Cast iron special flat plate

When users choose a dedicated platform (dedicated tablet), they can choose the appropriate specifications based on the platform's own load-bearing capacity and requirements. Here is an introduction to our company's dedicated platform (dedicated tablet):
Specialized platform (specialized tablet) specifications: 1000 × 750-3000 × 6000 (mm), special specifications can be manufactured according to user needs, and welding platforms larger than this specification can be spliced.
Specialized Platform (Specialized Tablet) Product Nicknames: Welding Plate, Welding Platform, Cast Iron Welding Plate, Cast Iron Welding Platform, T-slot Welding Platform, T-slot Welding Plate, Basic Welding Plate, Basic Welding Platform, Welding Workbench.
Purpose of dedicated platform (dedicated tablet): Used as a special reference measuring tool for mechanical or machine tool marking and inspection. We need to provide customized drawings. The production cycle is 20 working days.
The accuracy of the dedicated platform (dedicated tablet): According to the national standard metrological verification regulation JJG117-91, it is divided into three levels: Level 1, Level 2, and Level 3.
Special Platform (Special Tablet) Material: High quality high-strength gray cast iron HT200-250, with a working face hardness of HB170-240. The casting has undergone two artificial annealing processes at 600 ℃ -700 ℃ or natural aging for 2-3 years, completely removing internal stress, with stable accuracy and good wear resistance.
Specialized platform (specialized tablet) style: The product is made of reinforced rib plate with a reasonable design structure.
Specialized platform (specialized tablet) packaging: wooden packaging. Before packaging, the product should be treated with rust prevention and properly packaged to avoid damage during transportation due to poor packaging. After passing the inspection, the tablet should be accompanied by a product certificate of conformity; The product certificate should include the date of manufacture and product serial number.
Technical requirements for cast iron special platform (special flat plate):
1. The flat working surface shall not have defects such as sand holes, air holes, cracks, slag inclusions, shrinkage porosity, scratches, bumps, rust spots, etc. that seriously affect the appearance and performance.
2. The casting surface of the flat plate should be cleaned of sand and leveled, and painted firmly.
3. On flat working surfaces with precision registration levels of 0-3, sand holes with a diameter less than 15mm are allowed to be blocked with the same material, and their hardness should be lower than that of the surrounding materials. The number of sand holes blocked in the working face should not exceed 4, and the spacing between sand holes should not be less than 80mm.
4. The flat plate should be made of high-quality and fine gray cast iron or alloy materials, and its working surface hardness should be 170-220HB.
5. Flat working surfaces should usually use scraping technology. The maximum allowable surface roughness Ra for a 3-level flat working surface processed by scraping is 5um.
6. The flatness tolerance of the flat working surface is specified in Table 2.
7. The flat working surface should undergo color matching inspection when using scraping technology. The ratio of the contact point area displayed after research is specified in Table 3, or the number of contact points in a 25mm x 25mm square area is specified in Table 3, and the number of contact points in any 25mm x 25mm area should not exceed 5 points.
Instructions for using the dedicated platform (dedicated tablet):
1. Before use, use non corrosive gasoline to clean the anti rust oil on the working surface, and wipe it clean with degreased cotton yarn before use.
2. Temperature changes can cause measurement errors and should be used within the range of 20 ± 5 ℃.
3. Adjust the level to horizontal when using, so that the support points are evenly distributed on each support point.
4. Be careful and prevent collisions when using.
5. After use, wipe clean, apply anhydrous acidic anti rust oil, cover with moisture-proof paper, and store in a clean and dry place.
6. Weekly inspection period: The longest weekly inspection period is one year.
