Quality Inspection:
1. The working surface should be free of rust, scratches, bumps and other appearance defects affecting the use.
2. There should be no casting defects such as sand holes, air holes, cracks, slag inclusion and shrinkage on the working surface. Various casting surfaces should be clear of molding sand, and the surface should be flat and painted firmly. The edges should be blunt. On flat work surfaces with accuracy levels lower than "00", sand holes with a diameter of less than 15mm are allowed to be blocked with the same material, and their hardness should be lower than the hardness of the surrounding materials. There should be no more than four places blocked on the working surface, and the distance between them should not be less than 80mm.
3. The opposite two sides should be provided with threaded holes or cylindrical holes for lifting facilities such as handles and rings. When designing the lifting position, consideration should be given to minimizing changes due to lifting.
4. According to the user's requirements, after setting threaded holes or grooves on the working surface of the board, these parts should not have a convex phenomenon higher than the working surface.
5. It should be made of high-quality fine-grained gray cast iron or alloy cast iron.
6. The hardness of the working surface should be HB 170-220.
7. The working surface should adopt the scraping process. For the "3" level flat working surface, the planing process can also be used. The surface roughness of the planed working surface should be less than 5um according to the arithmetic mean deviation of the contour.
8. It should undergo stability treatment and demagnetization.

Flat grinding of cast iron :
In the early days, people used three platforms to match each other to produce a true flat plane. A skilled and patient master of stone can make three 90-degree rotations without the aid of any measuring instruments, and can produce unbelievable levels of true flatness.


Flatness of cast iron platform :
Can be divided into laboratory level (Reference), calibration level (Master), tool room level (Working) three levels
1.AA grade: its flatness = 1 + 1.6D 2 (D is the diagonal length or diameter of the platform). It is used for highly precise measurement, and it is often used in the laboratory.

2. Grade A: its flatness is twice the error of AA grade, and it is often used for the inspection of precision measuring tools in the tool inspection room.
3. Grade B: Its flatness is four times the error of AA grade. It is often used in tool inspection room or on-site inspection of measuring tools or marking.

Notes on the use of cast iron platforms :
Before use, it must be installed and debugged. Then, wipe the working surface of the plate clean and use it without any problems. During use, care must be taken to avoid excessive collision between the workpiece and the working surface of the plate to prevent damage to the working surface of the plate; the weight of the workpiece is even worse. Exceeding the rated load of the plate, otherwise the work quality will be reduced, the structure of the plate may be damaged, and the plate may even be deformed and damaged, making it unusable.
