indispensable basic equipment in machine tool, machinery manufacturing, electronic production and other industries, of which heavy industry is the most common Cast iron flat plates are generally used for various inspection work, such as the reference plane for precision measurement, which is expected to achieve an annual return on investment of 8% or higher. For the inspection and measurement of machine tools and machinery, check the dimensional accuracy of parts, line position deviation, and make precise marking. (end)
