1. Thickness requirements: Mainly include the thickness of the working surface on the platform, the thickness and height of the side wall, and the thickness, height and density of the bottom gluten plate.

 

2. Material requirements: cast iron HT200-300, hardness: HB170-240.

 

3. Manual annealing: After 600-700 degrees high temperature annealing and aging treatment in the tempering kiln.

 

4. Trachoma and stomata: Stomata and trachoma are not allowed on the level 0 and 1 platforms, and the 2 and 3 can be filled with solids of the same material as the platform. Note: The hardness of the filler is lower than the hardness of the platform itself.

5. Scraping process: Manual scraping is an important process in the processing of cast iron platforms. It determines the flatness error of the cast iron bed plates and the number of contact points on the working surface. The level 0 board platform shall have no less than 25 points within the range of 25mm square on each side; the level 1 platform shall not less than 20 points within the range of 25mm square on each side; the level 2 board platform shall be 25mm square on each side No less than 16 points within the range; Level 3 flat platform is not less than 12 points within a range of 25mm square on each side. After shoveling, the four edges of the platform are blunt.

 

6. Sand cleaning and painting: The bottom surface of the platform is sanded, clean and sprayed with anti-rust paint. The sides should be leveled before painting.

 

7. Packaging requirements: mainly wood packaging, try to use thick wood to cover the working surface of the platform, and always make fully enclosed packaging. Anti-rust measures should be taken for the working surface of the platform before packaging.

 

8. Transportation requirements. After loading on the platform, check whether there is any dangling. Do not stack the platform too high to avoid squeezing and deformation.

 

9. Accessories selection: Mainly the bracket selection. The bracket materials are square steel and angle iron with a wall thickness of 1.5-2mm. The welding density and structure must be reasonable, and the adjustment bolts must be rotated smoothly.

 

10. Installation and debugging: Generally, use a frame leveler to level it first, and then perform a flatness error measurement with an optical combined image level or electronic combined image level. If there is any problem, you can ask the platform manufacturer to scrape on site.

 

11. Correct use: The cast iron bed plate can be used after the commissioning is completed. The room temperature should be controlled at 20±5℃. The workpiece should be handled gently to detect the workpiece on the table. Do not use a single area. Try to use the entire cast iron bed plate evenly.
