Our main products are: cast iron inspection plate, dash plate, welded plate, T-slot mounting platform, boring and milling machine table, triangular standard platform, motor test platform, Pyrotechnics platform, floor boring machine table, Mg, Al light flat feet, flat feet flat iron bridge type flat feet, feet, rectangular device, machine dedicated point-foot, test square box, crossed square boxes, magnetic square box, magnetic V-frame, deflection tester, gear runout inspection instrument, machine test bars, machine adjustment horn, machine vibration horn, ladder horn, high horns, cast iron V-shaped, V-shaped steel frame, cast iron plate bending, sine, shaft card board or the Mouth retaining plate, smooth proofreading special ring, optical limit hole gauges, dash plate, cylindrical square, chrome jack, granite slab, flat feet, square box, parallel to the regulation, adjustable granite pillar, V-block, V-rack, granite table seat, etc. Tools can also order all kinds of non-standard measuring tool (users need paper drawings), and other precision measuring products are exported to the United States, Germany, South Korea and other countries by domestic and foreign customers. Cast iron is a versatile platform for a variety of uses in one set of cast iron platform. Can be used for marking, scraping, test, test, test, measurement, and other purposes. ???? Material: high-strength cast iron HT200-300, face hardness HB170-240, after two manual processing (annealing 600 degrees -700 degrees artificial and natural aging 2-3 years) so that the accuracy of the product stability, resistance good wear performance. Specifications: 200x200-3000x6000, (larger than this size can be assembled assembly platform used or made by the drawings). Accuracy: according to the national standard verification procedures, namely, 0,1,2,3 four grades. Compression Platform: is based on a standard platform, the thicker the table, put the ribs on the back platform based on the original strengthen again. Compression Platform Features: can withstand greater pressure, high stability, not deformed. 1. often used in large-scale assembly and commissioning of power machinery equipment; 2. cast iron surface compression platform with T-slot, so it is suitable for stationary power equipment. Should the need for a larger size when compression platform, the platform can also be assembled into large pieces of cast iron compression platform. Note the use of cast iron assembly platform: 1. Before use, the first installation and commissioning, to prevent damage to the compression plate Face; 2. Use the process should pay attention to moisture, corrosion, taking care not to put in too high compression platform and stored under low temperature environment; 3. After the cast iron compression platform is completed, it should be cleaned at the same time make rust-proof work. Life is generally cast iron compression platform is very long, as long as the correct way to use and store, precision compression platform face can keep using more than two years, when the lower accuracy can be restored by the debugger or scraping process. Cast iron compression platform made of high-strength cast iron HT200-300, then face hardness HB170-240. After two manual processing (annealing 600 degrees -700 degrees artificial and natural aging 2-3 years), precision cast iron compression platform becomes more stable, but also has better wear resistance. Cast compressive loading station Precision: According to the national standard verification procedures, namely, 0,1,2,3 four grades. ?? QQ: 2665803158 Tel: 0317-8258199 Mobile: 13463740861 Contact:?

Another company perennial foreign orders large CNC machining operations. I company of "quality development and credibility of survival" mode of operation. Open into a production and sales of aftermarket system, all customers to buy our products, if quality problems within six months, the implementation of the product "three guarantees"! Determined that the customer service center! Real life, working sense! Products a cast iron inspection plate (test platform) Alias: test platform, testing platform, platform inspection, inspection plate, cast iron measurement platform, cast iron measuring plate. Second, the cast iron inspection plate (test platform) uses: detecting machine parts flatness measurement reference, straightness and other geometric tolerances; can be used for grinding parts marking, installation of equipment and other purposes; test the mechanical parts flat, parallel, straightness tolerance and other forms of measurement reference. Third, cast iron inspection plate (test platform) Material: high-quality high strength gray cast iron HT200-250, face hardness HB170-240, cast after two artificial annealing 600 ℃ -700 ℃ or natural aging 2-3 years, completely removed stress, accuracy and stability, good wear resistance. Fourth, cast iron inspection plate (test platform) Specifications: 100 × 100-3000 × 6000 (mm), special specifications can be manufactured according to user needs. Five, cast iron inspection plate (test platform) Precision: According to the national standard verification procedures JJG117-91 execution, namely 0, 1, 2. Six, cast iron inspection plate (test platform) Surface treatment: Face using scraping process, tested with the coloring method to ensure the accuracy of the plane. Face is generally flat, can also be processed in accordance with the requirements such as long or round holes. Seven standard cast iron inspection plate (test platform) related parameters: eight, cast iron inspection plate (test platform) Packing: wooden packaging. Before packing by anti-rust treatment and proper packaging to prevent damage to the product due to poor packaging during transport. The plate was certified by, should be accompanied by a product certification; shall be the date of manufacture and serial number on the product certification. Nine, cast iron inspection plate (test platform) Technical requirements: 1, flat working surface may not have sand holes seriously affect the appearance and performance, the pores, cracks, slag, shrinkage, scratches, bumps, rust and other defects. 2, the casting surface of the plate should be cleared of sand and flat, painted solid. 3, the accuracy of the registration level is 0 -3 flat work surface, a diameter of less than 15mm of clearance holes allowing the same material clogged, its hardness should be 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, should be used to create high-quality fine flat gray cast iron or alloy material, its face hardness should 170-220HB. 5, flat working surface shall normally be by scraping process. Scraping of adopting three flat working surface, the maximum allowable value of the surface roughness Ra 5um. 6, flat working surface flatness tolerances specified in Table 2. 7, flat working surface using scraping process should be painted on the research test. After the research on the area of ??the contact point is displayed a predetermined ratio shown in Table 3: or according to a square area of ??25mm × 25mm a predetermined number of contact points are shown in Table 3, and should any of 25mm × 25mm between the contact points is not more than 5:00. Ten, cast iron inspection plate (test platform) use: 1, before use non-corrosive gas, anti-rust oil wash the face, and wipe clean with skim cotton, can be used. 2, the temperature change will make the measurement errors, should be used in a range of 20 ± 5 ℃. 3, when used with a spirit level to adjust the level so that uniform distribution of the pivot fulcrum. 4, when used carefully to prevent collisions. 5, after use wipe dry acidic anti-rust oil coating, waterproof paper cover, in a clean dry place. 6-week inspection period: the longest weekly inspection of one year. Cast iron is a versatile platform for a variety of uses in one set of cast iron platform. Can be used for marking, scraping, test, test, test, measurement, and other purposes.
