Navistar cast parallel to the flat foot: by JB/T7977-99 standards for manufacturing, materials, HT250, face using scraping or grinding precision, for machine inspection and testing roughness degree two face is not straight with the gauge block , micrometer, level meter and other equipment inspection, different heights, two parallel rails and horizontal rails are not connected, and can scale with the right angle, right angle foot test can only test two parts of the verticality of the gauge, also applies to equipment installation and inspection. 
 Navistar cast iron is a precise parallel flat feet flat foot-shaped gauge (see Figure). Square feet used to shading indicate that the table method test plate, the flatness of long rails, etc., are also commonly used in light-gap method to test the straightness of the workpiece edge. Flat feet is generally of high quality cast iron, rectangular flat feet are also useful for bearings made of steel or granite. 
 Navistar company was founded in 1990, has over 10,000 square meters of first-class workshop, an area of ??100 acres, is a design, manufacturing, processing, marketing, maintenance as one of the professional modern company. Annual production of 20,000 tons of various castings, the main products: various specifications according to national standard production cast iron inspection plate, dash plate, welding platform, parallel to the flat-foot, square box, right angle foot, V-iron, deflection tester, testing machine rod, adjust the horn machine, machine tool vibration horn, granite measuring tools such as measuring tools. In order to facilitate the user, but also customized according to customer request processing non-standard measuring tools, to undertake real-type (LFC), resin sand casting process, including steam turbine plant pad boxes, machine tool plant bed, column, beam, bench , machinery and equipment manufacturing various types of cast iron base and gantry milling machine, planer, floor boring machine, vertical lathes and other machine tool equipment products manufacturing machine ... ... reasonable, stable structure, high precision, wear-resistant, long life, material are using high grade cast iron HT200-300, Platform (board) hardness of HB160-210, flat feet and other products to HB170-240
