Bridge type flat feet with shading, indicating Examine the table flatness flat, long rails, etc., to the optical gap of the workpiece edge straightness inspection. Face-foot bridge - not have a serious impact on the appearance and performance of sand holes and pores, cracks, slag, shrinkage, scratches, bumps, rust and other defects. Bridge type flat feet: Face with precision grinding and scraping process, mainly for the machine check the irregularities and non-straightness test. Also applies to equipment installation and maintenance. Bridge type flat feet are used to measure the workpiece straightness and flatness measuring, temperature (20 ± 5) ℃. Face-foot bridge - using scraping process. Most flat feet of gray cast iron or alloy cast iron and other materials, rectangular flat foot is also useful for the manufacture of bearing steel or granite. Bridge type flat feet face hardness should be 170 ~ 220HB. Bridge type flat feet by JB / T7977-99 standards for manufacturing, material HT250, face scraping or precision grinding technology research for the machine inspection and testing roughness degree two working faces are not straight with the block gauge, micrometer, levels and other equipment testing, different heights, two parallel rails and horizontal rails are not connected, and can be used with rectangular device, measuring the verticality of the two parts of the test can not be tested using only rectangular device, and also applies to equipment installation and inspection. Advantages bridge type flat feet: flat feet using machining and grinding is made by hand. Structural precision, even texture, good stability, high hardness, flat feet accuracy can be maintained under heavy duty and general temperature, has no rust, acid, wear resistance, is not magnetized, variations and other advantages. Foot bridge - Size: 400mm * 100mm * 40mm ---- 3000mm * 200mm * 80mm (larger than the above specifications may be required when manufacture) More information, please visit http://www.hbzbzg.com
