铸铁平板是用于精密零件的测量和检验！平台的表面技术要求。

1、工作表面不应有锈迹、划痕、碰伤及其他影响使用的外观缺陷。 

2、工作表面不应有砂孔、气孔、裂纹、夹渣及缩松等铸造缺陷。各种铸造表面应清除型砂、且表面平整，涂漆牢固。各棱边应修钝。在精度等级低于“00”级的平板工作面上，对于直径小于15mm的砂孔允许用相同的材料堵塞，其硬度应低于周围材料的硬度。在工作面上堵塞的部位应不多于四处，其相互之间的距离应不小于80mm。 

3、相对两个侧面上，应设置有安装手柄、吊环等吊装设施的螺纹孔或圆柱孔。设计吊装位置时应考虑尽量减少因吊装而引起的变动。

4、根据用户要求，在板工作面上设置螺纹孔或沟槽后，这些部位不应出现高于工作面的凸起现象。 

5、应采用优质细颗料的灰口铸铁或合金铸铁制造。 

6、工作面的硬度应为HB 170-220。 

7、工作面应采用刮削工艺，对于“3”级平板工作面也可以采用刨削工艺，刨削工作表面的表面粗糙度按轮廓算术平均偏差Ra值应不大于5um

8、应经过稳定性处理和去磁。 
平 面 度：可分实验室级(Reference)、校验级(Master)、工 具室级(Working) 三级 
平面研磨：平台在很早的时候,人们利用三块平台相互匹配以产生真平平面。一个熟练而 又有耐心的 磨石师傅可以不藉助任何量测仪器,而仅利用三平台相互匹配的 方式,做多次90度之旋转, 即可产生令人难以相信的真平程度。 

平面度： 

1.AA级:其平面度(μm)= 1+1.6D2 (D为平台对角线长或直径),用於高度精密 之测定之用, 常用於实验室。 

2. A级:其平面度为AA级之两倍误差,常用於工具检验室作精密量具之检验之用。

3. B级:其平面度为AA级之四倍误差,常用於工具检验室或在现场检验量具或划线之用。

Cast iron plates are used for the measurement and inspection of precision parts! Surface technical requirements for the platform.
1. The working surface should be free of rust, scratches, bumps and other appearance defects that affect the use.
2. There should be no casting defects such as sand holes, pores, cracks, slag inclusions and shrinkage on the working surface. All kinds of casting surfaces should be cleaned of sand, and the surface is flat and the paint is firm. Each edge should be blunt. For flat work surfaces with a precision class lower than “00”, sand holes with a diameter of less than 15 mm are allowed to be blocked with the same material and their hardness should be lower than the hardness of the surrounding material. There should be no more than four places on the working surface, and the distance between them should be no less than 80mm.
3. On the opposite sides, threaded holes or cylindrical holes for lifting equipment such as handles and lifting rings should be provided. When designing the hoisting position, consideration should be given to minimizing changes due to hoisting.
4. According to the user's requirements, after the threaded holes or grooves are set on the working surface of the board, these parts should not appear convex above the working surface.
5. It should be made of gray cast iron or alloy cast iron with high quality fine particles.
6. The hardness of the working surface should be HB 170-220.
7. The working surface should adopt the scraping process. For the “3” grade flat working surface, the planing process can also be adopted. The surface roughness of the planing work surface should be no more than 5um according to the arithmetic mean deviation of the contour.
8, should be subjected to stability processing and demagnetization.
Flat degree: can be divided into laboratory level (Reference), verification level (Master), tool level (Working) level
Planar Grinding: At very early stages, people used three platforms to match each other to create a true flat plane. A skilled and patient grindstone master can create an unbelievable level of flatness without the use of any measuring instrument, but by using three platforms to match each other and doing multiple 90-degree rotations.
Flatness: 
1.AA grade: its flatness (μm) = 1+1.6D2 (D is the diagonal length or diameter of the platform), used for highly accurate measurements, often used in the laboratory.
2. Class A: The flatness is twice the error of AA grade, which is often used in the inspection of precision measuring tools in the tool inspection room.
3. Class B: The flatness is four times the error of AA level, which is often used in tool inspection room or in the field to test gage or scribing.
