 Navistar iron scraping platform (flat) Accuracy: standard verification procedures according to national implementation, namely 0,1,2,3 grade four level. 
 Navistar iron scraping platform (flat) Material: high-strength cast iron HT200-300. 
 Navistar iron scraping platform (flat) face hardness: HB170-240. 
 Navistar iron scraping platform (flat) surface quality inspection: The coloring hair test, 0 1 flat on each side of 25 mm square range of not less than 25 points, two less than 20 points, 3 less than 12 points. 
 Navistar iron scraping platform (panel) to ensure the accurate shape, size, high accuracy and surface finish, which in the grinding process there is a tablet containing a silicon carbide abrasive scrub on the form, in this form of research with the main tool is essential. The study called embedded with sand flat, flat ground with a homogeneous, compact structure, no blisters holes, no loose, etc., is easy on the sand, the sand evenly distributed wealth, strong sand embedded in a solid cutting surface smooth, glossy, was blue, good wear resistance. Scraping platform use: Suitable for a variety of inspection, precision measurement of the reference plane; testing benchmarks for machine tools; check the dimensional accuracy of parts or the shape of deviation, and as close crossed, in the machinery is not to stay in lack of basic tools. 
 Navistar iron scraping platform (flat) features: 
 1 simple, fast on the sand, embedded in sand and quantity, is still very easy to use, on the same sand, polished, the finish improved significantly. 
 2 easy to get a higher amount of block needed to study together and finish of the workpiece glossy green light. 
 3 flat and durable, and durable enough to cut, sand slight lead after the cutting is still a good, smooth feel when to push research.
