Jiang Su Hongsheng Electrical Equipment Co., specializing in the production of cast iron, marble, granite slab, horn, square box, V-frame, measuring tool, Tel 15932730800 contact Miss website http://gaoweihong1688.cn.alibaba.com flat feet flat feet into test flat feet, parallel-foot, bridge type flat feet, angle-foot, granite-foot, marble flat feet, flat feet foot granite shaped gauge with accurate plane. In coloring for flat feet, indicating a long table method test platform rails, etc., it is also commonly used in light-gap method to test the edge of the right angle of the workpiece. Flat feet generally manufactured with high-quality cast, rectangular flat feet have made bearing steel or granite. Face flat feet may not have a serious impact on the appearance and performance of sand holes, pores, cracks, slag, shrinkage, scratches, bumps, rust and other defects. Flat feet should be used for manufacturing high-quality fine gray cast iron or alloy cast iron and other materials, its face hardness should be 170 ~ 220HB. Advantages of flat feet: flat feet with high-quality "Jinan Green" stone grinding by machining and hand made. Black gloss, structural precision, even texture, good stability, high strength, high stiffness, flat feet can be maintained under heavy duty and general temperature accuracy, and has no rust, acid, wear resistance, is not magnetized, What are the advantages of the same type of characteristics are flat feet? Flat feet in geometric measurement, using simulation to reflect the reference line, the current use of flat feet, more cast iron flat feet flat foot and rocks. Cast iron flat feet by scraping method to process measuring surface, it can be stored measuring surface oils and contain gray quiet, steady increase in the benchmark used, reliability. Rock square feet with an abrasion resistant, stable and easier to use advantages. Straightness measuring surface is flat feet flat foot to characterize the quality of the main precision index. The flat-face tape measure straightness tolerance allowable value to determine the size of the flat-foot level of accuracy. Press square feet of manufacturing accuracy level, the choice of flat feet, is conducive to the process of unity and precision equipment manufacturing precision measuring instrument series; help unify measuring tolerances; improve product manufacturing, the use of precision.
