Cast iron plate cast iron platform platform first large cast iron table measuring the cheapest industry

Experimental platform (test plate) Uses: Iron is mainly used to produce a variety of mechanical tests and other products, stitching and other purposes, the above can have holes and T-slots for fixing the workpiece, and clean machining also Experiments can be designed into a flat platform (test plate) Material: high-strength cast HT200-300 face hardness HB170-240, after two manual processing (annealing 600 degrees -700 degrees artificial and natural aged 2--3 years) use this. the accuracy of product stability, good wear resistance test platform (test plate) Specification: 100 * 100-3000 * 6000, (special specifications according to the demand side, drawing production.) experimental platform (test plate) Accuracy: according to the national standard verification procedures execution, namely, 0,1,2,3 four grades of surface quality plate and the coloring method test. Tablet Specifications failed full column, press approximate dimensions testing requirements. 0, 1 plate on each side of 25mm less than 25 points within the range of the square: two plate on each side of not less than 20 points within the range of 25mm square: less than 12 points in three plate on each side of 25mm square range of assurance laboratory. safety and quality room platform, the company introduced from the production process to detect a completion. Each product to ensure the safety of every step. Experimental platform technical requirements, the platform may not have a serious impact on Face the appearance and performance of sand holes, the pores, cracks, slag, shrinkage, scratches, bumps, rust and other defects. 2, the casting surface of the platform should be clear sand and smooth, painted solid. 3, precision registered as 0 - Class 3 flat work surface, the hole diameter of less than 15mm of sand allows the same material clogging hardness less than the hardness of the surrounding material. Face clogged sand hole should be limited to four, and the spacing between the holes of sand should not be less than 80mm. 4, the platform should be used to create high-quality fine gray cast iron or alloy material, its face hardness should 170-220HB. 5, the platform should normally face in shaving technology. Processing adopting scraping Face plate 3, the maximum allowable value of the surface roughness Ra 5um. 6, the flatness of the platform face 2 tolerances specified in Table. 7, the platform working surface using scraping process should be painted on the research test. After the contact point of the research area ratio shown in Table 3 are predetermined: 25mm × 25mm square or press the contact area of ??a predetermined number of points are shown in Table 3, and should any of 25mm × 25mm between the contact point of not more than 5:00. In case of disputes, according to the ratio of the area of ??the contact point for the assessment basis.
